Carl shifted the lamp that its pale fan of light might fall full upon the other's face.
"Let me tell you--do!" said he. "For I'm sure I know. During the summer, my dear Kronberg, I was the victim of a series of peculiar and persistent attacks. To a growing habit of unremitting vigilance and suspicion, I may thank my life. As for the peaceful monotony of the last nine weeks, doubtless I may attribute that to the constant companionship of Wherry, the fact that you were much too unpopular with the Carmodys as a foreigner to find an opportunity of poisoning my food, and that I've fallen into the discreet and careful habit of always drinking from a fresh bottle, properly sealed. There was a chance even there, but you were not clever enough to take it. You're overcautious and a coward. But how busy you must have been before that," he purred solicitously, "bolting about in various disguises after me. How very patient! Dear, dear, if Nature had only given you brains enough to match your lack of scruples--"
The insolent purr of his musical voice whipped color into Kronberg's cheeks. Abruptly he shifted his position and glared stonily.
"Venice," murmured Carl impudently, "Venice called them bravi; here in America we brutally call them gun-men, but honestly, Kronberg, in all respect and confidence, you really haven't brains and originality enough for a clever professional murderer. Amateurish killing is a sickly sort of sport. And the danger of it! Take for instance that night when you fancied you were a motor bandit and waylaid me on the way to the farm. I was very drunk and driving madly and I nearly got you. A pretty to-do that would have been! To be killed by an amateur and you a paid professional! My! My! Kronberg, I blush for you. I really do!"
He rose smiling, though his eyes were dangerously brilliant.
"Just when," said he lazily, "did you steal the paper I found in the candlestick? It's gone--"
He had struck fire from the stone man at last. A hopeless, hunted look flamed up in Kronberg's eyes and died away.
"Ah!" guessed Carl keenly, "so you're in some muddle there, too, eh?" Kronberg stared sullenly at the dusty floor.
"A silence strike?" inquired Carl. "Well we'll see how you feel about that in the morning. As for the skylight, Kronberg, if you feel like skating down an icy roof to hell, try it."
Whistling softly, Carl backed to the door and disappeared. An instant later came the click of a key in the lock. He had taken the lamp with him.
