'What yer goin' to do?'
'I can't say, my boy.'
'Well, I'll tell you. Know what Sagacious done?'
'Sagacious? Who is he?'
'Sam Sagacious—Sleuth-hound Sam.'
Harry looked puzzled.
'What, don't you know Sleuth-hound Sam? He's a great feller in a book, what tracks down criminals. Listen here. One time a chap what was a mate of his got put in gaol for stealin' money from a bank where he worked, when it wasn't him at all. Sam, he went an' got a job at the same bank, and that's how he found out the coves 'at done it.'
The young man turned upon Dick, and sat for a moment following up the inference. Then he gripped the latter's hand.
'By thunder!' he cried excitedly, 'that's a better idea than I could hit on in a week.'
Dick did not doubt it; he had but a poor opinion of the resourcefulness of his elders when not figuring in the pages of romantic literature, but he was gratified by Harry's ready recognition of his talent, and proceeded to enlarge upon the peculiar qualities of Sleuth-hound Sam, give instances of his methods, and relate some of his many successes.
