"What is the exact nature of Miss Morton's injuries?" he asked.

"She has no injuries, at least in the sense I think you mean. She is suffering solely from the effects of shock."

"There is no evidence of any violence?"

"None whatever. But the effects of shock are often worse than those of actual physical violence. They have frequently been known to cause death."

"You do not, I hope, anticipate anything of the sort in this case."

"I cannot say." The doctor shook his head. "She must have been very weak. Her system is responding very slowly."
