Cardona placed the two pasteboard boxes on the desk. Biscayne picked them up and noticed the attached labels: one with the word, “Tuxedo”; the other marked, “Business Suit.”

“What do you make of these?” Biscayne asked.

“To-day,” Cardona resumed, “I talked to Glenn’s valet. I found out that Louis Glenn was very careless about leaving things in his pockets.

“He never removed an article from a suit when he took it off. He paid no attention to his clothes. Placing them on a hanger, seeing that they were kept in press — that was the valet’s job.

“I talked with two men who were with Glenn, at the Merrimac Club, before the dinner.

“They state that he came in with them, changed suits in his room and went directly to dinner. One remembers that he reached in his pocket for a cigarette, on the way downstairs.

“That means that this box of cigarettes — the one that is marked, ‘Tuxedo’ — was in Glenn’s pocket when he put on the suit.

“Glenn was poisoned, by a poison that worked powerfully and swiftly, once it started to act.

“Suppose that the box of cigarettes was planted there. One cigarette, only, dipped in poison, and that cigarette replaced somewhere on the bottom row.

“Glenn, I understand, smoked not more than ten cigarettes in the course of an evening. The taxi driver seems to remember Glenn lighting a cigarette in the cab.
