The detectives were not then in evening dress. They wore the business suits and woolen caps in which they had journeyed from New York the previous day in Nick’s powerful touring car. Each had in his pockets, moreover, a brace of revolvers and a disguise or two, taken from their suit cases that morning, without which frequently needed articles they never left home.

Danny Maloney, the detective’s chauffeur, then was asleep in the house, Nick having decided not to arouse him before he was definitely needed.

“I want one look at the grounds near that bulkhead door,” he observed, replying to Chick. “It will show whether Toulon put up any struggle with his three assailants, if there really were three.”

“You doubt that, also?” questioned Chick.

“I doubt most of what Toulon stated.”

“You took extraordinary care to hide your distrust,” replied Chick, smiling.

“Bet you!” said Nick tersely. “He was the best thread I could pick up, if not the only seemingly reliable one, and I made sure of keeping him in the dark.”

“But why did you suspect him so quickly?”

“Because he, or a counterpart of him, had been to Clayton’s room,” Nick explained. “I no sooner began to question him, Chick, than I felt sure I was right.”

“Why so?”
