A strange thing had happened at the old fort during the still watches of the night. Even now, at nine in the morning, no one seemed to be in possession of the exact circumstances. The officer of the day was engaged in an investigation, and all that appeared to be generally known was the bald statement that the sentry on "Number Five" had fired at somebody or other about half after three; that he had fired by order of the officer of the day, who was on his post at the time; and that now he flatly refused to talk about the matter.
