“It appears that he is at work in Russia again. Somewhere in the centre,” Miss Haldin said, with animation. “But please don’t mention that to any one—don’t let it slip from you, because if it got into the papers it would be dangerous for him.”

“You are anxious, of course, to meet that friend of your brother?” I asked.

Miss Haldin put the letter into her pocket. Her eyes looked beyond my shoulder at the door of her mother’s room.

“Not here,” she murmured. “Not for the first time, at least.”

After a moment of silence I said good-bye, but Miss Haldin followed me into the ante-room, closing the door behind us carefully.

“I suppose you guess where I mean to go tomorrow?”

“You have made up your mind to call on Madame de S—.”

“Yes. I am going to the Chateau Borel. I must.”

“What do you expect to hear there?” I asked, in a low voice.

I wondered if she were not deluding herself with some impossible hope. It was not that, however.
