“A choice, certainly. Perhaps you are inclined not to testify. If so, very well. But before you make your decision I desire to inform you of one fact. You will remember that I said in the beginning that I brought you down here to tell you something.”

“Merely this. That Miss West has discovered that I am behind this affair.”

“What!” Doctor Sherman fell back a step, and his face filled with sudden terror. “Then—she knows everything?”

“She knows little, but she suspects much. For instance, since she knows that this is a plot, she is likely to suspect that every person in any way connected with the affair is guilty of conspiracy.”

“Even—even me?”

“Even you.”

“Then—you think?”
