The high-pitched thin sound was barely audible. Gradually, it grew louder, throwing numerous passersby into confusion. Some people started to throw back their heads and to look intently into the sky.

The sound came from a tiny spot high in the sky. It was changing, disturbingly vibrating, as if complaining and warning everybody of some disaster that was happening there.

People felt this and kept their eyes on the spot with alarm. Smiles disappeared, and silence fell all around. Anxiety gripped the drivers of the vehicles going by. Some of them stopped, got out of their cars, and started to look into the sky, too.

The spot became larger. Now, one could see with an unaided eye that some badly controlled aircraft was making a crash landing. Everybody sensed that the crew was fighting desperately to keep the craft gliding slowly and prevent it plummeting down.

The sound became louder and even more plaintive, as if it came from a living creature.

The unusual round shape of the spaceship stood out sharply against the background of Westminster Palace. It suddenly turned around Big Ben, nearly knocking down one of the towers of the palace.

The sound coming from the spaceship turned into a scream, the last cry for help choked with the Thames waters…

People hung on the bridge railing peering into the water. Air bubbles, rising from the depths of the river, were carried away by the current, and it seemed that nothing had happened, were it not for a strange bright light coming up from the water.

Suddenly, the atmosphere around the place of the accident became dry and brittle, multicolored electric flashes, followed by unpleasant cracks, ran across the walls of the nearest buildings.

All vehicles on the bridge stopped, and three more spaceships of the same shape hung over the river, their dull metallic color evidence of long traveling in space. They formed a triangle over the place where the light emitted from the water, motionlessly hovering in the air.

«The London Eye» stopped, but no cries were heard from there.

Only Big Ben’s clock chimes broke the silence.

Soon, there appeared a new spaceship in the center of the triangle, of much bigger size.

People heard a weak buzzing, and the drowned spaceship slowly started rising out of the water. First, its upper part became visible, and then it all came out of the water that flowed down the spaceship in streams.

The new spaceship opened a huge receiving bay, and the drowned spaceship was pulled into it. The door closed, and the spaceship disappeared.

In short time the three spaceships, guarding the point of impact, disappeared too.

People regained their composure, exchanged uncomprehending glances, and continued their own business.

Vehicles started up on their own, and the drivers who got out of their cars looked around perplexed, as if asking – what am I doing here?

The life of the town got back into a grove, as if nothing had happened there.

And had anything really happened?

Chapter 1

Their departure was being obviously delayed – one passenger did not board, and ground crew was looking for his baggage. The air in the cabin was stuffy, because the air conditioning was not switched on yet.

When all problems were solved, the huge plane soared heavily upwards. The cabin crew was excellent, and flight attendants quickly served the passengers. All were restored to good humor, and passengers got busy with their own pastimes.

A group of young people stood out against the background of typical passengers. They were briskly exchanging remarks, paying no attention to recent discomfort and to other people in the cabin. Their light-hearted laughter was evidence of good moods, and that soon rest was waiting for them.

The plane started descending, sharply turned over the sea, and landed at the airport. The baggage was got, and the cheerful company noisily headed for the exit. A bright sunny day welcomed all who arrived at sea side.

The town they arrived in was a real sea pearl. Situated on the only bay there, it was sheltered from high winds by mountains from three sides.

The company of young people picked their way towards it. Having driven through an old bypass road up the mountain to the top of a low pass, they got out of the cab and called. In some time, a door in the big metal gates opened, and they went in.

The friends walked down a road with a slight grade, and in about three hundred feet, after a steep turn, they saw a two-storied stone house, looking like a ship, with an attic and a big terrace, like a captain’s bridge. It seemed that it stood at its moorings, by a small mountain, which hid it from all misfortunes.

The terrace gave a beautiful view of the town and the bay. The mountain to the right of the house was particularly impressive. It looked like a huge petrified crocodile, with a hotel on the mountain as its eye.

The air here was also unique. A morning offshore breeze blew away all evaporating waste products to the sea. Instead, the air of the ancient relict box-tree grove filled in all the space around.

A narrow mountain river with transparent purling water flew out of the ravine. It divided the town into two parts. One part was occupied by dwellings, and the other by entertainment and theatre buildings.

In the afternoon, a breeze blew from the sea, filling the territory with its summer smell.

When the breezes stopped their work, the fragrance of all flowers and blooming trees, gathered here from all over the world, flooded this beautiful bowl by the sea…

An iron door opened, letting the guests in. In a big hall, decorated with marble tiles, was a sofa, a big mirror in a gilded frame, and a small carved table with curved legs and a light marble top.

The guests put down their baggage and went to the living room.

The living room was lit by Italian bronze chandeliers and side lamps. By the fireplace, there were two green leather armchairs and a coffee table. A big green sofa, a huge TV set, and some pictures by modern artists added to the interior of this room.

The main windows of the house faced the bay, and the last rays of the setting sun painted the living room into different inimitable colors.

The living room joined the dining room through an arched passageway. The dining room was ready to receive guests. A crystal chandelier illuminated a dark incrusted table with tableware on it; crystal side lamps gave additional light to the room.

Thick soft carpet covered the floor, completing the interior.

The cheerful fuss of guests noisily settling into their rooms animated the whole house. Everybody tried to choose a room, facing the bay at the foot of the mountain. Guests opened the windows, and rhythmic music filled in the surroundings.

Not all young people were guests, though – Julia was the master’s daughter, and, as hostess, gave orders to her friends, helping them to settle and unpack their things. Soon, everybody went quiet, took a shower, changed into summer clothes and came down to the dining room.

Girls seated young men around the table and went to the kitchen.

In the kitchen, they saw a huge cake, ordered by Julia’s parents for the occasion of their arrival, and lots of cold snacks, that were quite to the point in such hot weather.

The girls were quickly carrying the dishes to the dining room, and putting them on the table closer to the young boys.

Such attention and care pleased the young men. Full as they were, they asked for more. Joking, the girls good-naturedly obeyed and put more food on their plates.

When the dinner was over, the friends went to their rooms to have a rest. After their rest they had to make the acquaintance of the dogs that guarded the house.

Nord – «the Lord Dog» – warily came up to a guest, slowly and deeply breathed in his or her smell, and only then put a stamp – nuzzled up the guest with his wet nose, leaving his smell on the person.

Alfa was his opposite. She did not want to accept anybody, and could just keep her patience with the strangers. Each time she looked at them with suspicion, she kept her distance. To show the strangers how much she didn’t trust them, Alfa, one by one, carefully took her hostess’s house shoes to the farthest corner from the guests’ spot. Her looks clearly showed that the hostess’s shoes were under good protection.

The last dog, Berta, was very young yet, and copied the older dogs in her behavior. She instantly joined their company in any undertaking.

The three dogs were German Shepherds, so nobody was going to take liberties with them. Nobody, but Michael. His behavior with the dogs was quite boyish, and, in response, they did not reveal any aggression towards him. It seemed they understood that he would never be different, and were indulgently patient with his tricks.

Julia took out a big piece of beef, bought specially for the dogs on her way home, fairly divided it into three parts, and put a piece onto each dog’s plate. Then she poured clean cold water into bowls and carried everything to the yard, in front of the main entrance.

The dogs started eating all at once, standing with their front legs far apart over the plates with food. From time to time, each of them began to stamp against the ground with its hind legs. This showed that they liked the food very much.

Our company was watching the dogs’ feast from the bench in the yard.

Suddenly, Alfa, seeing that the delicacies in the other dogs’ plates were coming to an end, ran up towards the iron gates, loudly barking on her way. Nord rushed after her, outran the dog, and dashed forward. Berta, like a flash, ran after Nord, and cunning Alfa, having waited at the turn when they would run past her, quickly returned to their plates, and as quickly ate everything on them. Then she licked clean the plates, and went to have a rest in the shade, inside the yard, with an obvious feeling that her duty had been done.

The young people curled up, looking at this cunning muzzle, licking herself all over. This trick was worked through by Alfa, and she used it not once. When the other two dogs, hot after running, returned, they sniffed around their plates, drank cold water, and also went to the shade for an afternoon rest.

It was still hot, and everybody was worn out by the heat. Michal suggested that they could go swimming in the sea. Michael was a ringleader, with lots of ideas on his mind all the time. Not all his ideas were good, but this one pleased everybody.

Looking at his T-shirt, soaked with sweat, Julia assumed that she looked no better. Linda, her friend, also agreed to walk down the mountain to the sea, and William just stood up, tacitly approving the suggestion. He preferred deeds to words. William kept his silence more often than he spoke. He listened to others and gave a meaning to what was said; he did not like to be an object of somebody’s analysis.

Preparations were not long – swimming suits were put on, and terry towels thrown over shoulders – this was all they needed to bathe in the sea.

Chapter 2

The hot southern sun, which supplied the earth with heat and sultriness not so long ago, was quickly rolling down to the horizon. The day was drawing to a close. Crickets started performing their nighttime symphony.

The walk down to the sea was not difficult. The path went through a small town park. The warm southern air was composed of the fragrance of all blooming plants and flowers, but the aroma of the plants one passed by prevailed.

Bushes of jasmine and sprays of wisteria smelt particularly sweet. The fragrance was so thick, that it seemed one could drink it. You would like just to sit down on a bench and breathe it in…

The sea met the friends with an empty beach and warm water. Shingles, warmed-up by the day’s sun, generously gave away their warmth. There were small oases of sand on the beach, and our friends set to dig William into the sand, doing that with great pleasure.

When a small hill grew over the young man, Michael fell back down on it. William was silent and only closed his eyes to avoid getting sand in them, while Michael’s bulk gamboled on this hand-made hill.

The girls were slowly coming into the sea. Michael joined them, leaving William alone. The latter had complete freedom to decide how to get out of the sand.

Any splashes of water were followed by microorganisms’ glow. Bioluminescence was exciting and uncommon. Having pushed from the sea bottom, young people zealously stroked on the water with their hands causing impetuous glow of microorganisms and additional ripples on the moon path that had appeared on the water. Having become quiet, they slowly swam to the buoy and back.

Swimming on her back and viewing the stars that became brighter as it grew darker, Julia dropped slightly behind her friends. The night was quickly setting in.

The bright stars and the glow of the microorganisms that enveloped the swimmers created a magical picture of the night sea, so the phrase «Come to us!» said by someone, fell in with the magic of the night and didn’t surprise Julia. But when this phrase was repeated, and repeated more insistently, Julia looked around, but saw nobody, and quickly swam back to the shore.

Her friends, ready to go home, were waiting for her on the beach. They were briskly discussing the night’s sea-bathing. Julia attentively looked them over. Judging by their behavior, nobody had any relation to the voice she had heard.

«Most probably, it’s somebody’s joke», she thought, and joined the conversation. The young people were particularly impressed by the microorganisms’ glow in the warm water. Julia explained that such a phenomenon could be observed during only one month, when the water was at its warmest. Thus talking, they soon came back home.

Julia’s parents were waiting for them. They had a lot of questions for the young people, and all evening were asking them about their lives in the other town.

Nobody wanted to go to bed. Somebody switched on a radio at a low volume, and the boys began to light a fire from kindling in the barbecue. Then they put charcoal there, and, in a while, small pieces of meat.

The smell of frying meat and fat, dropping on the charcoal and burning there, filled the whole yard. The dogs knew that they would get their pieces too, and attentively watched what was going on in the yard.

The boys turned over the meat together – William was giving some light with a lantern to the pieces of meat, and Michael was carefully taking them with tongs, looking them over, and then moving pieces that weren’t done yet to where the heat was stronger.

The table was laid in the yard. The fragrance of a warm southern night mixed in the air with the smell of fried meat…

Crickets and slight crackling of charcoal, slowly getting cold against the background of the illuminated town and the vast dark blue panoramic sky, studded with blinking stars, added to this tangible composition.

It was already late, charcoal went out, music was turned off, and young people, yawning and stretching themselves from time to time, leisurely dispersed to their rooms.

In the morning, Michael woke up everybody very early:

«Enough sleep, or you’ll sleep away your whole life!» he yelled, knocking on all doors.

After such an awakening, sleep was gone for good. All quickly got up and went to take a shower. Julia tore away a disposable tooth brush set from a hanging band. The set contained water for preliminary rinsing, toothpaste and mouth wash. She cleaned her teeth, tore away a new set and gave it to Linda. Having examined the novelty, Linda was impressed – she had never seen such a thing before.

In some time, the girls fixed themselves up and went downstairs.

In the yard Michael was capturing the dogs on video – they all at once were sticking their tongues out, to one side, trying to push something out of their mouths. The dogs tossed their heads, but nothing came of this. Something remained in their mouths.

Michael roared with laughter; the dogs, however, did not reveal any displeasure. It appeared he had stuck some soft sticky candies on the dogs’ posterior teeth. It was incomprehensible how they allowed him to do that.

This silent concert made everybody else laugh, too. Michael suggested:

«Let’s walk the dogs down the street to frighten passersby – nobody will understand what’s happened to them. The candies will take five minutes to melt, and then we’ll stick in some more…»

Nobody agreed, however, and the answer was unanimous – to leave the dogs in peace.

Breakfast was ready. The dining room was waiting for guests, and the company started eating up homemade buns and rolls, baked in advance by farsighted parents.

The sun burst free of the mountains’ grip, and began its visible stalking along the dome of the sky. Morning coolness was gradually transforming into daytime heat. It was better to go to the sea before the sun rose high.

From the mountain one could watch dozens of boats that combined leisure and morning fishing. They were one to two miles off-shore. One could even see rods, and caught fish, which sparkled in the sun near some fishers.

Chapter 3

Walking through the town, the friends dropped in a shop and bought lots of useful and necessary things – beach mats to lie on the sand, hats, water and fruit. In expectation of swimming in the sea, rest and sunbathing, they went to a far beach at the cape edge of the «Crocodile» mountain.

The trip was not long, and soon they came to the beach. Linda went first into the sea, splashing water on herself.

Michael couldn’t keep from sprinkling her wet back with sand. The sand clung to her body, and she plunged into the sea to wash it off. Having bathed, she began to splash water on her friends, who were cautiously coming into the sea. Wet from Linda’s splashes, the friends all at once plunged into the water. Then they all pounced on Linda and shoved her into the water. Linda, who did not want to get her hair wet, was quite wet now.

After long racing and diving for awhile, the friends decided to play beach volleyball. Their ball was well pumped, and, from time to time, after somebody’s heavy hit, it went into the sea. One of the friends, nearest to the water, had to swim to catch the ball not to allow it to be taken away by the current.

After playing and another long swim in the sea, the friends decided to get a tan. They put straw hats on, lay on their mats, closed their eyes, and let the sun work on them.

The sea was still. Only lightly breaking waves stroked the sand, filling the air with the sounds of splashing water and everlasting sand rustling.

Julia looked at her friends, sprawling on their mats, and decided to swim alone. She missed the sea so much, that she couldn’t lie on the beach for a long time.

Having taken snorkeling equipment out of the bag, Julia went into the sea, put on flippers, mask and snorkel, and swam along a man-made levee, built of big boulders and protruding into the sea for a short distance.

Clean cool morning water made it possible to examine the underwater world in detail. Small crabs and fish were fussing near their shelters, and immediately disappeared at the least danger. Larger specimens were there in deeper waters, and Julia fearlessly swam farther from the shore.

On the rock bottom, covered with swinging drift weeds almost everywhere, Julia could see small clearings of pebbles and sand.

Here, at this depth, crabs were larger, and Julia attempted to catch one of them with her hands. The crab was faster, however, and, in a sideways manner, quickly ran away and hid under a big stone.

Thanks to flippers, mask and snorkel she could not only swim at the distance of ten feet from the bottom, but also have a good look at the underwater world, surrounding her. Fish of every kind, swimming next to her and not in the least afraid of a human being, were iridescent. Colors were bright and rich in comparison with those in the air and, on the land, where they seemed to be their poor copies.

Clean shells, slightly rubbed with drift weeds and sea sand, were real masterpieces, created by nature – the greatest master.

Julia decided to collect some for her friends. Having filled her lungs with air as she was used to, Julia dived to get each shell that took her fancy and put it into the net, fixed to her waistband. Soon her net was full with shells.

Julia felt a bit tired and had already decided to swim back to the shore, when some unfamiliar voice called her:

«Come to us!»

Julia looked around, but saw nobody nearby. She thought she was hearing things and swam fast to the shore.

Swimming was becoming more and more difficult for Julia; her arms and legs became heavy. Julia thought that she spent too much time in the water for the first time and got tired. She wasn’t by the sea for a long time – she studied in another town, far from her home.

Julia turned over on her back to rest on the water.

The shore was not far, only about five hundred feet. She spread out her arms, slightly threw back her head into the water, and relaxed to gather strength.

At first the rest was pleasant. Julia closed her eyes to protect them from the bright sun, and enjoyed bobbing slowly on the small waves.

Suddenly, her body started slowly sinking into the sea, against her will. She could not cry – the water had already covered her face. Her friends were baking in the sun behind the man-made levee, and nobody saw her. Soon she heard the same voice. It calmed her:

«Don’t worry, you’ll be OK!»

Her sinking was gradually quickening. The sun turned into a small spot, hardly seen through the water above her, and, in an instant, disappeared at all. Her body was swung around and dragged into the depths at a great pace.

Julia was rushing along under the water with the speed of an express train. Fish, like fearful birds, scattered different ways. Larger fish and sea animals swerved to avoid collision.

Her travel was going on above a steep slope, ending abruptly into a fathomless pit. She was sweeping past ship and plane wrecks, which caught hold of the eroded rocky surface of the slope. Julia had no time to descry smaller details of the constructions on the slope.

Her physical state was very strange – she could see, but her body did not feel anything. Moving was fast and painless.

The first fear ceased, and Julia could already examine her surroundings more attentively. The slope ended, but her fall into a fathomless pit was going on.

Lower, the walls of the pit were upright and smooth, with rare bushes of underwater plants, which, by a miracle, caught hold of small hollows or cracks to survive.

Fish and sea animals she met on her way seemed to be brought here from some fantasy novel.

A huge squid, of the size of a carriage, was also plunging into the depth nearby. It was a slow and grand plunging – at least so it seemed to Julia. A sheet of water it let out sharply speeded its motion, tentacles stretched along its body, and the squid was plunging, in splendid solitude, until its motion was slowed down again. Then the whole process was repeated.

Some fish glowed in the darkness; others had only one or several lights, which twinkled in bottomless depths. It would seem amusing to Julia if she weren’t carried past one such visible light. It appeared the light was over a huge large-toothed mouth with prodigious lower jaw, decorated with several rows of sharp large teeth, which stuck out every way. The monster’s body was so long that Julia didn’t see its end. It was lost in the terrifying darkness of this underwater bottomless abyss.

Light did not filter through the water any more, and she was moving in full darkness. At last, the dragging down was over. It was the bottom of the abyss. Suddenly, a pale light appeared, and Julia could look everything over, as far as the lighting allowed it.

She saw that she was on a rocky bottom with small patches of sand in hollows. There was neither mud nor silt – a strong bottom stream carried everything away in this narrow crack. Only in some places on the walls there was dark brown moss, and rare shrubs jutted out here and there.

Julia ran her hand around and found a strange layer of water, surrounding all her body. It made possible living in the water, without oxygen, and protected her from the enormous pressure.

This water layer seemed to be alive. It consisted of water mussels, which were tightly clasped to each other; however, they were not staying still, but moving, gleaming with silver pearl with blue or coral tint, like small transparent sea eels.

She took only a quick look of at her surroundings. Her movement scared some flat fish, which jumped out from the bottom, raising the sand up, and swam away behind the rock.
