But only George arrived. A scared George, with a very curious story to tell. She wrapped herself in the eiderdown on Julian's bed, and told what had happened, in whispers.

  They were amazed. Uncle Quentin gone! Sooty disappeared! Someone creeping into the room and fiddling about on the window-seat! What did it all mean?

  'We'll come to Uncle Quentin's room with you, straight away now,' said Julian, pulling on a dressing-gown, and hunting about for his slippers. 'I've got a feeling that things are getting pretty serious.'

  They all padded off to the other rooms. They went into Marybelle's room and woke her and Anne. Both little girls felt scared. Soon all five children were in the next room, from which George's father and Sooty had so strangely vanished.

  Julian shut the door, drew the curtains and switched on the light. At once they all felt better. It was so horrid to grope about in the dark with torches.

  They looked round the silent room. There was nothing there to show them how the others had disappeared. The bed was crumpled and empty. On the floor lay Sooty's torch, where it had fallen.

  George repeated again what she had thought she had heard Sooty call out, but it made no sense to anyone. 'Why call out Mr Barling's name, when there was only your father in the room?' said Julian. 'Surely Mr Barling wasn't hiding here - that would be nonsense. He had nothing to do with your father, George.'

  'I know. But I'm sure it was Mr Barling's name that I heard Sooty call out,' said George. 'Do you think - oh yes, do you think Mr Barling could possibly have crept through the secret opening in the cupboard, meaning to do some dirty work or other - and have gone back the same way, taking the others with him because they discovered him?'

  This seemed a likely explanation, though not a very good one. They all went to the cupboard and opened it. They groped between the clothes for the secret opening. But the little iron handle set there to pull on the stone at the back, was gone! Someone had removed it - and now the secret passage could not be entered, for there was no way of opening it just there!

  'Look at that!' said Julian in astonishment. 'Someone's been tampering with that too. No, George, the midnight visitor, whoever he was, didn't go back that way.'

  George looked pale. She had been hoping to go and fetch Timmy, by slipping through the secret opening in the cupboard. Now she couldn't. She longed for Timmy with all her heart, and felt that if only the big faithful dog were with her things would seem much brighter.

  'I'm sure Mr Lenoir is at the bottom of all this!' said Dick. 'And Block too. I bet that was Block you saw in here tonight, doing something in the dark, George. I bet he and Mr Lenoir are hand in glove with each other over something.'

  'Well, then - we can't possibly go and tell them what has happened!' said Julian. 'If they are at the bottom of all these queer happenings it would be foolish to go and tell them what we know. And we can't tell your mother, Marybelle, because she would naturally go to your father about it. It's a puzzle to know what to do!'

  Anne began to cry. Marybelle, frightened and puzzled, at once began to sob too. George felt tears pricking the backs of her eyelids, but she blinked them away. George never cried!

  ‘I want Sooty,' wept Marybelle, who adored her cheeky, daring brother. 'Where's he gone? I'm sure he's in danger. I do want Sooty.'

  'We'll rescue him tomorrow, don't you worry,' said Julian, kindly. 'We can't do anything tonight, though. There's nobody at Smuggler's Top we can possibly get advice or help from, as things are. I vote we go to bed, sleep on it, and make plans in the morning. By that time Sooty and Uncle Quentin may have turned up again. If they haven't, Mr Lenoir will have to be told by someone, and we'll see how he behaves! If he's surprised and upset, we'll soon know if he has had anything to do with this mystery or not. He'll have to do something - go to the police, or have the house turned upside down to find the missing people. We'll soon see what happens.'

  Everyone felt a little comforted after this long speech. Julian sounded cheerful and firm, though he didn't feel at all happy, really. He knew, better than any of the others, that something very strange, and probably dangerous, was going on at Smuggler's Top. He wished the girls were not there.

  'Now listen,' he said. 'George, you go and sleep with Anne and Marybelle next door. Lock your door and keep the light on. Dick and I will sleep here, in Sooty's old room, also with the light on, so you'll know we are quite nearby.'

  It was comforting to know that the two boys were so near. The three girls went at last into Marybelle's room, tired out. Anne and Marybelle got into bed again, and George lay down on a small but comfortable couch, pulling a thick rug over her. In spite of all the worry and excitement the girls were asleep in a half a minute, quite exhausted.

  The boys talked a little, as they lay in Sooty's old bed, where their Uncle Quentin had been asleep some time before. Julian did not think anything more would happen that night. He and Dick fell asleep, but Julian was ready to wake at the slightest noise.

  Next morning they were awakened by a most surprised Sarah, who had come in to draw the curtains and bring George's father a pot of early-morning tea. She could not believe her eyes when she saw the two boys in the visitor's bed - and no visitor!

  'What's all this?' said Sarah, gaping. 'Where's your uncle? Why are you here?'

  'Oh, we'll explain later,' said Julian, who did not want to enter into any details with Sarah, who was a bit of a chatterbox. 'You can leave the tea, Sarah. We'd like it!'

  'Yes, but where's your uncle? Is he in your room?' said the puzzled Sarah. 'What's up?'

  'You can go and look in our room if you like and see if he's there,' said Dick, wanting to get rid of the amazed woman. She disappeared, thinking that the household must be going mad. She left the hot tea behind, though, and the boys at once took it into the girls' room. George unlocked the door for them. They took it in turns to sip the hot tea from the one cup.

  Presently Sarah came back, with Harriet and Block. Block's face was as blank as usual.

  'There's nobody in your room, Master Julian,' began Sarah. Then Block gave a sudden exclamation and stared at George angrily. He had thought she was locked in her room - and here she was in Marybelle's room, drinking tea!

  'How did you get out?' he demanded. 'I'll tell Mr Lenoir. You're in disgrace.'

  'Shut up,' said Julian. 'Don't you dare to speak to my cousin like that. I believe you're mixed up in this curious business. Clear out, Block.'

  Whether Block heard or not, he gave no sign of going. Julian got up, his face set.

  'Clear out of this room,' he said, narrowing his eyes. 'Do you hear? I have a feeling that the police might be interested in you, Block. Now clear out!'

  Harriet and Sarah gave little shrieks. The sudden mystery was too much for them. They gazed at Block and began to back out of the room. Fortunately Block went too, casting an evil look at the determined Julian.

  'I shall go to Mr Lenoir,' said Block, and disappeared.

  In a few minutes along came Mr and Mrs Lenoir to Marybelle's room. Mrs Lenoir looked scared out of her life. Mr Lenoir looked puzzled and upset.

  'Now, what's all this?' he began. 'Block has been to me with a most curious tale. Says your father has disappeared, George, and...'

  'And so has Sooty,' suddenly wailed Marybelle, bursting into tears again. 'Sooty's gone. He's gone too.'

  Mrs Lenoir gave a cry. 'What do you mean? How can he have gone? Marybelle, what do you mean?'

  'Marybelle, I think I had better take charge of the telling,' said Julian, who was not going to let the little girl give away all the things they knew. After all, Mr Lenoir was probably at the bottom of everything, and it would be foolish to tell him what they suspected about him.

  'Julian - tell me what has happened. Quickly!' begged Mrs Lenoir, looking really upset.

  'Uncle Quentin disappeared from his bed last night, and Sooty has vanished too,' said Julian, shortly. 'They may turn up, of course.'

  'Julian! You are keeping back something,' said M
r Lenoir, suddenly, watching the boy sharply. 'You will tell us everything, please. How dare you keep anything back at a moment like this?'

  'Tell him Julian, tell him,' wailed Marybelle, Julian looked obstinate, and glared at Marybelle.

  The tip of Mr Lenoir's nose went white. 'I am going to the police,' he said. 'Perhaps you will talk to them, my boy. They will knock some sense into you!'

  Julian was surprised. 'Why - I shouldn't have thought you would want to go to the police!' he blurted out. 'You've got too many secrets to hide!'

  Chapter Seventeen

  MORE AND MORE PUZZLING

  MR LENOIR stared in the utmost amazement at Julian. There was a dead silence after this remark. Julian could have kicked himself for making it, but he couldn't unsay it now.

  Mr Lenoir opened his mouth to say something at last, when footsteps came to the door. It was Block.

  'Come in, Block!' said Mr Lenoir. 'There seem to have been queer happenings here.'

  Block did not appear to hear, and remained outside the door. Mr Lenoir beckoned him in impatiently.

  'No,' said Julian, firmly. 'What we have to say is not to be said in front of Block, Mr Lenoir. We don't like him and we don't trust him.'

  'What do you mean?' cried Mr Lenoir, angrily. 'What do you know about my servants? I've known Block for years before he came into my service, and he's a most trustworthy fellow. He can't help being deaf, and that makes him irritable at times.'

  Julian remained obstinate. He caught an angry gleam in Block's cold eyes, and glared back.

  'Well, this is incredible!' said Mr Lenoir, trying not to lose his temper. 'I can't think what's come over everybody - disappearing like this - and now you children talking to me as if I wasn't master in my own house. I insist that you tell me all you know.'

  'I'd rather tell it to the police,' said Julian, his eye on Block. But Block showed no trace of expression on his face.

  'Go away, Block,' said Mr Lenoir at last, seeing that there was no hope of getting anything out of Julian while the servant was there. 'You'd better all come down to my study. This is getting more and more mysterious. If the police have got to know, you may as well tell me first. I don't want to look a complete idiot in my own house in front of them.'

  Julian couldn't help feeling a bit puzzled. Mr Lenoir was not behaving as he had thought he might behave. He seemed sincerely puzzled and upset, and he was evidently planning to get the police in himself. Surely he wouldn't do that if he had had a hand in the disappearances? Julian was lost in bewilderment again.

  Mrs Lenoir was now crying quietly, with Marybelle sobbing beside her. Mr Lenoir put an arm round his wife and kissed Marybelle, suddenly appearing very much nicer than he had ever seemed before. 'Don't worry,' he said, in a gentle voice. 'We'll soon get to the bottom of this, if I have to get the whole of the police force in. I think I know who's at the bottom of it all!'

  That surprised Julian even more. He and the others followed Mr Lenoir down to his study. It was still locked. Mr Lenoir opened it and pushed aside a great pile of papers that were on his desk.

  'Now - what do you know?' he said to Julian quietly. The children noticed that the top of his nose was no longer white. Evidently he had got over his burst of temper.

  'Well, sir - I think this is a queer house, with a lot of queer things happening in it,' said Julian, not quite knowing how to begin. 'I'm afraid, sir, you won't like me telling the police all I know.'

  'Julian, don't speak in riddles!' said Mr Lenoir, impatiently. 'You act as if I were a criminal, in fear of the police. I'm not. What goes on in this house?'

  'Well - the signalling from the tower, for instance,' said Julian, watching Mr Lenoir's face.

  Mr Lenoir gaped. It was clear that he was immensely astonished. He stared at Julian, and Mrs Lenoir cried out suddenly:

  'Signalling! What signalling?'

  Julian explained. He told how Sooty had discovered the light-flashing first, and then how he and Dick had gone with him to the tower when they had seen the flashing again. He described the line of tiny, pricking lights across the marsh from the seaward side.

  Mr Lenoir listened intently. He asked questions about dates and times. He heard how the boys had followed the signaller to Block's room, where he had disappeared.

  'Got out of the window, I suppose,' said Mr Lenoir. 'Block's got nothing to do with this, you can rest assured of that. He is most faithful and loyal, and has been a great help to me while he has been here. I have an idea that Mr Barling is at the bottom of all this. He can't signal from his house to the sea because it's not quite high enough up the hill, and is in the wrong position. He must have been using my tower to signal from - coming himself to do it too! He knows all the secret ways of this house, better than I do! It would be easy for him to come here whenever he wanted to.'

  The children thought at once that probably Mr Barling had been the signaller! They stared at Mr Lenoir. They were all beginning to think that he really and truly had nothing to do with the queer goings-on after all.

  'I don't see why Block shouldn't know all this,' said Mr Lenoir, getting up. 'It's plain to me that Barling could explain a lot of the queer things that have been happening. I'll see if Block has ever suspected anything.'

  Julian pursed his lips together. If Mr Lenoir was going to tell everything to Block, who certainly must be in the plot somehow, he wasn't going to tell him anything more!

  I'll see what Block thinks about everything, and then if we can't solve this mystery ourselves, we'll get in the police,' said Mr Lenoir, going out of the room.

  Julian did not want to say anything much in front of Mrs Lenoir. So he changed the subject completely.

  'What about breakfast?' he said. 'I'm feeling hungry!'

  So they all went to have breakfast, though Marybelle could eat nothing at all, because she kept thinking of poor Sooty.

  'I think,' said Julian, when they were alone at the table, 'I rather think we'll do a little mystery-solving ourselves. I'd like a jolly good look round that room of your father's, George, to begin with. There must be some other way of getting out of there, besides the secret passage we know.'

  'What do you think happened there last night?' said Dick.

  'Well, I imagine that Sooty went there and hid, to wait until it was safe to try and get into the secret passage as soon as Uncle Quentin was asleep,' said Julian, thoughtfully. 'And while he was hiding, someone came into that room from somewhere, to kidnap Uncle Quentin. Why, I don't know, but that's what I think. Then Sooty yelled out in surprise, and got knocked on the head or something. Then he and Uncle Quentin were kidnapped together, and taken off through some secret way we don't know.'

  'Yes,' said George. 'And it was Mr Barling who kidnapped them! I distinctly heard Sooty yell out "Mr Barling". He must have switched on his torch and seen him.'

  'They are quite probably hidden somewhere in Mr Barling's house, 'said Anne, suddenly.

  'Yes!' said Julian. 'Why didn't I think of that? Why, that's just where they would be, of course. I've a jolly good mind to go down and have a look!'

  'Oh, let me come too,' begged George.

  'No,' said Julian. 'Certainly not. This is rather a dangerous adventure, and Mr Barling is a bad and dangerous man. You and Marybelle are certainly not to come. I'll take Dick.'

  'You are absolutely mean!' began George, her eyes flashing. 'Aren't I as good as a boy? I'm going to come.'

  'Well, if you're as good as a boy, which I admit you are,' said Julian, 'can't you stay and keep an eye on Anne and Marybelle for us? We don't want them kidnapped too.'

  'Oh, don't go, George,' said Anne. 'Stay here with us.'

  'I think it's mad to go, anyhow,' said George, 'Mr Barling wouldn't let you in. And if you did get in you wouldn't be able to find all the secret places in his house. There must be as many, and more, as there are here.'

  Julian couldn't help thinking George was right. Still, it was worth trying.

  He and Dick set out after breakfas
t, and went down the hill to Mr Barling's. But when they got there they found the whole house shut up. Nobody answered their knocking and ringing. The curtains were drawn across the closed windows, and no smoke came from the chimney.

  'Mr Barling's gone away for a holiday,' said the gardener who was working in the next door flower-beds. 'Went this morning, he did. In his car. All his servants have got a holiday too.'

  'Oh!' said Julian, blankly. 'Was there anyone with him in the car - a man and a boy, for instance?'

  The gardener looked surprised at this question, and shook his head.

  'No. He was alone, and drove off himself.'

  'Thanks,' said Julian, and walked back with Dick to Smuggler's Top. This was queer. Mr Barling had shut up the house and gone off without his captives! Then what had he done with them? And why on earth had he kidnapped Uncle Quentin? Julian remembered that Mr Lenoir had not put forward any reason for that. Did he know one, and hadn't wanted to say what it was? It was all most puzzling.

  Meantime George had been doing a little snooping round on her own. She had slipped into Uncle Quentin's room, and had had a really good look round everywhere to see if by chance there was another secret passage Sooty hadn't known about.

  She had tapped the walls. She had turned back the carpet and examined every inch of the floor. She had tried the cupboard again, and wished she could get through into the secret passage there and find Timmy. The study door downstairs was again locked, and she did not dare to tell Mr Lenoir about Timmy and ask his help.

  George was just about to leave the quiet room when she noticed something on the floor near the window. She bent to pick it up. It was a small screw. She looked round. Where had it come from?

  At first she couldn't see any screws of the same size at all. Then her eyes slid down to the window-seat. There were screws there, screwing down the top oaken plank to the under ones that supported it.
