“That man gives me the creeps,” Louise remarked. “Did you believe what he said about the door sticking?”

“I did not,” Penny returned with emphasis. “I think he locked us in on purpose, probably because he was expecting visitors and didn’t want us to see too much.”

“As it turned out we didn’t learn a thing.”

“We have no proof of anything,” Penny admitted slowly. “Nevertheless, we’re pretty sure Mrs. Deline visited the tower.”

“George Emory too.”

“That part is pure guess,” Penny said, “so we don’t dare consider it too seriously. Did you ever see Mrs. Deline with George Emory?”

“Why, no. But then, we’ve not been at the hotel long.”

“Let’s find Jerry or Dad,” Penny said abruptly. “We ought to report to them.”

Returning to the hotel, the girls looked in vain for Mr. Parker. The publisher was not in his room nor anywhere in the lobby. Jerry apparently had not returned from Intercept Headquarters.

“There’s Mrs. Deline,” Louise whispered, jerking her head toward a high-backed chair not far from the elevator.
