McAllister slowly adjusted his monocle, smiled affably, and sank comfortably into an armchair.
"Why, it's you, Baron, isn't it! How are you? Won't you have a little nip of something warm? No? A cigar, then. Here, Peter, bring the gentleman an Obsequio. Well, to what do I owe this honor?"
Conville glared at him enraged. However, he restrained his wrath. A wise detective never puts himself at a disadvantage by giving way to useless emotion. When Peter returned with the cigar, Barney took it mechanically and struck a match, meanwhile keeping one eye upon the door of the club.
"I suppose," he presently remarked, "you think you're smart. Well, you're mistaken. I had you wrong last night, I admit—that is, so far as your identity was concerned. You're a real high-roller, all right, but that ain't the whole thing, by a long shot. How would you like to wander down to Headquarters as an accomplice?"
A few chills played hide-and-seek around the base of the clubman's spine.
"Don't be an ass!" he finally managed to ejaculate.
"Oh, I can't connect you with the necklace! You're safe enough there," Barney continued. "But how about this little game right here in this club? You're aiding in the escape of a felon. That's felony. You know that yourself. Besides, when you locked me in the bath-room last night you assaulted an officer in the performance of his duty. I've got you dead to rights, see?"
McAllister laughed lightly.
"By jiminy!" he exclaimed, "I thought you were crazy all the time, and now I know it. What in thunder are you driving at?"
Conville knocked the ashes off his cigar impatiently.
