"Of course not," I said. "He overlooked the fact that Terrec tried to shoot his father last night, and that I took away his gun. All that counts for nothing when he finds my handkerchief at the murdered man's door."

"Come into the café," said Durand, much disturbed, "we can talk it over, there. Of course, Monsieur Darrel, I have never had the faintest idea that you were the murderer!"

The four gendarmes and I walked across the road to the Groix Inn and entered the café. It was crowded with Bretons, smoking, drinking, and jabbering in half a dozen dialects, all equally unsatisfactory to a civilized ear; and I pushed through the crowd to where little Max Fortin, the chemist of Quimperlé, stood smoking a vile cigar.

"This is a bad business," he said, shaking hands and offering me the mate to his cigar, which I politely declined.

"Now, Monsieur Fortin," I said, "it appears that the Purple Emperor found my handkerchief near the murdered man's door this morning, and so he concludes"—here I glared at the Purple Emperor—"that I am the assassin. I will now ask him a question," and turning on him suddenly, I shouted, "What were you doing at the Red Admiral's door?"

The Purple Emperor started and turned pale, and I pointed at him triumphantly.

"See what a sudden question will do. Look how embarrassed he is, and yet I do not charge him with murder; and I tell you, gentlemen, that man there knows as well as I do who was the murderer of the Red Admiral!"

"I don't!" bawled the Purple Emperor.

"You do," I said. "It was Yves Terrec."

"I don't believe it," he said obstinately, dropping his voice.
