"No, sir; but I guess Conklin does. This is how it is: It was my watch yesterday afternoon when Chatham came the first time. He went into the Manhattan Company's place through the basement at a quarter after five. So I just settled myself out here and waited. Well, I waited and waited, but there wasn't any sign of Chatham, and when Flagler came along to relieve me at ten o'clock Chatham hadn't come out yet. Flagler he spotted the place until six this morning, and then Conklin took his turn again until two o'clock, when I came on for my watch. Just as Conklin was telling me how things stood, who should come down the street but Chatham himself, large as life."

"Down the street?" exclaimed Sturgis.

"Yes, sir. And up he goes, as if nothing had happened, and into the Manhattan Chemical Company's place again."

"He had put up the back-door game on you," said the reporter.

"Yes, sir; just what I said to Conklin. So, quick as a wink, I sent him around the block to keep his eye peeled on the next street and I waited here. And here I've been ever since. If Conklin isn't on the block above, it must be because Chatham has made tracks again, and he after him."

"I'll go and find out," said Sturgis. "Has any one else called at the Manhattan Chemical Company's office since you have been on watch?"

"No, sir; but a couple of hours ago an express wagon came along and delivered a long wooden box; might have been chemicals for the wholesale department, for it was lowered to the cellar by the hoist in the areaway. The blond young man receipted for the box."

"Very well, Shrady. Hang on a little while longer, and I shall have you relieved just as soon as I possibly can."

So saying, the reporter, who had been pretending to look through his pockets for a coin, ostentatiously slipped a nickel into the outstretched palm before him. The light seemed to die out of the sharp eyes of the detective, and it was the miserable drunkard who staggered back to his place on the stoop next to the saloon, unmindful of the gibes of the young rowdies congregated there.

Sturgis walked up to the next street, where he found a second detective on duty.
