"It's Miss Vaughan—she's been half-suffocated. But how did you get in?"

"The gates were open," Hinman answered, "so I drove right through. Is Miss Vaughan in here?" and when Godfrey nodded, he opened the door and closed it softly behind him.

"Open!" repeated Godfrey, staring at me. "Open! Then that is the way Silva went!"

"Yes, yes," I agreed. "He had the key. It was he who let me out."

"And locked the gate after you?"

"Yes—I heard the key turn."

Without a word, Godfrey hurried down the stairs. At the foot we met Simmonds.

"We've searched the grounds," he said, "but haven't found anyone. I've left my men on guard. I 'phoned for some more men, and notified headquarters."

"He's not in the grounds," said Godfrey. "He went out by the gate," and he told of Hinman's discovery.

"I'll stretch a net over the whole Bronx," said Simmonds. "I don't see how a fellow dressed as he is can get away," and he hastened off to do some more telephoning.
