"You have destroyed every possible theory," said the captain, deeply interested, "and have suggested nothing new."
"Unfortunately, I cannot; but the truth may be very simple, after all. The old surgeon is so peculiar that I am prepared to discover something remarkable."
"Have you suspicions?"
"I have."
"Of what?"
"A crime. The woman suspects it."
"And betrays it?"
"Certainly, because it is so horrible that her humanity revolts; so terrible that her whole nature demands of her that she hand over the criminal to the law; so frightful that she is in mortal terror; so awful that it has shaken her mind."
"What do you propose to do?" asked the captain.
"Secure evidence. I may need help."
