"Do you remember what you did with it, dear?"
Aunt Amy looked frightened.
"I—I don't know. I've a very good memory, Esther. But somehow I'm not quite sure."
"You will remember presently," said Callandar kindly. "We want to be quite sure that it was destroyed. You know, I explained to you, that Mary must take no more of that medicine. It is very dangerous…."
"What does it do?" unexpectedly.
"It is a kind of poison. It makes people very ill, so ill that in time they die."
"Mary likes it. She says it makes her nerves better and puts her to sleep."
"When did she say that?"
"When she asked me if I had any."
The doctor and the girl exchanged a quick look.
