"Ah!" he laughed with an air of forced gaiety. "That is amusing!"

"I'm very glad you think so, my dear sir," remarked the detective, glancing round to where the woman Petre had been placed in an armchair quite unconscious.

Phrida was clinging to my arm, but uttered no word. I felt her fingers trembling as she gripped me.

"I suppose you believe this native—eh?" asked the accused with sarcasm. "He tried to blackmail me in Peru, and because I refused to be bled he made a statement that I had killed my friend."

"Ah!" exclaimed the native. "Senos knows—he see with his own eyes. He see Luis and you with snake in a box. Luis could charm snakes by music. Senos watch you both that night!"

"Oh! tell what infernal lies you like," cried Cane in angry disgust.

"You, the 'Red' Englishman, are well known in Peru, and so is your friend—the woman there, who help you in all your bad schemes," said Senos, indicating the inanimate form of Mrs. Petre. "You introduced her to my master, but he no like her—he snub her—so you send her to Lima to wait for you—till you kill him, and get the paper—eh? I saw you steal paper—big blue paper with big seals—from master's despatch-box after snake bite him."

"Paper!" echoed Edwards. "What paper?"

"Perhaps I can explain something," Frémy interrupted in French. "I learnt some strange facts only three days ago which throw a great deal of light on this case."

"I don't want to listen to all these romances," laughed Cane defiantly. He was an astute and polished adventurer, one of the cleverest and most elusive in Europe, and he had all the adventurer's nonchalance and impudence. At this moment he was living in that fine house he had taken furnished for the summer and passing as Mr. Charles K. Munday, banker, of Chicago. Certainly he had so altered his personal appearance that at first I scarcely recognised him as the elegant, refined man whom I had so foolishly trusted as a friend.
