Parks ventured a word or two and presently led Detective Jones into a conversation. He was a highly educated man, and he had the gift of telling a story in an interesting fashion.

“By the way,” he said; “have you any objection to my smoking?”

“No; go ahead,” said Jones, pleasantly.

With his unfettered left hand Parks drew from his pocket a cigar case, fumbled with it a minute or two, and soon had a long, black weed between his teeth.

“Can I offer you a smoke?” he asked, hesitatingly.

The cigar case stopped on its way to his pocket, while he waited for the detective’s answer.

“Thanks. Don’t mind if I do.”

“Help yourself.

There was a peculiar gleam in his eyes as the detective struck a match and lit up.

Parks talked on pleasantly for a little while, but soon relapsed into silence as the train rushed on, carrying him nearer and nearer to Sing Sing.
