"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 Dave felt sure that, however much she might try to conceal it, Robert Ashford would perceive, by her looks, that something was wrong.

Nellie was told a day or two later, for, although ignorant of her father's nightly watchings, she was conscious from his manner, and that of her mother, that something was amiss, and was so persistent in her inquiries, that the Captain consented to her mother telling her that he had a suspicion he was being robbed, and warning her that it was essential that the subject must not be in any way alluded to.

"Your father is worrying over it a good deal, Nellie, and it is better that he should not perceive that you are aware of it. Just let things go on as they were."

"Is the loss serious, mother?"

"Yes; he thinks that a good deal of money has gone. I don't think he minds that so much as the fact that, so far, he doesn't know who the people most concerned in it may be. He has some sort of suspicion in one quarter, but has no clue whatever to the men most to blame."
