"The suggestion came to me a long time ago—more than a year," I responded. "Since then it has been constantly in my mind, and at last I decided to act upon it."

"That does not answer my question, Mr. Derrington."

"The idea first came to me through an old friend; one whom I used to know here, in this country; one who afforded me very great assistance when I was here three years ago on a secret mission for my government."

"What is his name?"

"I have forgotten it."

"You are troubled with a poor memory, sir."

"Yes; concerning the names of friends who have assisted me when they have been compelled to place their own interests in jeopardy in order to do so."

"Do you know Alexis Saberevski?"

"I do."

"Can you tell me where he is now?"
