“Mr. Barnes is your next neighbor?”

“He is.”

“How does it come, then, that he did not see you until after seven?”

“The reason of that was, that in my haste I was careless, and in going down the stairs I tripped and fell, as a result of which I landed at the foot in a senseless condition.”

“What stairs were these?”

“Those at the front of the house.”

“There is a stair at the rear?”

“Yes, sir.”

“How did it happen that you did not first untie your fellow servants?”

“I cannot explain that, sir, even to myself. I merely knew that my master was murdered, and was anxious to get his friend here as soon as possible.”
