“What is it? Some new danger? Tell me!”

“Oh! nothing serious. Only....”

“Only what?” she asked.

“Well, he is on our track.”

“Who? Herlock Sholmes?”

“Yes; it was he who dragged Ganimard into that affair at the Hungarian restaurant. It was he who instructed the two policemen to watch the house in the rue Chalgrin. I have proof of it. Ganimard searched the house this morning and Sholmes was with him. Besides——”

“Besides? What?”

“Well, there is another thing. One of our men is missing.”

“Who?”

“Jeanniot.”
