“Not now,” Joan said to him.

“Free sample of breakfast cereal,” the peddler said. “No cost. Just take a box, miss. You mister. Take one.” He extended the tray of small, gaily colored cartons toward Ray.

Strange, Ray thought. I’m not picking up anything from this man’s mind. He stared at the peddler, saw—or thought he saw—a peculiar insubstantiality to the man. A diffused quality.

Ray took one of the samples of breakfast cereal.

“Merry Meal, it’s called,” the peddler said. “A new product they’re introducing to the public. There’s a coupon inside. Entitles you to—”

“Okay,” Ray said, sticking the box in his pocket. He took hold of Joan and led her along the line of cabs. He chose one at random and opened the rear door. “Get in,” he said urgently to her.

“I took a sample of Merry Meal, too,” she said with a wan smile as he seated himself beside her. The cab started up, left the line and pulled past the entrance of the airfield terminal. “Ray, there was something strange about that salesman. It was as if he wasn’t actually there, as if he was nothing more than—a picture.”

As the cab drove down the auto ramp, away from the terminal, another cab left the line and followed after them. Twisting, Ray saw riding in the back of it two well-fed men in dark business suits. FBI men, he said to himself.

Joan said, “Didn’t that cereal salesman remind you of anyone?”

“Who?”

“A little of Wilbur Mercer. But I haven’t seen him enough to—” Ray grabbed the cereal box from her hand, tore the cardboard top from it. Poking up from the dry cereal he saw the corner of the coupon the peddler had spoken about; he lifted out the coupon, held it up and studied it. The coupon said in large clear printing:

HOW TO ASSEMBLE AN EMPATHY BOX FROM ORDINARY HOUSEHOLD OBJECTS

“It was them,” he said to Joan.

He put the coupon carefully away in his pocket, then he changed his mind.
