"Sure!" replied Wilkins. "I'm through with you, you miserable shell-gamers! The best thing for you is to hopen the old coal-box hover there and count hout what's left of that ten thousand."

"Curse you!" hissed Summerdale. "How do we know you won't have us pinched whether we pay up or not?"

"I reckon we'd better take a chance," muttered the Colonel, laying down his revolver and dropping on his knees before the safe. The little knob spun around, the lock clicked, and the heavy door swung open, but at the same moment there was a terrific crash of glass behind them.

"Excuse noise," exclaimed Conville, thrusting his face through the broken pane and covering Buncomb with a long black weapon. "Kindly keep your arms up, Colonel—and you too, Larry. How stout you've grown! Thank you! I was peekin' through the keyhole, and kinder thought this would be a good time to freeze on to what was in the safe without callin' in an expert."

The next instant he had unlocked the door with his other hand and snapped the handcuffs on Summerdale's uplifted wrist. While the detective was doing the same to the Colonel, McAllister caught sight of Wilkins's frightened glance, and gave a slight nod toward the door leading into the next room. Like a flash the valet had jumped through and closed and locked the door behind him. Another door banged. Conville sprang into the hall across the fragments of the shattered glass, with McAllister at his heels. They were just in time to see Wilkins leap into the room where the men were testing the fire-escape.

"Let me try it," said he, and swung himself calmly into the tube. For an instant he delayed his flight, with only his head remaining visible.

"Good-by, Mr. McAllister," he called over his shoulder, "and thank you kindly. I won't forget, sir."

At the same instant Conville bounded through the door and rushed to the window. As he reached the sash Wilkins let go, and plunged downwards. His descent was rapid, his position being discernible from the sagging of the canvas.

Barney started for the elevator in the hope of cutting off the valet's escape below, but he had miscalculated the force of gravitation. As McAllister reached the window he saw the little bulge that represented Wilkins slide gently to the bottom. There was a cheer from the bystanders as the convict stepped lightly to his feet. Then he turned for an instant, and, looking up at McAllister, waved his hand and disappeared among the crowd.
