He walked quietly around the corner past the power equipment. No Lydman. The next step was the laboratory. He looked at his watch, then leaned against the wire mesh partition for a good ten minutes. Let Parrish cover the ground, he decided.

In the end, with no sign of Parrish or Lydman, he opened the door and stepped into the dark laboratory. He made his way cautiously ahead, thinking that Lydman was probably in his office. Feeling his path with slow steps, and carefully avoiding the possibility of tipping over any of the stacks of cartons, he had progressed to the center of the large chamber when the lights went on.

Westervelt felt as if he had jumped a foot, and the blood pounded through his veins.

Gaping around with open mouth, he finally met the eye of Pete Parrish, who stood half inside the doorway to the corridor, his hand still raised to the light switch.

"Well," said Parrish, "where was he?"

Westervelt closed his eyes and groaned.

"You're kidding," he said. "Please say you're kidding! It's too late in the day to fool around, Pete."

Parrish looked alarmed. He strode forward, letting the door close behind him. Westervelt, finding himself shivering in a draft, went to meet him.

"I'm not kidding at all," said Parrish. "Did you look everywhere? Are you sure?"
