me by-and-by. I shouldn't be at all surprised if you imagined I induced
you to come in here to get you into a trap."

"You are perfectly correct," said Stratton; "and I may say, although
that was my belief, I was not in the least afraid of you, for I had you
covered all the time."

"Well," remarked Roland, carelessly, "I don't want to interfere with
your business at all, but I wish you wouldn't cover me quite so much;
that revolver of yours might go off."

"Do you mean to say," said Stratton, "that there is nothing but quinine
in those capsules?"

"I'll tell you in a moment," as he opened them one by one. "No, there is
nothing but quinine here. Thirty grains put up in five-grain capsules."

George Stratton's eyes began to open. Then he slowly rose, and looked
with horrified face at the doctor.

"My God!" he cried; "who got the thirty grains of morphia?"

"What do you mean?" asked the doctor.

"Mean? Why, don't you see it? It is a chemist's mistake. Thirty grains
of quinine have been sent you. Thirty grains of morphia have been sent
to somebody else. Was it to William Brenton?"

"By Jove!" said the doctor, "there's something in that. Say, let us go
to the drug store."
