greatly interested, of course, and had plenty to think of till I saw George again and learned the result of the latest investigations. Miss Challoner had been shot, not stabbed. No other deduction was possible from such facts as were now known, though the physicians had not yet handed in their report, or even intimated what that report would be. No assailant could have approached or left her, without attracting the notice of some one, if not all of the persons seated at a table in the same room.
