I remembered that Blenkiron, who didn’t like his race, had once described him to me as “the whitest Jew since the Apostle Paul.”

In the library I found a tall man standing by the window looking out at our view. He turned as I entered, and I saw a thin face with a neatly trimmed grey beard, and the most worried eyes I have ever seen in a human countenance. Everything about him was spruce and dapper—his beautifully-cut grey suit, his black tie and pink pearl pin, his blue-and-white linen, his exquisitely polished shoes. But the eyes were so wild and anxious that he looked dishevelled.

“General,” he said, and took a step towards me.

We shook hands and I made him sit down.

“I have dropped the ‘General,” if you don’t mind,“ I said. ”What I want to know is, have you had breakfast?“

He shook his head. “I had a cup of coffee on the road. I do not eat in the morning.”

“Where have you come from, sir?” I asked.

“From London.”

Well, London is seventy-six miles from us, so he must have started early. I looked curiously at him, and he got out of his chair and began to stride about.

“Sir Richard,” he said, in a low pleasant voice which I could imagine convincing any man he tried it on, “you are a soldier and a man of the world and will pardon my unconventionality. My business is too urgent to waste time on apologies. I have heard of you from common friends as a man of exceptional resource and courage. I have been told in confidence something of your record. I have come to implore your help in a desperate emergency.”

I passed him a box of cigars, and he took one and lit it carefully. I could see his long slim fingers trembling as he held the match.

“You may have heard of me,” he went on. “I am a very rich man, and my wealth has given me power, so that Governments honour me with their confidence. I am concerned in various important affairs, and it would be false modesty to deny that my word is weightier than that of many Prime Ministers. I am labouring, Sir Richard, to secure peace in the world, and consequently I have enemies, all those who would perpetuate anarchy and war. My life has been more than once attempted, but that is nothing. I am well guarded. I am not, I think, more of a coward than other men, and I am prepared to take my chance. But now I have been attacked by a subtler weapon, and I confess I have no defence. I had a son, who died ten years ago at college. My only other child is my daughter, Adela, a girl of nineteen. She came to Europe just before Christmas, for she was to be married in Paris in April. A fortnight ago she was hunting with friends in Northamptonshire—the place is called Rushford Court. On the morning of the 8th of March she went for a walk to Rushford village to send a telegram, and was last seen passing through the lodge gates at twenty-minutes past eleven. She has not been seen since.”

“Good God!” I exclaimed, and rose from my chair. Mr. Victor was looking out of the window, so I walked to the other end of the room and fiddled with the books on a shelf. There was silence for a second or two, till I broke it.

“Do you suppose it is loss of memory?” I asked.

“No,” he said. “It is not loss of memory.
