"Are you sure?" I asked.

"Perfectly," he said. "In the evening, at about half-past nine."

"At half-past nine, on the tenth!" I exclaimed. "Why, she was at the theatre at that hour. I saw her."

"Impossible!" said the doctor. "You must have been mistaken; someone like her, perhaps."

"No, no, doctor," I firmly asserted; "I tell you she was in a box near the stage while I was acting Hamlet. I was as near to her as I am to you now; it is impossible that I could be mistaken."
