"I thought it might suit you to lock up your books and papers. That was all—till the day before yesterday. Then a ginger-haired sailor came in. North countryman. Wanted a ditty-box, he said. I told him we weren't marine outfitters, and he'd better try Barnard's, round the corner. He said he didn't want the ordinary sort, but something out of the common; extra large size; brass-bound; tray with a lock-up till. 'Mind if it was a trifle old?' I asked. 'Carved or cut about a bit? You know how some chaps use their knives on them, just to pass the time.' He said he didn't care for things that were hacked about, but he wouldn't object to a bit of poker-work on it. I told him I'd look through the warehouse and let him know in the morning, and he went. Byles, the dock policeman, was standing outside. I went and asked him who the chap was. He said he was cook on the Anne Traylor, just come in, and he believed he'd done time. If he hadn't I'll swear he ought to have, from the look of him.

"About half an hour afterward in walks an oldish chap with a stoop and a gray goat's beard. He wanted a ditty-box, too; something extra large and old, and strong, and a tray with a lock-up till in it. He was a fireman on the Anne Traylor, I found; a shifty sort of chap that couldn't look you in the face. He offered to go to a couple of pounds for the right thing. I told him I'd look through our stuff and let him know if we had one of the sort.

"Just as I was closing, a smart young fellow swaggered in. He was second mate of the Anne Traylor, and he'd heard of the death of her old captain on the Saucy Jane, and that we'd bought some of his effects, and he'd like to have a memento; just a matter of sentiment, he explained. I asked him what form the sentiment took, and he said a ditty-box; and if we had the one that belonged to the old man he'd give two pounds five for it. I put him off like the others.

"Two Swedish sailors came in after the shutters were up, while the door was still open. They wanted a ditty-box of the identical description. I told them I'd look for it, same as I told the rest. You always brought me up not to close too soon with a customer who was keen on a thing."

"Very good, Isaac," I said. "Very good! Go on!"

"In the evening I made inquiries at the 'Duke of Wellington,' where the dock policemen go, and the two-penny-halfpenny money lenders and such; and old Mrs. Higgins, the landlady, knows more about the crews that come here than anyone. Lots of them knew old Markby, it seemed; a very respectable old chap and a favorite with his men, but a bit of a miser, and a trifle queer in his ways. He boasted that he didn't believe in banks and such things, and he'd got his money hidden where even his wife didn't know. And the conclusion I've come to is that those chaps believe it's in the ditty-box, and they mean to have it."

"Ah!" I said. "We'll have something to say to that, Isaac! You told them we hadn't got it, of course."

"Of course," he said; "and of course they didn't believe me! I had a rare bother with the ginger-haired man yesterday morning, and had to send the boy for a policeman before he'd go. And in the afternoon the Swedes tried to sneak through the shop into the warehouse, but I jumped out of the shop parlor and hustled them off. I've put longer screws in the bars to the windows; but I'd be easier if you'd let me sleep here."

Isaac always thought that he could look after me better than I could look after myself!

"I'm all right, Isaac," I said; "but we'll have a look at the box before you go. It might be worth a bit more if it had a secret drawer, eh?"
