The car drove for, maybe, twenty minutes. Stone tried to keep track of the time and the turns, but he couldn’t see his watch, and, not knowing the street plan well enough, he couldn’t figure out where they were going. They seemed to drive around three or four traffic circles, and shortly after the last one, they made a right turn and stopped. The two men in the rear seat hustled Stone through an open door in a narrow back street and into a darkened hallway. They marched Stone along, making a couple of turns, then he was propelled forward into a small room, bouncing off the rear wall, and the door was slammed behind him.

“You have one minute to strip off all your clothes, or we’ll do it for you,” the deep voice said.

Stone thought about this for half a minute, then he got out of his clothes and laid them neatly on a bench along one wall. His eyes had become accustomed to the gloom, and he could see that he was in a windowless room with a steel door. There was a bucket in a corner and the bench, no other furniture. A moment later, a small door in the larger one opened, then closed, then the two men came into the cell, took away his clothes, and slammed the door behind them.

Stone thought about it. These people did not seem like the police. Surely the London police had procedures about arrest and detention, just as the New York department did, and what he was experiencing did not seem to conform to any set of procedures in any civilized country. This was more like something out of a World War II film about the Gestapo, or a spy novel.

Perhaps three minutes passed, then the cell door opened again, and someone threw his clothes at him.

“Get dressed,” the deep voice said. “You have one minute.”

Stone was tying his necktie when the door opened again and he was half escorted, half dragged down another series of hallways, then pushed into a brightly lit room, the door slamming behind him.

Blinking rapidly, he discovered that all the room was not brightly lit, just the part containing a wooden stool. The other side of the room, some twelve or fifteen feet away, contained a table behind which sat three men. They were in deep shadows and he could see only their forms, not their faces. It seemed to be arranged as some sort of Stalinist tribunal.

“Sit down, please, Mr. Barrington,” a smooth male voice said.

Stone went and sat down on the stool. There was something odd about the man’s voice, but he couldn’t figure it out.

The smooth voice spoke again, and Stone figured it was coming from the man in the middle, who was bald, with a bullet-shaped head. “Tell us, please, if you have ever heard the following names, in any context: Robert Graves?”

“What?”
