There was a line of raised stones running in the marsh alongside the road. Julian stood on one of these peering at the flat marsh.

  'It's mud,' he said. 'Loose, squelchy mud! Look, when I touch it with my foot it moves! It would soon suck me down if I trod heavily on it.'

  Anne didn't like it. She called to Julian. 'Come up on the road again. I'm afraid you'll fall in.'

  Mists were wreathing and swirling over the salty marshes. It was a weird place, cold and damp. None of the children liked it. Timmy began to bark in the car.

  'Tim will scratch the car to bits if we don't get back,' said George. So they all went back, rather silent. Julian wondered how many travellers had been lost in that strange sea-marsh.

  'Oh, there's many that's never been heard of again,' said the driver, when they asked him. 'They do say there's one or two winding paths that go to the hill from the mainland, that were used before the road was built. But unless you know every inch of them you're off them in a trice, and find your feet sinking in the mud.'

  'It's horrid to think about,' said Anne. 'Don't let's talk about it any more. Can we see Castaway Hill yet?'

  'Yes. There it is, looming up in the mist,' said the driver. 'The top of it is out of the mist, see? Queer place, isn't it?'

  The children looked in silence. Out of the slowly moving mists rose,a tall, steep hill, whose rocky sides were as steep as cliffs. The hill seemed to swim in the mists, and to have no roots in the earth. It was covered with buildings which even at that distance looked old and quaint. Some of them had towers.

  'That must be Smuggler's Top, right at the summit,' said Julian, pointing. 'It's like an old building of centuries ago - probably is! Look at the tower it has. What a wonderful view you'd get from it.'

  The children gazed at the place where they were to stay. It looked exciting and picturesque, certainly - but it also looked rather forbidding.

  'It's sort of - sort of secret, somehow,' said Anne, putting into words what the others were thinking. 'I mean it looks as if it had kept all kinds of queer secrets down the centuries. I guess it could tell plenty of tales!'

  The car drove on again, quite slowly, because the mists came down thickly. The road had a line of sparkling round buttons set all along the middle, and when the driver switched on his fog-lamp, they shone brightly and guided him well. Then as they neared Castaway Hill the road began to slope upwards.

  'We go through a big archway soon,' said the driver. 'That used to be where the city gate once was. The whole town is surrounded by wall still, just as it used to be in olden times. It's wide enough to walk on, and if you start at a certain place, and walk long enough, you'll come round to the place you started at!'

  All the children made up their minds to do this without fail. What a view they would have all round the hill, if they chose a fine day!

  The road became steeper, and the driver put the engine into a lower gear. It groaned up the hill. Then it came to an archway, from which old gates were fastened back. It passed through, and the children were in Castaway.

  'It's almost as if we've gone back through the centuries, and come to somewhere that existed ages ago!' said Julian, peering at the old houses and shops, with their cobbled streets, their diamond-paned windows, and stout old doors.

  They went up the winding high street, and came at last to a big gateway, set with wrought-iron gates. The driver hooted and they opened. They swept into a steep drive, and at last stopped before Smuggler's Top.

  They got out, feeling suddenly shy. The big old house seemed to frown down at them. It was built of brick and timber, and its front door was as massive as that of a castle.

  Queer gables jutted here and there over the diamond-paned windows. The house's one tower stood sturdily at the east side of the house, with windows all round. It was not a square tower, but a rounded one, and ended in a point.

  'Smuggler's Top!' said Julian. 'It's a good name for it somehow. I suppose lots of smuggling went on here in the old days.'

  Dick rang the bell. To do this he had to pull down an iron handle, and a jangling at once made itself heard in the house.

  There was the sound of running feet, and the door was opened. It opened slowly, for it was heavy.

  Beyond it stood two children, one a girl of about Anne's age, and the other a boy of Dick's age.

  'Here you are at last!' cried the boy, his dark eyes dancing. 'I thought you were never coming!'

  'This is Sooty,' said Dick to the girls, who had not met him before. They stared at him.

  He was certainly very very dark. Black hair, black eyes, black eyebrows, and a brown face. In contrast to him the girl beside him looked pale and delicate. She had golden hair, blue eyes and her eyebrows were so faint they could hardly be seen.

  'This is Marybelle, my sister,' said Sooty. 'I always think we look like Beauty and the Beast!'

  Sooty was nice. Everyone liked him at once. George found herself twinkling at him in a way quite strange to her, for usually she was shy of strangers, and would not make friends for some time. But who could help liking Sooty with his dancing black eyes and his really wicked grin?

  'Come in,' said Sooty. 'Driver, you can take the car round to the next door, and Block will take in the luggage for you and give you tea.'

  Suddenly Sooty's face lost its smile and grew very solemn. He had seen Timmy!

  'I say! I say - that's not your dog, is it?' he said.

  'He's mine,' said George, and she laid a protecting-hand on Timmy's head. 'I had to bring him. I can't go anywhere without him.'

  'Yes, but - no dogs are allowed at Smuggler's Top,' said Sooty, still looking very worried, and glancing behind him as if he was afraid someone might come along and see Timmy. 'My stepfather won't allow any dogs here. Once I brought in a stray one and he licked me till I couldn't sit down - my stepfather licked me, I mean, not the dog.'

  Anne gave a frightened little smile at the poor joke. George looked stubborn and sulky.

  'I thought - I thought maybe we could hide him somewhere while we were here,' she said. 'But if that's how you feel, I'll go back home with the car. Good-bye.'

  She turned and went after the car, which was backing away. Timmy went with her. Sooty stared, and then he yelled after her. 'Come back, stupid! We'll think of something!'

  Chapter Five

  SOOTY LENOIR

  SOOTY ran down the steps that led to the front door, and tore after George. The others followed. Marybelle went too, shutting the big front door behind her carefully.

  There was a small door in the wall just where George was. Sooty caught hold of her and pushed her roughly through the door, holding it open for the others.

  'Don't shove me like that,' began George, angrily. 'Timmy will bite you if you push me about.'

  'No, he won't,' said Sooty, with a cheerful grin. 'Dogs like me. Even if I boxed your ears your dog would only wag his tail at me.'

  The children found themselves in a dark passage. There was a door at the farther end. 'Wait here a minute and I'll see if the coast is clear,' said Sooty. 'I know my stepfather is in, and I tell you, if he sees that dog he'll pack you all into the car again, and send you back! And I don't want him to do that because I can't tell you how I've looked forward to having you all!'

  He grinned at them, and their hearts warmed towards him again, even George's, though she still felt angry at being so roughly pushed. She kept Timmy close beside her.

  All the same everyone felt a bit scared of Mr Lenoir. He sounded rather a fierce sort of person!

  Sooty tiptoed to the door at the end of the passage and opened it. He peeped into the room there, and then came back to the others.

  'All clear,' he said. 'We'll take the secret passage to my bedroom. No one will see us then, and once we're there we can make plans to hide the dog. Ready?'

  A secret passage sounded thrilling. Feeling rather as if they were in an adventure story, the children went quietly to the door and into the room beyond. It was a dark, oak-panelle
d room, evidently a study of some sort, for there was a big desk there, and the walls were lined with books. There was no one there.

  Sooty went to one of the oak panels in the wall, felt along it deftly, and pressed in a certain place. The panel slid softly aside. Sooty put in his hand and pulled at something. A much larger panel below slid into the wall, and left an opening big enough for the children to pass through.

  'Come on,' said Sooty in a low voice. 'Don't make a row.'

  Feeling excited, the children all passed through the opening. Sooty came last, and did something that shut the opening and slid the first panel back into its place again.

  He switched on a small torch, for it was pitch dark where the children were standing.

  They were in a narrow stone passage, so narrow that two people could not possibly have passed one another unless both were as thin as rakes. Sooty passed his torch along to Julian, who was in front.

  'Keep straight on till you come to stone steps,' he said. 'Go up them, turn to the right at the top, and keep straight on till you come to a blank wall, then I'll tell you what to do.'

  Julian led the way, holding up the torch for the others. The narrow passage ran straight, and came to some stone steps. It was not only very narrow but rather low, so that Anne and Marybelle were the only ones who did not have to bend their heads.

  Anne didn't like it very much. She never liked being in a very narrow enclosed space. It reminded her of dreams she sometimes had of being somewhere she couldn't get away from. She was glad when Julian spoke. 'The steps are here. Up we go, everyone.'

  'Don't make a row,' said Sooty, in a low voice. 'We're passing the dining-room now. There's a way into this passage from there too.'

  Everyone fell silent, and tried to walk on tiptoe, though this was unexpectedly difficult when heads had to be bent and shoulders stooped.

  They climbed up fourteen steps, which were quite steep, and curved round half-way. Julian turned to the right at the top. The passage ran upwards then, and was as narrow as before. Julian felt certain that a very fat person could not possibly get along it.

  He went on until, with a start, he almost bumped into a blank stone wall! He flashed his torch up and down it. A low voice came from the back of the line of children.

  'You've got to the blank wall, Julian. Shine your torch up to where the roof of the passage meets the wall. You will see an iron handle there. Press down on it hard.'

  Julian flashed his torch up and saw the handle. He put his torch into his left hand, and grasped the thick iron handle with his right. He pressed down as hard as he could.

  And, quite silently, the great stone in the middle of the wall slid forward and sideways, leaving a gaping hole.

  Julian was astonished. He let go the iron handle and flashed his torch into the hole. There was nothing but darkness there!

  'It's all right, it leads into a big cupboard in my bedroom!' called Sooty from the back. 'Get through, Julian, and we'll follow. There won't be anyone in my room.'

  Julian crawled through the hole and found himself in a spacious cupboard, hung with Sooty's clothes. He groped his way through them and bumped against a door. He opened it and at once daylight flooded into the cupboard, lighting up the way from the passage into the room.

  One by one the others clambered through the hole, lost themselves in clothes for a moment and then went thankfully into the room through the cupboard door.

  Timmy, puzzled and silent, followed close beside George. He had not liked the dark, narrow passage very much. He was glad to be in daylight again!

  Sooty, coming last, carefully closed the opening into the passage by pressing the stone back. It worked easily, though Julian could not imagine how. There must be some sort of pivot, he thought.

  Sooty joined the others in his bedroom, grinning. George had her hand on Timmy's collar. 'It's all right, George,' said Sooty. 'We're quite safe here. My room and Marybelle's are separate from the rest of the house. We're in a wing on our own, reached by a long passage!'

  He opened the door and showed the others what he meant. There was a room next to his, which was Marybelle's. Beyond stretched a stone-floored, stone-walled passage, laid with mats. At the end of it a big window let in light. There was a door there, a great oak one, which was shut.

  'See? We're quite safe here, all by ourselves,' said Sooty. 'Timmy could bark if he liked, and no one would know.'

  'But doesn't anyone ever come?' said Anne, surprised. 'Who keeps your rooms tidy, and cleans them?'

  'Oh, Sarah comes and does that every morning,' said Sooty. 'But usually no one else comes. And anyway, I've got a way of knowing when anyone opens that door!'

  He pointed to the door at the end of the passage. The others stared at him.

  'How do you know?" said Dick.

  'I've rigged up something that makes a buzzing noise here, in my room, as soon as that door is opened,' said Sooty, proudly. 'Look, I'll go along and open it, while you stay here and listen.'

  He sped along the passage and opened the heavy door at the end. Immediately a low buzzing noise sounded somewhere in his room, and made everyone jump. Timmy was startled too, pricked up his ears, and growled fiercely.

  Sooty shut the door and ran back. 'Did you hear the noise? It's a good idea, isn't it? I'm always thinking of things like that.'

  The others thought they had come to rather a queer place! They stared round Sooty's bedroom, which was quite ordinary in its furnishings, and in its general untidiness. There was a big diamond-paned window, and Anne went to look out of it.

  She gave a gasp. She had not expected to look down such a precipice! Smuggler's Top was built at the summit of the hill, and, on the side where Sooty's bedroom was, the hill fell away steeply, down and down to the marsh below!

  'Oh look!' she said. 'Look how steep it is! It really gives me a very queer feeling to look down there!'

  The others crowded round and looked in silence, for it certainly was strange to gaze down such a long way.

  The sun was shining up on the hill-summit, but all around, as far as they could see, mists hid the marsh and the far-off sea. The only bit of the marsh that could be seen was far down below, at the bottom of the steep hill.

  'When the mists are away, you can see over the flat marshes to where the sea begins,' said Sooty. 'That's quite a fine sight. You can hardly tell where the marsh ends and sea begins except when the sea is very blue. Fancy, once upon a time, the sea came right up and around this hill, and it was an island.'

  'Yes. The innkeeper told us that,' said George. 'Why did the sea go back and leave it?'

  'I don't know,' said Sooty. 'People say it's going back farther and farther. There's a big scheme on foot to drain the marsh, and turn it into fields, but I don't know if that will ever happen.'

  'I don't like that marsh,' said Anne, with a shiver. 'It looks wicked, somehow.'

  Timmy whined. George remembered that they must hide him, and make plans for him. She turned to Sooty.

  'Did you mean what you said about hiding Tim?' she asked. 'Where shall we put him? And can he be fed? And how can we exercise him? He's a big dog, you know.'

  'We'll plan it all,' said Sooty. 'Don't you worry. I love dogs, and I shall be thrilled to have Timmy here. But I do warn you that if my stepfather ever finds out we shall probably all get a jolly good thrashing, and you'll be sent home in disgrace.'

  'But why doesn't your father like dogs?' said Anne puzzled. 'Is he afraid of them?'

  'No, I don't think so. It's just that he won't have them here in the house,' said Sooty. 'I think he must have a reason for it, but I don't know what it is. He's a queer sort of man, my stepfather!'

  'How is he queer?' asked Dick.

  'Well - he seems full of secrets,' said Sooty. 'Queer people come here, and they come secretly without anyone knowing. I've seen lights shining in our tower on certain nights, but I don't know who puts them there or why. I've tried to find out, but I can't.'

  'Do you think - do you think
your father is a smuggler?' said Anne, suddenly.

  'I don't think so,' said Sooty. 'We've got one smuggler here, and everyone knows him! See that house over there to the right, lower down the hill? Well, that's where he lives. He's as rich as can be. His name is Barling. Even the police know his goings-on, but they can't stop him! He is very rich and very powerful, so he does what he likes - and he won't let anyone play the same game as he plays! No one else would dare to do any smuggling in Castaway, while he does it!'

  'This seems rather an exciting place,' said Julian. 'I have a kind of feeling there might be an adventure somewhere about!'

  'Oh no,' said Sooty. 'Nothing ever happens, really. It's only just a feeling you get here, because the place is so old, so full of secret ways and pits and passages. Why, the whole hill is mined with passages in the rock, used by the smugglers of olden times!'

  'Well,' began Julian, and stopped very suddenly. Everyone stared at Sooty. His secret buzzer had suddenly barked from its hidden corner! Someone had opened the door at the end of the passage!

  Chapter Six

  SOOTY'S STEPFATHER AND MOTHER

  'SOMEONE'S coming!' said George, in a panic. 'What shall we do with Tim? Quick!'

  Sooty took Timmy by the collar and shoved him into the old cupboard, and shut the door on him. 'Keep quiet!' he commanded, and Timmy stood still in the darkness, the hairs at the back of his neck standing up, his ears cocked.

  'Well,' began Sooty, in a bright voice, 'perhaps I'd better show you where your bedrooms are now!'

  The door opened and a man came in. He was dressed in black trousers and a white linen coat. He had a queer face. 'It's a shut face,' thought Anne to herself. 'You can't tell a bit what he's like inside, because his face is all shut and secret.'

  'Oh hallo, Block,' said Sooty, airily. He turned to the others. 'This is Block, my stepfather's man,' he said. 'He's deaf, so you can say what you like, but it's better not to, because though he doesn't hear he seems to sense what we say.'
