"You are absolutely sure that you have no suspicion of the murderer's identity?" Cleek asked with a sharpness unusual to him. "No reason to doubt any living soul?"
For just the merest fraction of a second young Clavering appeared to hesitate.
"No," he said curtly. "No, I have not. I know no more about it than a child. Mellish told me about the murder, and it was only natural that I should come up here to make inquiries."
"But, yes, monsieur, of course," agreed Cleek softly. "There is, then, no more to be said save good-bye. I fear me I shall not have the pleasure of meeting you again, as I return to Paris to-morrow. The case is one of the most mysterious, and I leave it to your English detective, Mr. George Headland. So it is adieu, monsieur, and not au revoir."
He held out his hand to the young man, who grasped it in his own trembling one, and then, with a sharp "good-night," Geoff Clavering turned and strode back in the direction whence he had come.

"Make of it, Mr. Narkom? Well, for one thing, I make of it that that young man lied like a pickpocket and deliberately attempted to throw dust in our eyes. He not only does suspect some one—and with good grounds, too—but he has been here before and in that house to-night. In other words, his was the foot that crushed that golden capsule. The scent of the Huile Violette was upon the drawing paper, the measure, the muffler, the cap—every blessed thing he trod on in his scuffle with Dollops!"
"Good God! Oh, his poor father! Surely, surely, Cleek, you do not believe——"
