"Well, sir?" he said, looking up with an offended air. "Is there anything else I can explain? or will you have the kindness to return my property to me now?"

"There is one thing, about which I should like to ask a question," I said.

"Ask on," he replied; and I wondered whether there was not a little too much of bravado in the tone of sufferance he assumed.

"Why do you carry"--I went on, raising my eyes to his, and pausing on the word--"that little medicament--you know what I mean--in your waistcoat pocket?"

He flinched. "I don't quite--quite understand," he began to stammer. Then he changed his tone and went on rapidly, "No! I will be frank with you, Mr. Mr.----"

"George," I said.

"Ah, indeed?" a trifle surprised, "Mr. George! Well, it is something Bristowe gave me this morning to administer to my father--without his knowledge, if possible--should he grow excited. I did not think that you had seen it."

Nor had I. I had only inferred its presence. But having inferred rightly, I was inclined to trust my inference farther. Moreover, while he gave this explanation his breath came and went so quickly that my former suspicions returned. I was ready for him when he said--

"Now I will trouble you, if you please, for those papers?"

"I cannot give them to you," I replied, point blank.
