“Do you know that man?” she asked suddenly.

Pete stiffened and looked sharply at her.

“What man?”

“The one you keep looking at. The one in the black suit. He’s been following us all the morning.”

“Has he?” Pete tried to keep his voice steady. “I — I think I’ve seen him somewhere before.”

By now they had reached the pay-box outside the maze, and Pete moved forward to buy the tickets. It seemed to be the only side-show where there was no queue, and the blonde, middle-aged woman seemed glad to sell him the tickets.

“Keep to your left as you go in,” she said as she gave him the change. “If you get lost ring the bell. You’ll find plenty of bell-pushes as you go through the maze. Someone will come and find you.”

Pete thanked her and joined Frances who was waiting at the entrance. He followed her down a long passage and at the last moment he looked back anxiously over his shoulder. He could see no sign of Moe.

“What do we do?” Frances asked as she walked just ahead of him. “It’s awfully stuffy in here, isn’t it?”

“You won’t find it stuffy once we get into the maze,” Pete assured her. “It’s in the open air.”
