“What did the doctor have in his pockets?”

“Four five-pound notes, no change, and his watch was gone. There was nothing in his watch pocket except a watch crystal. His keys were gone, too, and only the ribbon of his watch was left lying on the floor.”

“What did the doctors say about his death?”

“Straight paralysis, they said. I had been away for three days. He was around the laboratory for one day after I left, and the day after that he must have died. They said death was instantaneous.”

“Did the doctor leave any family?”

“None.”

“What became of his papers?”

“Nobody knows. He had scarcely any friends. His property went to a niece in Germany, and she came over to hunt for papers, but she found none.”

“What became of the other assistant?”
