“Oh, no,” said Kirschell. “I can see you haven't. I don't even know which of you two struck me. But I do know that you and the man who has my cash box worked up this plant together.”

Calhoun stepped forward threateningly—only to retreat again before the lifted muzzle of the revolver.

“You're a fool!” he snarled. “You've nothing on me!”

“That's for the police to decide,” returned Kirschell evenly. “It would have been a pleasant way of disposing of that note, wouldn't it—if you hadn't under-rated me! And your pal for his share, I daresay, was to take his chance on whatever there might be in the cash box! Why did you say you couldn't come until night, when I gave you until to-day as the last day in which to settle? Why did you insist on my indorsing the payment on the note, which necessitated my opening the safe and taking out the cash box in which you knew the note was kept, for you saw me put it there a week ago, when you first came here? And just after I was knocked down I heard your accomplice whisper: 'All right, I've got it.

“It's possible the police might form the same opinion I have as to whom those words were addressed!” Calhoun's face had grown whiter.

“It's a lie!” he said scarcely above a whisper. “It's a lie! I had nothing to do with it!”

“I want my three thousand dollars!” Kirschell's lips were set. He held a red-stained handkerchief to his cheek. “If I call the police now they'll get you—but it's your accomplice that's got my money. And it's my money that I want! I'll give you half an hour to go to him, and bring the money back here—and leave the police out of it. If you're not here in that time, I put it up to the police. Half an hour is time enough for you to find your pal; and it's not time enough for you to attempt to leave the city—and get very far!” Kirschell laid his watch on the desk. “You'd better go—I mean half an hour from now.”

Calhoun hung hesitant for a moment, staring at the muzzle of Kirschell's revolver. He made as though to say something—and instead, abruptly, with a short, jarring laugh, turned on his heel, and passed out of the room.

The Hawk was already edging his way along the wall toward the corridor door.

“Three thousand dollars!”—the Hawk rolled the words like so many dainty morsels on his tongue, as he communed with himself. “I guess it's my play to stick to Mr. Calhoun!”
