“Did you call just then?” demanded the watchman.
“I’ll say I did,” replied Bob. “Someone was trying the door here and when I tried to open it, the door stuck. Then I let out a whoop. Didn’t you see anyone?”
“No one came my way,” said the guard quickly, but his eyes did not meet Bob’s squarely. “We’d better look along this end of the corridor. If someone was here, he might have slipped into one of the other offices.”
Bob shook his head.
“No, he wouldn’t have done that. Besides, I distinctly remember hearing him running down toward the elevators.”
“Well, I wasn’t asleep and no one came my way,” insisted the guard. “Maybe you were dreaming a little. You look kind of tired.”
“I am tired, but this was no dream,” insisted Bob. Then he remembered the door. What had made it stick? It hadn’t been locked.
“Give me your flashlight,” said Bob and the guard handed over a shiny, metal tube.
Bob turned the beam of light on the floor, and searched closely.
“What are you looking for?” asked the guard.
