“How did Mr. Rochester come to make that assertion and where?”

“Immediately after Turnbull's death,” replied Stone. “Mr. Rochester, who shared his apartment, defended him in court. Mr. Rochester was aware that Turnbull suffered from the disease, and Mr. Clymer, who was present, also knew it.”

“And what is your opinion, doctor?” questioned Penfield.

Stone hesitated. “There was a distinct odor of amyl nitrite noticeable when I went to Turnbull's aid, and I concluded then that he had some heart trouble and had inhaled the drug to ward off an attack. It bears out Mr. Rochester's theory of death from angina pectoris.”

“I see. Thank you, doctor. Please wait with the other witnesses; we may call you again,” and with a sigh the busy physician resigned himself to spending another hour in the room reserved for the witnesses.

The next to take the witness stand was Deputy Marshal Grant. His testimony was short and concise,—and his description of the scene in the police court preceding Turnbull's death was listened to with deep attention by every one.

“Did the prisoner show any symptoms of illness before his heart attack?” asked Penfield.

“Not exactly illness,” replied Grant slowly. “I noticed he didn't move very quickly; sort of shambled, as if he was weak in his legs. I've seen 'drunk and disorderlies' act just that way, and paid no particular attention to him. He did ask for a drink of water just after he returned to the cage.”

“Did you give it to him?”

“No, an attendant gave the glass to Mr. Rochester who handed it to Mr. Turnbull.”
