"I remember when he used to step into the ring," said Lord Ronsdale, his voice rising somewhat. "Truth is, sight of you brought back old recollections. Things I haven't thought of for a long time, don't you see!"

"Quite so! Delighted, I am sure. I didn't know so much about him then; that came after; except that the gentlemen found him a figure worth looking at when he got up at the post--"

"Yes; he was worth looking at." Lord Bonsdale's eyes half closed. "A heavy-fisted, shapely brute; with muscles like steel. But ignorant--" He lingered on the word; then his glance suddenly lifted--"Had something on his arm; recall noticing it while the bout was on!"

Mr. Gillett with a knowing expression rose, took a volume from a bookcase and opened it.

"The 'something' you speak of, my Lord," he observed proudly, "should be here; I will show it that you may appreciate my system; the method I have of gathering and tabulating data. You will find an encyclopedia of information in that bookcase. All that Scotland Yard has, and perhaps a little besides."

"Really?" The nobleman's eyes fastened themselves on the book.

"To illustrate: Here's his case." Gillett's fingers moved lightly over the page. "'Testimony of Dandy Joe, down-stairs at the time with landlady who kept the house where the crime was committed. Heard 'Frisco Pet, who had been drinking, come in; go up-stairs, as they supposed, to his own room; shortly after, loud voices; pistol shot. Landlady and Joe found woman, Amy Gerard, dead in shabby little sitting-room. Pet, the worse for liquor, in a dazed condition at a table, head in his hands. Testimony of Joe corroborated by landlady; she swore no one had been in house except parties here mentioned, all lodgers.

"'Private mem.--House in bad neighborhood, near the Adelphi catacombs. Son of landlady, red-headed giant, also one-time prize-fighter, used to live here; the Pet's last fight in the ring was with him. Later Tom took to the road; was wanted by the police at the time of the crime for some brutal highway work--' But," breaking off, "I am wearying your lordship. Here is what I was especially looking for, the markings on the arm of the 'Frisco Pet. Perhaps, however, your lordship doesn't care to listen further--"

"Go on!" The words broke sharply from the visitor's lips; then he gave a metallic laugh. "I am interested in this wonderful system of yours."

Mr. Gillett read slowly: "'On the right arm of the 'Frisco Pet, just below the elbow, appears the figure of a man, in sparring attitude, done in sailor's tattooing; about the waist a flag, the stars and stripes in their accustomed colors; crudely drawn but not to be mistaken by noting following defects and details--' which," closing the book, "I won't read."
