"I know--you can tell the name of the man whom you drove that morning from the corner of Orchard Street to Kensington High Street," replied Triffitt. "It may be important--it mayn't. You see, the police haven't been in any hurry to approach you, have they? Come now, give it a name?" The informant summoned up his resolution. "Cash down--on the spot, guv'nor?" he asked. "Spot cash," replied Triffitt. "On this table!" "Well--how would a couple o' fivers be, now?" asked the anxious one. "It's good stuff, guv'nor." "A couple of fivers will do," answered Triffitt. "And here they are." He took two brand-new, crackling five-pound notes from his pocket, folded them up, laid them on the table, and set a glass on them. "Now, then!" he said. "Tell your tale--there's your money when it's told." The taxi-cab driver eyed the notes, edged his chair further into the half-lighted corner in which Triffitt and Carver sat, and dropped his voice to a whisper. "All right, guv'nor," he said. "Thanking you. Then it's this here--the man what I drove that morning was the nephew!" "You mean Mr. Barthorpe Herapath?" said Triffitt, also in a whisper. "That's him--that's the identical, sir!

And then, of course, I knew it was him as I took up at two o'clock that morning." "How did you know?" asked Triffitt. The taxi-cab driver held up a hand and tapped a brass ring on its third finger. "Where I wears that ring, gentlemen," he said triumphantly, "he wears a fine diamond--a reg'lar swell 'un. That morning, when he got into my cab, he rested his hand a minute on the door, and the light from one o' the lamps across the street shone full on the stone. Now, then, when this here Barthorpe was pointed out to me in Orchard Street, a few days ago, as the nephew of Jacob Herapath, he was talking to another gentleman, and as they stood there he lighted a cigar, and when he put his hand up, I see that ring again--no mistaking it, guv'nor! He was the man. And, from what I've read, it seems to me it was him as put on his uncle's coat and hat after the old chap was settled, and----"
