After a long time they came out on the edge of the marsh itself, at the bottom of the hill! It was a desolate place, and the mists were over it, so that neither Sooty nor Uncle Quentin knew which way to turn!
'Never mind,' said Sooty, 'we can easily leave it to Timmy. He knows the way all right. He'll take us back to the town, and once there we'll know the way home ourselves!'
But suddenly, to their surprise and dismay, Timmy stopped dead, pricked up his ears, whined and would go no farther. He looked thoroughly miserable and unhappy. What could be the matter?
Then, with a bark, the big dog left the two by themselves, and galloped back into the tunnel they had just left. He disappeared completely!
'Timmy!' yelled Sooty. 'Timmy! Come here! Don't leave us! TIMMY!'
But Timmy was gone; why, neither Sooty nor Uncle Quentin knew. They stared at one another.
'Well — I suppose we'd better try to make our way over this marshy bit,' said Uncle Quentin, doubtfully, putting a foot out to see if the ground was hard. It wasn't! He drew back his foot at once.
The mists were so thick that it was really impossible to see anything. Behind them was the opening to the tunnel. A steep rocky cliff rose up above it. There was no path that way, it was certain. Somehow they had to make their way round the foot of the hill to the main-road that entered the town — but the way lay over marshy ground!
'Let's sit down and wait for a bit to see if Timmy comes back,' said Sooty. So they sat down on a rock at the entrance to the tunnel and waited.
Sooty began to think of the others. He wondered what they had thought when they had discovered that both he and Uncle Quentin were missing. How astonished they must have been!
'I wonder what the others are doing?' he said, aloud. 'I'd love to know!'
The others, as we know, had been doing plenty. They had found the opening in the window-seat where Mr Barling had taken the captives, and they had gone down it and actually seen Mr Barling and Block on their way to talk to Uncle Quentin and Sooty!
They had found out, too, that Block hadn't been in his bed — he had left a dummy there instead. Now everyone was talking at once, and Mr Lenoir was suddenly convinced that Block had been a spy, put in his house by Mr Barling, and not the good servant he had appeared!
Once Julian felt that he was convinced of this he spoke to him more freely, and told him of the way through the window-seat, and of how they had seen Mr Barling and Block that very day, in the underground tunnels!
'Good heavens!' said Mr Lenoir, now looking thoroughly alarmed. 'Barling must be mad! I've always thought he was a bit queer — but he must be absolutely mad to kidnap people like this — and Block must be, too. This is a plot! They've heard what I've been planning with your uncle — and they've made up their minds to stop it because it will interfere with their smuggling. Goodness knows what they'll do now! This is serious!'
'If only we had Timmy!' suddenly said George.
Mr Lenoir looked astonished.
'Who's Timmy?'
'Well, you might as well know everything now,' said Julian, and he told Mr Lenoir about Timmy, and how they had hidden him.
'Very foolish of you,' said Mr Lenoir, shortly, looking displeased. 'If you'd told me I would have had someone in the town look after him. I can't help not liking dogs. I detest them, and never will have them in the house. But I would willingly have arranged for him to be boarded out, if I'd known you'd brought him.'
The children felt sorry and a little ashamed. Mr Lenoir was a queer, hot-tempered person, but he didn't seem nearly as horrid as they had thought he was.
'I'd like to go and see if I can find Timmy,' said George. 'You'll get the police in now, I suppose, Mr Lenoir, and perhaps we could go and find Timmy? We know the way into the secret passage from your study.'
'Oh — so that's why you were hiding there in the afternoon yesterday,' said Mr Lenoir. 'I thought you were a very bad boy. Well, go and try and find him if you like, but don't let him come anywhere near me. I really cannot bear dogs in the house.'
He went to telephone the police-station again. Mrs Lenoir, her eyes red with crying, stood by him. George slipped away to the study, followed by Dick and Julian and Anne. Marybelle stayed beside her mother.
'Come on — let's get into that secret passage and try to find old Timmy,' said George. 'If we all go, and whistle and shout and call, he's sure to hear us!'
They found the way into the passage, by doing the things they had done before. The panel slid back, and then another, larger opening came as before. They all squeezed through it, and found themselves in the very narrow passage that led from the study up to Sooty's bedroom.
But Timmy was not there! The children were surprised, but George soon thought why.
'Do you remember Sooty telling us there was a way into this passage from the dining-room, as well as from the study and Sooty's bedroom? Well, I believe I saw a door or something there, as we passed where the dining-room must be, and it's likely Timmy may have pushed through it, and gone into another passage somewhere.'
They went back, one by one. They came to the dining-room — or rather, they walked behind the dining-room wall. There they saw the door that George had noticed as they passed — a door, small and set quite flat to the wall, so that it was difficult to see. George pushed it. It opened easily, and then flapped shut, with a little click. It could be opened from one side but not from the other.
'That's where Timmy's gone!' said George, and she pushed the door open again. 'He pushed against the door and it opened — he went through, and the door fastened itself so that he couldn't get back. Come on, we must find him.'
They all went through the small door. It was so low that they had to bend their heads to go through, even Anne. They found themselves in a passage rather like the one they had just left, but not quite so narrow. It suddenly began to go downwards. Julian called back to the others.
'I believe it goes down to the passages where we used to take Timmy when we let him down into that pit to go for a walk! Yes, look — we've come to where the pit itself is!'
They went on, calling Timmy, and whistling loudly, but no Timmy came. George began to feel worried.
'Hallo! — surely this is where we came out when we climbed down all those steps from the window-seat passage!' said Dick, suddenly. 'Yes, it is. Look, there's the tunnel where we saw Block and Mr Barling going!'
'Oh — do you think they've done something to Timmy?' said George, in a frightened voice. 'I never thought of that!'
Everyone felt alarmed. It was strange that Block and Mr Barling could go about unmolested by Timmy if Timmy was somewhere near! Could they have harmed him in any way? They had no idea that Timmy was at that very minute with George's father and Sooty!
'Look at this!' said Julian, suddenly, and he shone his torch on to something to show the others. 'String! String going right down this tunnel. Why?'
'It's the tunnel that Mr Barling and Block took!' said George. 'I believe it leads to where they've taken my father and Sooty! They're keeping them prisoners down here! I'm going to follow the string and find them! Who's coming with me?'
Chapter Twenty-one. A JOURNEY THROUGH THE HILL
'I'm coming!' said everyone at once. As if they would let George go alone!
So down the dark tunnel they went, feeling the string and following it. Julian ran it through his fingers, and the others followed behind, holding hands. It would not do for anyone to get lost.
