“He said if I didn't return in half an hour with the cash box, he'd notify the police.”

“Oh, ho!” The man's lips widened in a grin under the edge of his mask. “So he's going to wait here, eh? Well, so much the better! It'll save us a trip to his house. Now, see here, Calhoun, let this sink in!” He put his hand in his pocket and drew out a slip of paper. “Here's your note. It was on the desk where Kirschell was writing on it, and I pinched it when I pinched the cash box. We didn't figure we were going to make the haul we did to-night—we were after you. But there's some money in that cash box, as you saw for yourself. Here's the idea: Kirschell's read a thing or two about what's going on around here—enough to make him know that there ain't much our gang'll stop at. If you say you're with us, me and my pal 'll go in there and throw the fear of God into him. Do you get it? He'll think himself lucky to get off by keeping his mouth shut about to-night when he finds out who he's up against. Also you get the note back, and a share of the cash—and more to come later on.”

“No!” Calhoun cried out. “No! I'm no thief!”

“All right!” agreed the other indifferently.

“That's one side of it. Here's the other: Kirschell certainly believes you took it. He's a shark all right, and he thinks more of his money than he does of anything else, or he wouldn't have given you the chance he did. But when you don't show back there with the coin, he'll take the only other hope he's got of getting his money and turn on the police tap—see? What are you going to do then? Make a break for it, or let 'em get you? Well, it doesn't matter which. This note and a chunk of the cash gets mailed to-night—and the police get tipped off to watch your mail in the morning. Kind of reasonable, isn't it? Your pal, not being able to find you, and not tumbling to the fact that the police have got you until too late, comes across with your share like an honest little man! I think you said something about proof, Calhoun? And I think I told you before that we didn't do things by halves. How about that on top of Kirschell's story—do you think it would cinch a jury, or do you think they'd believe any little fairy story you might tell them, say, about meeting me? Does it look any more like twenty years than it did?”

There was a sudden agony in Calhoun's face.

“My God!” he whispered. “You—you wouldn't do that?”

The man made no answer. He still held the note-in his hand—but in the other now he carelessly dangled a revolver.

“You wouldn't! You wouldn't!” Calhoun's voice was broken now. “I've a wife and children, and—my God, what am I to do!”

“That half-hour Kirschell gave you is slipping along,” suggested the other uncompromisingly. “Here's the note, and there's easy money waiting for you.”
