And he recalled the affair of the blue diamond and his first interview with Clotilde Destange. Had not the blonde Lady met his question with the same unruffled serenity, and was he not once more face to face with one of those creatures who, under the protection and influence of Arsène Lupin, maintain the utmost coolness in the face of a terrible danger?

“Sholmes ... Sholmes....”

It was Wilson who called him. Sholmes approached the bed, and, leaning over, said:

“What’s the matter, Wilson? Does your wound pain you?”

Wilson’s lips moved, but he could not speak. At last, with a great effort, he stammered:

“No ... Sholmes ... it is not she ... that is impossible——”

“Come, Wilson, what do you know about it? I tell you that it is she! It is only when I meet one of Lupin’s creatures, prepared and instructed by him, that I lose my head and make a fool of myself.... I bet you that within an hour Lupin will know all about our interview. Within an hour? What am I saying?... Why, he may know already. The visit to the pharmacy ... urgent message. All nonsense!... She has gone to telephone to Lupin.”

Sholmes left the house hurriedly, went down the avenue de Messine, and was just in time to see Mademoiselle enter a pharmacy. Ten minutes later she emerged from the shop carrying some small packages and a bottle wrapped in white paper. But she had not proceeded far, when she was accosted by a man who, with hat in hand and an obsequious air, appeared to be asking for charity. She stopped, gave him something, and proceeded on her way.

“She spoke to him,” said the Englishman to himself.

If not a certainty, it was at least an intuition, and quite sufficient to cause him to change his tactics. Leaving the girl to pursue her own course, he followed the suspected mendicant, who walked slowly to the avenue des Ternes and lingered for a long time around the house in which Bresson had lived, sometimes raising his eyes to the windows of the second floor and watching the people who entered the house.
