"Who opened the door, then?—What's that in your hand?"

"The chloroform, Sir, you just handed me."

"Just handed you?"

"Yes, Sir;—you gave it back to me not a quarter of a minute ago."

"Have I been asleep, Martin?"

"I should judge not, Sir. You didn't take more than two sniffs at the bottle. I just had time to go to the door when you spoke to me."

"Martin,—is the window close?"

"Perfectly close, Sir."

"You may go."
