"Captain Dave," he said, in a low voice, "get up at once, and please don't make a noise."
"Ay, ay, lad."
There was a movement from the bed, and a moment later the Captain stood beside him.
"What is it, lad?" he whispered.
"There are two figures moving along on the ridge of the roof of the warehouse. I think it is the apprentices. I heard a slight noise, as if they were letting themselves down from their window by a rope. It is just over that roof, you know."
There was a rustling sound as the Captain slipped his doublet on.
"That is so. The young scoundrels! What can they be doing on the roof?"
They went to the window behind. Just as they reached it there was a vivid flash of lightning. It sufficed to show them a figure lying at full length at the farther end of the roof; then all was dark again, and a second or two later came a sharp, crashing roar of thunder.
"We had better stand well back from the window," Cyril whispered. "Another flash might show us to anyone looking this way."
"What does it mean, lad? What on earth is that boy doing there? I could not see which it was."
"I think it is Ashford," Cyril said. "The figure in front seemed the smaller of the two."
"But where on earth can Tom have got to?"
"I should fancy, sir, that Robert has lowered him so that he can get his feet on the crane and swing it outwards; then he might sit down on it and swing himself by the rope into the loft if the doors are not fastened inside. Robert, being taller, would have no difficulty in lowering himself—There!" he broke off, as another flash of lightning lit up the sky. "He has gone, now; there is no one on the roof."
John Wilkes was by this time standing beside them, having started up at the first flash of lightning.
"Do you go up, John, into their room," the Captain said. "I think there can be no doubt that these fellows on the roof are Ashford and Frost, but it is as well to be able to swear to it."
The foreman returned in a minute or two.
"The room is empty, Captain; the window is open, and there is a rope hanging down from it. Shall I cast it adrift?"
"Certainly not, John. We do not mean to take them tonight, and they must be allowed to go back to their beds without a suspicion that they have been watched. I hope and trust that it is not so bad as it looks, and that the boys have only broken out from devilry. You know, boys will do things of that sort just because it is forbidden."
"There must be more than that," John Wilkes said. "If it had been just after they went to their rooms, it might be that they went to some tavern or other low resort, but the town is all asleep now."
They again went close to the window, pushed the casement a little more open, and stood listening there. In two or three minutes there was a very slight sound heard.
"They are unbolting the door into the yard," John Wilkes whispered. "I would give a month's pay to be behind them with a rope's end."
Half a minute later there was a sudden gleam of light below, and they could see the door open. The light disappeared again, but they heard footsteps; then they saw the light thrown on the fastening to the outer gate, and could make out that two figures below were applying a key to the padlock. This was taken off and laid down; then the heavy wooden bar was lifted, and also laid on the ground. The gate opened as if pushed from the other side. The two figures went out; the sound of a low murmur of conversation could be heard; then they returned, the gate was closed and fastened again, they entered the warehouse, the light disappeared, and the door was closed.
"That's how the things went, John."
"Ay, ay, sir," the foreman growled.
"As they were undoing the gate, the light fell on a coil of rope they had set down there, and a bag which I guess had copper of some kind in it. They have done us cleverly, the young villains! There was not noise enough to wake a cat. They must have had every bolt and hinge well oiled."
"We had better close the casement now, sir, for as they come back along the ridge they will be facing it, and if a flash of lightning came they would see that it was half open, and even if they did not catch sight of our faces they would think it suspicious that the window should be open, and it might put them on their guard."
"Yes; and we may as well turn in at once, John. Like enough when they get back they will listen for a bit at their door, so as to make sure that everything is quiet before they turn in. There is nothing more to see now. Of course they will get in as they got out. You had better turn in as you are, Cyril; they may listen at your door."
Cyril at once went up to his room, closed the door, placed a chair against it, and then lay down on his bed. He listened intently, and four or five minutes later thought that he heard a door open; but he could not be sure, for just at that moment heavy drops began to patter down upon the tiles. The noise rose louder and louder until he could scarce have heard himself speak. Then there was a bright flash and the deep rumble of the thunder mingled with the sharp rattle of the raindrops overhead. He listened for a time to the storm, and then dropped off to sleep.
Things went on as usual at breakfast the next morning. During the meal, Captain Dave gave the foreman several instructions as to the morning's work.
"I am going on board the Royalist," he said. "John Browning wants me to overhaul all the gear, and see what will do for another voyage or two, and what must be new. His skipper asked for new running rigging all over, but he thinks that there can't be any occasion for its all being renewed. I don't expect I shall be in till dinner-time, so anyone that wants to see me must come again in the afternoon."
Ten minutes later, Cyril went out, on his way to his work. Captain Dave was standing a few doors away.
"Before I go on board the brig, lad, I am going up to the Chief Constable's to arrange about this business. I want to get four men of the watch. Of course, it may be some nights before this is tried again, so I shall have the men stowed away in the kitchen. Then we must keep watch, and as soon as we see those young villains on the roof, we will let the men out at the front door. Two will post themselves this end of the lane, and two go round into Leadenhall Street and station themselves at the other end. When the boys go out after supper we will unlock the door at the bottom of the stairs into the shop, and the door into the warehouse. Then we will steal down into the shop and listen there until we hear them open the door into the yard, and then go into the warehouse and be ready to make a rush out as soon as they get the gate open. John will have his boatswain's whistle ready, and will give the signal. That will bring the watch up, so they will be caught in a trap."
"I should think that would be a very good plan, Captain Dave, though I wish that it could have been done without Tom Frost being taken. He is a timid sort of boy, and I have no doubt that he has been entirely under the thumb of Robert."
"Well, if he has he will get off lightly," the Captain said. "Even if a boy is a timid boy, he knows what will be the consequences if he is caught robbing his master. Cowardice is no excuse for crime, lad. The boys have always been well treated, and though I dare say Ashford is the worst of the two, if the other had been honest he would not have seen him robbing me without letting me know."
For six nights watch was kept without success. Every evening, when the family and apprentices had retired to rest, John Wilkes went quietly downstairs and admitted the four constables, letting them out in the morning before anyone was astir. Mrs. Dowsett had been taken into her husband's confidence so far as to know that he had discovered he had been robbed, and was keeping a watch for the thieves. She was not told that the apprentices were concerned in the matter, for Captain
