“The whole block,” Stone replied. “It’s the largest store in the world.”

“Jesus,” Dino said, “I’ll need a map.”

“Just wander, and ask somebody if you get lost.”

“Okay, pal; when will I see you?”

“I’ll come back to the house after lunch; if anybody calls and asks for me, except Sarah, you don’t know me.”

“I might be better off,” Dino said.

“Maybe, but you wouldn’t have nearly as much fun.”

Dino closed the door and walked into Harrod’s.

Stone drove on out Knightsbridge, which became the Cromwell Road, and soon he was on a four-lane highway, and soon after that, on the M4 motorway. Traffic was heavy, but he made good time. He got off the motorway at the prescribed exit and took the opportunity to check the traffic behind him. No one exited after him that he could see, and he felt tail-free, except for Mason’s van, which was nowhere to be seen.

He followed the signs to the village and the restaurant and parked the car. The Thames was before him, broad and slow-moving, with pretty houses on the other side. He went into the restaurant; it was precisely one o’clock. Lance was not there yet, and the maître d’ seated him outside on the terrace, under an elm tree. He ordered a kir royale and sipped it. Lance, he figured, was driving around the village to see if either he or Stone had a tail. Another fifteen minutes passed before he entered the restaurant.

Stone shook his hand. “A very elegant place,” he said.

“Wait until you taste the food.”

They had only desultory conversation until the food arrived, then Lance took a look around to be sure they were not being overheard. “I’m going to have to pat you down,” he said to Stone.

Stone laughed. “Don’t worry, I haven’t worn a wire in years, not since I was a cop.”

Lance got up, walked behind Stone and, on the pretense of pointing at something on the river, ran his hands expertly over Stone’s body, down to the crotch.

“Don’t have too much fun there,” Stone said.

“What’s this?” Lance asked, patting Stone’s jacket pocket.

Stone removed the pen and handed it to him.

Lance inspected it closely and unscrewed the cap.

Don’t try to unscrew the other end, Stone thought.

Lance didn’t; he returned the pen, and Stone put it back into his pocket.

“Now,” Lance said.

Stone leaned forward, as if to listen closely, putting his left hand on the table.

“I’m going to tell you everything I think you need to know.”

“If it’s everything I think I need to know, we’ll be fine.”
