"I should like you to tell me what my brother has been taking twice a day for the last month or so."

"Frankly, Miss Leicester, I don't know. We will speak of this when we get to my house,"

We walked on quickly without another word till we reached Dr. Haberden's. He asked me to sit down, and began pacing up and down the room, his face clouded over, as I could see, with no common fears.

"Well," he said at length, "this is all very strange; it is only natural that you should feel alarmed, and I must confess that my mind is far from easy. We will put aside, if you please, what you told me last night and this morning, but the fact remains that for the last few weeks Mr. Leicester has been impregnating his system with a drug which is completely unknown to me. I tell you, it is not what I ordered; and what that stuff in the bottle really is remains to be seen."

He undid the wrapper, and cautiously tilted a few grains of the white powder on to a piece of paper, and peered curiously at it.

"Yes," he said, "it is like the sulphate of quinine, as you say; it is flaky. But smell it."

He held the bottle to me, and I bent over it. It was a strange sickly smell, vaporous and overpowering, like some strong anæsthetic.

"I shall have it analyzed," said Haberden. "I have a friend who has devoted his whole life to chemistry as a science. Then we shall have something to go upon. No, no, say no more about that other matter; I cannot listen to that, and take my advice and think no more about it yourself."

That evening my brother did not go out as usual after dinner.

"I have had my fling," he said with a queer laugh; "and I must go back to my old ways. A little law will be quite a relaxation after so sharp a dose of pleasure," and he grinned to himself, and soon after went up to his room. His hand was still all bandaged.
