"I did not, Monsieur."

Waberski smiled and twisted his moustache.

"Of course! Of course! We could not expect Mademoiselle to admit it. One fights for one's skin, eh?"

"But, after all," Hanaud interrupted, with enough savagery in his voice to check all Waberski's complacency, "let us not forget that on the 7th of May, Madame Harlowe had been dead for ten days. Why should Mademoiselle still be going to the shop of Jean Cladel?"

"To pay," said Waberski. "Oh, no doubt Jean Cladel's wares are expensive and have to be paid for more than once, Monsieur."

"By wares you mean poison," said Hanaud. "Let us be explicit."

"Yes."

"Poison which was used to murder Madame Harlowe."

"I say so," Waberski declared, folding his arms across his breast.

"Very well," said Hanaud. He took from his green file a second paper written over in a fine hand and emphasised by an official stamp. "Then what will you say, Monsieur, if I tell you that the body of Madame Harlowe has been exhumed?" Hanaud continued, and Waberski's face lost what little colour it had. He stared at Hanaud, his jaw working up and down nervously, and he did not say a word.
