When the others came back she told them what she was going to do, speaking in a low voice through the door.

  'I'll get down on the wall, walk along it for some way, and then jump down and creep back, she said. 'You get some food for me somehow, and I'll have it. Then tonight, when everyone has gone to bed I'll get into the study again and find the way through to the secret passage. Sooty can help me. Then I can get Timmy.'

  'Right,' said Sooty. 'Wait till it's fairly dark before you go down the ladder, though. Block has gone to his room with a bad headache, but Sarah and Harriet are in the kitchen, and you don't want to be seen.'

  So, when the twilight hung like a soft purple curtain over the house, George slid down the rope-ladder out of the window. She only needed to let about a quarter of it out for it was far too long for such a short distance.

  She fastened it to the legs of her heavy little oak bed. Then she climbed out of the window and slid quietly down the rope-ladder.

  She passed the kitchen window, which fortunately had its blinds drawn down now. She landed squarely on the old wall. She had brought a torch with her so that she could see.

  She debated with herself what to do. She did not want to run any risk of coming up against either Block or Mr Lenoir. Perhaps it would be best to walk along the wall till she came to some part of the town she knew. Then she could jump off and make her way cautiously back up the hill, looking out for the others.

  So she began to walk along the broad top of the old wall. It was very rough and uneven in places, and many stones were missing. But her torch showed a steady light and she did not miss her footing.

  The wall ran round some stables, then round the backs of some quaint old shops. Then it ran round a big yard belonging to some house, and then round the house itself. Then down it went, around some more houses.

  George could look into those windows that were not curtained. Lights shone out from them now. It was queer being able to see into the windows without being seen. A little family sat at a meal in one room, their faces cheerful and happy. An old man sat alone in another, reading and smoking.

  A woman sat listening to a wireless, knitting, as George silently walked on the wall outside her window. Nobody heard her. Nobody saw her.

  Then she came to another house, a big one. The wall ran close against it, for it was built where the cliff ran steeply down to the marsh just there.

  There was a lighted window there. George glanced in as she passed. Then she stood still in great surprise.

  Surely, surely that was Block in there! He had his back to her, but she could have sworn it was Block. The same head, the same ears, the same shoulders!

  Who was he talking to? George tried to see - and all at once she knew. He was talking to Mr Barling, whom everyone said was a smuggler - the smuggler of Castaway Hill!

  But wait a minute - could it be Block? Block was deaf, and this man evidently wasn't. He was listening to Mr Barling, that was plain, and was answering him, though George could not hear the words, of course.

  'I oughtn't to be snooping like this,' said George to herself. 'But it's very strange, very puzzling and very interesting. If only the man would turn round I'd know at once if it was Block!'

  But he didn't turn. He just sat in his chair, his back to George. Mr Barling, his long face lighted up by the nearby lamp, was talking animatedly, and Block, if it was Block, was listening intently and nodding his head in agreement every now and again.

  George felt puzzled. If she only knew for certain that it was Block! But why should he be talking to Mr Barling - and wasn't he stone deaf after all then?

  George jumped down from the wall into a dark little passage and made her way through the town, up to Smuggler's Top. Outside the front door, hiding in the shadows was Sooty. He laid his hand on George's arm, making her jump.

  'Come on in. I've left the side-door open. We've got a fine spread for you!'

  The two slipped in at the side-door, tiptoed past the study, across the hall, and up to Julian's bedroom. Truly there was a spread there!

  'I went and raided the larder,' said Sooty, with satisfaction. 'Harriet was out, and Sarah had run along to the post. Block has gone to bed for a rest, because, he said, he had such an awful headache.'

  'Oh,' said George, 'then it couldn't have been Block I saw. And yet I'm as certain as certain can be that it was!'

  'Whatever do you mean?' asked the others, in surprise. George sat down on the floor and began to gobble up cakes and tarts, for she was terribly hungry. Between her mouthfuls she told them how she had got out of the window, walked along the city-wall, and found herself unexpectedly by Mr Barling's house.

  'And I looked into a lighted window there, and saw Block talking to Mr Barling - and listening to him and answering him!' she said.

  The others could not believe this. 'Did you see his face?' asked Julian.

  'No,' said George. 'But I'm certain it was Block. Go and peep into his room and see if he's there, Sooty. He wouldn't be back yet from Mr Barling's, because he had a glass full of something or other, which would take him some time to drink. Go and peep.'

  Sooty vanished. He came back quickly. 'He's in bed!' he said. 'I could see the shape of his body and the dark patch of his head. Are there two Blocks then? Whatever does this mean?'

  Chapter Fifteen

  STRANGE HAPPENINGS

  IT certainly was very puzzling - most of all to George, who felt so certain it had been Block talking to the well-known smuggler. The others did not feel so certain, especially as George admitted that she had not seen his face.

  'Is my father here yet?' asked George, suddenly, remembering that he was supposed to come that evening.

  'Yes. Just arrived,' said Sooty. 'Just before you came. I nearly got run over by the car! Just hopped aside in time. I was out there waiting for you.'

  'What are our plans?' asked George. 'I'll have to get Timmy tonight, or he'll be frantic. I think I'd better go and climb back through my window again now, in case Block comes along and finds I've disappeared. I'll wait till everyone is in bed and then I'll slip out of the window again, and you must let me into the house, Sooty, please. Then I'll go to the study with you and you must open the secret way for me. Then I'll find Timmy and everything will be all right.'

  'I don't see that everything will be all right,' said Sooty, doubtfully. 'But anyway, your plan is the only one to follow. You'd better get back into your room now, if you've had enough to eat.'

  I'll take a few buns back with me,' said George, stuffing them into her pocket. 'Sooty, come and knock at my door when everyone is in bed and I'll know then that it's safe for me to slip out of the window, and come into the house again.'

  It wasn't long before George was back in her room once more - just in time too, for Block appeared a little while after with a plate of dry bread and a glass of water. He unlocked the door and put them on the table.

  'Your supper,' he said. George looked at his blank face and disliked it so much that she felt she must do something about it. So she took up the water and threw it deftly at the back of his head.

  It dripped down his neck and made him jump. Block took a step towards her, his eyes gleaming - but Julian and Dick were by the door, and he did not dare to strike her.

  'I'll pay you out for that,' he said. 'See? You will never get that dog of yours back again!'

  He went out and locked the door. Julian called through as soon as he had gone.

  'What did you do that for, you idiot? He's a bad enemy to make.'

  'I know. I just couldn't help it somehow,' said George, forlornly. 'I wish I hadn't now.'

  The others had to go down to see Mr Lenoir. They left George feeling lonely. It was horrid to be locked up like this, even though she could escape through the window whenever she wanted to. She listened for the others to come back.

  They soon did, and reported their meeting with George's father.

  'Uncle Quentin is awfully tired and a bit cross, and frightfully annoyed with
you for misbehaving,' said Julian, through the door. 'He said you were to be locked up the whole of tomorrow too, if you don't apologise.'

  George didn't mean to apologise. She couldn't bear Mr Lenoir, with his false smiles and laughter, and his sudden queer rages. She said nothing.

  'We've got to go and have our supper now,' said Sooty. 'We'll save you some of it as soon as Block goes out of the room. Look out for a knocking on your door tonight. It'll be me, telling you everyone's in bed.'

  George lay on her bed, thinking. Many things puzzled her. She couldn't get them straight somehow. The signaller in the tower - the queer man, Block - Mr Barling's talk to a man who looked so like Block, but Block was all the time in his bed at home. As she lay thinking, her eyes closed, and she fell asleep.

  Anne went to bed with Marybelle, and came to whisper good-night to her. The boys all went into the next room, for Sooty was now to share Julian's and Dick's bedroom. George woke up enough to say good-night and then slept again.

  At midnight she awoke with a jump. Someone was knocking softly and impatiently on her door. It was Sooty.

  'Coming!' whispered George through the door, and took up her torch. She went to the window and was soon safely down the rope-ladder. She jumped down from the wall, and went to the side-door of the house. Sooty was there. She slipped in thankfully.

  'Everyone's gone to bed,' whispered Sooty. 'I thought your father and my stepfather were never going. They stayed talking in the study for ages!'

  'Come on. Let's go there,' said George, impatiently. They went to the study-door, and Sooty turned the handle.

  It was locked again! He pushed hard, but it wasn't a bit of good. It was well and truly locked!

  'We might have thought of that,' said George, in despair. 'Blow, blow, blow! What are we to do now?'

  Sooty thought for a few moments. Then he spoke in a low voice, in George's ear.

  'There's only one thing left to do, George. I must creep into your father's room - my old bedroom - when he is asleep - and I must get into the cupboard there, open the entrance to the secret passage, and slip in that way. I'll find Timmy and bring him back the same way, hoping that your father won't wake!'

  'Oh! Would you really do that for me?' said George, gratefully. 'You are a good friend, Sooty! Would you rather I did it?'

  'No. I know the way up and down that passage better than you do,' said Sooty. 'It's a bit frightening to be all alone there at midnight too. I'll go.'

  George went with Sooty up the stairs, across the wide landing, to the door at the end of the passage that led to Sooty's old room, where George's father was now sleeping. When they got there, George pulled his arm.

  'Sooty! The buzzer will go as soon as you open the door - and it will wake my father and warn him.'

  'Idiot! I disconnected it as soon as I knew my room was to be changed,' said Sooty, scornfully. 'As if I wouldn't think of that!'

  He opened the door that led into the passage. He crept up to his old room. The door was shut. He and George listened intently.

  'Your father sounds a bit restless,' said Sooty. 'I'll wait my chance to creep in, George, and then, as soon as possible, slip into the cupboard and open the secret passage to find Tim. As soon as I've got Timmy I'll bring him along to you. You could wait in Marybelle's room if you liked. Anne's there too.'

  George crept into the room next door, where Anne and Marybelle lay fast asleep. She left the door open, so that she might hear when Sooty returned. How lovely it would be to have dear old Timmy again! He would lick her and lick her.

  Sooty crept into the room where George's father lay, half-asleep. He made no sound. He knew every creaking board and avoided them. He made his way quietly to a big chair, meaning to hide behind it till he was certain George's father was sound asleep.

  For some time the man in the bed tossed and turned. He was tired with his long journey, and his mind was excited with his talk with Mr Lenoir. He muttered now and again, and Sooty began to feel he would never be sound asleep! He grew sleepy himself, and yawned silently.

  At last George's father grew quiet and peaceful. No more creaks came from the bed. Sooty cautiously moved out from behind the chair.

  Then suddenly something startled him. He heard a sound over by the window! But what could it be? It was a very small sound, like a tiny creak of a door.

  The night was rather dark, but the window, its curtains pulled right back, could easily be seen as a square of grey. Sooty fixed his eyes on it. Was someone opening the window?

  No. The window did not move. But something queer was happening under it, near the sill.

  A big window-seat was built in under the window, wide and comfortable. Sooty knew it well! He had sat on it hundreds of times to look out of the window. Now, what was happening to it?

  It looked as if the top, or lid of the seat was slowly moving upwards, bit by bit. Sooty was puzzled. He had never known it could be opened like that. It had always been screwed down, and he had thought it was just a seat and nothing else. But now it looked as if someone had unscrewed the top, and had hidden himself inside, lifting up the top like a lid when he thought it was safe.

  Sooty stared at the upward-moving lid, quite fascinated. Who was in there? Why had he hidden? It was rather frightening, seeing the lid move slowly, bit by bit.

  At last the lid was wide open and rested against the window-pane. A big figure cautiously and slowly got out, not making the slightest sound. Sooty felt his hair rising up on his head. He was afraid, terribly afraid. He could not utter a sound.

  The figure tiptoed over to the bed. He made a quick and sudden movement, and there was a stifled sound from George's father. Sooty guessed he had been gagged, so that he could not cry out. Still the boy could not move or speak. He had never been so scared in all his life.

  The intruder lifted the limp body from the bed, and went to the window-seat. He put George's father into the darkness there. What he had done to make him unable to struggle Sooty didn't know. He only knew that poor George's father was being put down in the window-seat, and couldn't seem to move a hand to help himself!

  The boy suddenly found his voice. 'Hie!' he yelled. 'Hie! What are you doing? Who are you?'

  He remembered his torch and switched it on. He saw a face he knew, and cried out in surprise. 'Mr Barling!'

  Then someone hit him a hard blow on the head and he remembered nothing more at all. He did not know that he was lifted into the window-seat too. He did not know that the intruder followed after him. He knew nothing.

  George, awake in the next room, suddenly heard Sooty's voice crying out. 'Hie!' she heard. 'Hie, what are you doing? Who are you?' And then, as she slipped out of bed, she heard the next cry. 'Mr Barling!'

  George was extremely startled. What was going on next door? She fumbled about for her torch. Anne and Marybelle were still asleep. George could not find her torch. She fell over a chair and banged her head.

  When at last she had found her torch she tiptoed, trembling, to the door. She shone her torch and saw that the door next to hers was a little ajar, just as Sooty had left it, when he had crept inside. She listened. There was absolutely no sound at all now. She had heard a small bumping noise after Sooty's last cry, but she didn't know what it was.

  She suddenly put her head round the door of her father's room, and shone her torch again. She stared in surprise. The bed was empty. The room was empty. There was no one there at all! She flashed her torch all round.

  She opened the cupboard door fearfully. She looked under the bed. She was, in fact, extremely brave.

  At last she sank down on the window-seat, frightened and puzzled. Where was her father? Where was Sooty? Whatever had been happening here that night?

  Chapter Sixteen

  NEXT MORNING

  AS GEORGE sat by the window, on the very seat into which everyone had unaccountably disappeared, though she did not know it, she heard a faint sound from the passage.

  Quick as lightning the girl slipped under t
he bed. Someone was creeping down the long passage! George lay silently on the floor, lifting the valance a little to try and see who it was. What queer things were going on tonight!

  Someone came in at the door. Someone stopped there, as if to look and listen. Then the Someone crept over to the window-seat.

  George watched and listened, straining her eyes in the darkness. She dimly saw the Someone outlined against the grey square of the window. He was bent over the window-seat.

  He showed no light at all. But he made some curious little sounds. First came the sound of his fingers tapping about on the closed lid of the seat. Then came the clink of something metallic, and a very faint squeaking. George could not imagine what the man - if it was a man - was doing.

  For about five minutes the Someone worked away at his task in the darkness. Then, as quietly as he had come, he went away. George couldn't help thinking it was Block, though his outline against the dark-grey of the window was too dim to recognise. But he had once given a little cough exactly like Block so often gave. It must be Block! But whatever was he doing in her father's room at night, on the window-seat?

  George felt as if she was in a bad dream. The queerest things happened and kept on happening, and they didn't seem to make sense at all. Where was her father? Had he left his room and gone wandering over the house? Where was Sooty, and why had he called out? He wouldn't have shouted out like that, surely, if her father had been asleep in the room!

  George lay under the bed, shivering, for a little while longer. Then she rolled out softly and went out of the door. She crept down the long passage to the end. She opened the door there and peeped out. The whole house was in darkness. Little sounds came to George's ears - a window rattling faintly, the creak of some bit of furniture - but nothing else.

  She had only one thought in her mind, and that was to get to the boys' room and tell them the mysterious things that had happened. Soon she was across the landing, and had slipped through the door of Julian's bedroom. He and Dick were awake, of course, waiting for Sooty to come with Timmy and George.
