"Well," insisted Bob, "I'd like to have that part of it explained to me. You don't suppose for a minute that Mr. Wernberg locked himself in, do you?"

"Mr. Wernberg wasn't the only man in the house, you know," said Bob.

"Who else was there?"

"Didn't Hugh and two of the detectives chase another man?"

"Yez mean the fake detective?" asked Sergeant Riley.

"I do."
