He was right, but be overstated the case in calling himself a tough.
Dave Doyle had been born among them and brought up among them, but he never was a tough himself, but a thoroughly honest fellow from the word go.
When I intimated that he was not the man for the sewer-gang job, on account of his relationship with the leader, he resolved to show me that he was the man, and he did.
Dave succeeded without an effort where Sam, with all his efforts, failed, and came within an ace of losing his life.
Therefore, I say, every one to his place.
But Sam Kean made a splendid detective. I used him as my society man for years, until he went off at last on his own hook.
So also with Dave. He remained my man for the work in the slums and a better one I never had.
Now then, boys, has all this taught you how to become a detective?
