"But, good God! I have told you the truth!" cried Chaleck.

"And you heard nothing, although you were only a few yards away?"

"Nothing at all. I sat up working very late last night. When I went to bed, nothing had happened in the least suspicious. Oh, by the way, toward morning I did hear a slight noise. I rose and went over the house, even coming into this room. I found everything in order."

"That's a likely tale!"

"Here's a proof of what I say! When I returned to this study I used that candle and sealing wax to seal my letter, which, as you can see, is still here. Your ring at the bell awoke me not more than twenty minutes later, just as I was getting to sleep again."

"Lies!" cried Michel, turning to Juve. "Shall I arrest him?"

"The doctor is telling the truth," replied Juve, half regretfully.

Chaleck seemed very much relieved.

"Oh, you'll help me, won't you? Get me out of this abominable affair!"

As a matter of fact, Chaleck had accounted for his time with exact truthfulness.
