"Strike a light and hold it as I direct—then draw it away slowly."
He lifted the partly closed eyelid from one of the eyes of the unconscious man and nodded to Eaton: "Hold the light in front of the pupil."
Eaton obeyed, drawing the light slowly away as Sinclair had directed, and the surgeon dropped the eyelid and exposed the other pupil.
"What's that for?" Avery now asked.
"I was trying to determine the seriousness of the injury to the brain. I was looking to see whether light could cause the pupil to contract."
"Could it?" Connery asked.
"No; there was no reaction."
Avery started to speak, checked himself—and then he said: "There could be no reaction, I believe, Dr. Sinclair."
"What do you mean?"
"His optic nerve is destroyed."
