"Yes, sir."
"How do you know?"
"I have had them tested."
"Did any blood come from the corpse?"
"No, sir; the skin of the neck was not broken."
"Where, then, in your opinion, did this blood come from?"
"From the murderer," answered Simmonds, quietly.

Goldberger, his face hawklike, stooped again to the suit-case, produced a third bundle, and, unrolling it, disclosed another robe, also of white silk. This, too, he handed to Simmonds.
