"Then why take the risk of a trial? Innocent men have been convicted, even when ably defended!"

"Yes, and guilty ones have escaped. But you ask why I do not leave New York. I answer, because I wish to remain here. Were I to run away from these charges, of course I should never be able to return."

"Then, Doctor, I advise you to surrender."

"I will adopt your advice. But not until the day after to-morrow. I have some affairs to settle first."

"But you risk being captured by the detectives."

"I think not," said the Doctor, with a smile.

"Should we wish to communicate with you, where may we be able to find you, Doctor?"

Doctor Medjora appeared not to have heard the question. He said:

"Oh! By the way, gentlemen, you need not either of you study up chemistry, as did Mr. Munson. You remember the case? I know enough chemistry for any experts that they may introduce, and will formulate the main lines of their cross-examination myself. Let me refer to a point that you made. Did I understand you that if we can show that Mabel died of diphtheria, our case is won?"

"Why, certainly, Doctor. If we can prove that, we show that she died a natural death."
