'Golly! You gave me a scare, Dick!' he whispered. 'Well, did you see who it was and where he went?'
Dick told them of his queer experience. 'He simply went into Block's room and vanished,' he said. 'Is there any secret passage leading out of Block's room, Sooty?'
'No, none,' said Sooty. 'That wing is much newer than the rest of the house, and hasn't any secrets in at all. I simply can't imagine what happened to the man. How very queer! Who is he, and why does he come, and where on earth does he go?'
'We really must find out,' said Julian. 'It's such a mystery! Sooty, how did you know there was signalling going on from the tower?'
'Well, some time ago I found it out, quite by accident,' said Sooty. 'I couldn't sleep, and I went along to that funny little box-room place, and ferreted about for an old book I thought I'd seen there. And suddenly I looked up at the tower, and saw a light flashing there.'
'Funny,' said Dick.
'Well, I went along there at night a good many times after that, to see if I could see the signals again,' said Sooty, 'and at last I did. The first time I had seen them there was a good moon, and the second time there was, too. So, I thought, next time there's a moon, I'll creep along to that old box-room and see if the signaller is at work again. And sure enough he was!'
'Where does that window look out on, that we saw the light flashing from?' asked Julian, thoughtfully. 'The seaward side — or the landward?'
'Seaward,' said Sooty at once. 'There's something or someone out at sea that receives those signals. Goodness knows who.'
'Some kind of smugglers, I suppose,' said Dick. 'But it can't be anything to do with your father, Sooty. I say — let's go up into the tower, shall we? We might find something there — or see something.'
They went back to the spiral staircase and climbed up to the tower-room. It was dark, for the moon was behind a cloud. But it came out after a while, and the boys looked out of the seaward window.
There was no mist at all that night. They could see the flat marshes stretching away to the sea. They gazed down in silence. Then the moon went in and darkness covered the marsh.
Suddenly Julian clutched the others, making them jump. 'I can see something!' he whispered. 'Look beyond there. What is it?'
They all looked. It seemed like a tiny line of very small dots of light. They were so far away that it was difficult to see if they stayed still or moved. Then the moon came out again, flooding everywhere with silvery light, and the boys could not see anything except the moonshine.
But when the moon went in again, there was the line of tiny, pricking lights again! 'A bit nearer, surely!' whispered Sooty. 'Smugglers — coming over a secret path from the sea to Castaway Hill! Smugglers!'
Chapter Ten. TIMMY MAKES A NOISE
THE three girls were very excited the next day when the boys told them their adventure of the night before.
'Gracious!' said Anne, her eyes wide with surprise. 'Who can it be signalling like that? And wherever did he go to? Fancy him going into Block's room, with Block there in bed!'
'It's very peculiar,' said George. 'I wish you had come and told me and Anne.'
'There wasn't time — and anyway, we couldn't have Timmy about at night. He might have flown at the signaller,' said Dick.
'The man must have been signalling to the smugglers,' said Julian, thoughtfully. 'Let me see — probably they came over from France in a ship — came as near to the marsh as they could — waited for a signal to tell them that the coast was clear — probably the signal from the tower — and then waded across a path they knew through the marsh. Each man must have carried a torch to prevent himself from leaving the path and falling into the marsh. No doubt there was someone waiting to receive the goods they brought — someone at the edge of the marsh below the hill.'
'But who?' said Dick. 'It can't have been Mr Barling, who, Sooty says, is known to be a smuggler. Because the signal lights came from our house, not his. It's all very puzzling.'
'Well, we'll do our best to solve the mystery,' said George. 'There's some queer game going on in this very house, with or without your father's knowledge, Sooty. We'll keep a jolly good lookout and see if we can find out what it is.'
They were at breakfast alone, when they discussed the night's adventure. Block came in to see if they had finished at that moment. Anne did not notice him.
'What does Mr Barling smuggle?' she asked Sooty. Immediately she got a hard kick on her ankle, and stared in pain and surprise. 'Why did you…?' she began, and got another kick, harder still. Then she saw Block.
'But he's deaf,' she said. 'He can't hear anything we say.'
Block began to clear away, his face as usual showing no expression. Sooty glared at Anne. She was upset and cross, but said no more. She rubbed her bruised ankle hard. As soon as Block went out of the room she turned on Sooty.
'You mean thing! You hurt my ankle like anything! Why shouldn't I say things in front of Block? He's quite deaf!' said Anne, her face very red.
'I know he's supposed to be,' said Sooty. 'And I think he is. But I saw a funny look come over his face when you asked me what Mr Barling smuggled — almost as if he had heard what you said, and was surprised.'
'You imagined it!' said Anne, crossly, still rubbing her ankle. 'Anyway, don't kick me so hard again. A gentle push with your toe would have been enough. I won't talk in front of Block if you don't want me to, but it's quite plain he's as deaf as a post!'
'Yes, he's deaf all right,' said Dick. 'I dropped a plate off the table yesterday, by accident, just behind him, and it smashed to bits, if you remember. Well, he didn't jump or turn a hair, as he would have done if he could have heard.'
'All the same — I never trust Block, deaf or not,' said Sooty. 'I always feel he might read our lips or something. Deaf people can often do that, you know.'
They went off to take Timmy for his usual morning walk. Timmy was quite used to being shut in the laundry basket by now, and lowered into the pit. In fact, he always jumped straight into the basket as soon as the lid was opened, and lay down.
That morning they again met Block, who stared with great interest at the dog. He plainly recognised it as the same dog as before.
'There's Block,' said Julian, in a low voice. 'Don't drive Timmy off this time. We'll pretend he's a stray who always meets us each morning.'
So they let Timmy run round them, and when Block came up, they nodded to him, and made as if to go on their way. But the man stopped them.
'That dog seems to be a friend of yours,' he said, in his curious monotone of a voice.
'Oh yes. He goes with us each morning now,' said Julian, politely. 'He quite thinks he's our dog! Nice fellow, isn't he?'
Block stared at Timmy, who growled. 'Mind you do not bring that dog into the house,' said Block. 'If you do, Mr Lenoir will have him killed.'
Julian saw George's face beginning to turn red with fury. He spoke hurriedly. 'Why should we bring him to the house, Block? Don't be silly!'
Block, however, did not appear to hear. He gave Timmy a nasty look, and went on his way, occasionally turning round to look at the little company of children.
'Horrid fellow!' said George, angrily. 'How dare he say things like that?'
When they got back to Marybelle's bedroom that morning, they pulled Timmy up from the pit, and let him out of the basket. 'We'll put him into the secret passage as usual,' said George, 'and I'll put some biscuits in with him. I got some nice ones for him this morning, the sort he likes, all big and crunchy.'
