three o'clock in the morning
Then I went to bed . The men were still in the billiard-room when I finally dozed off , and the last thing I remember was the howl of a dog in front of the house . It wailed a crescendo of woe that trailed off hopefully , only to break out afresh from a new point of the compass . At three o'clock in the morning I was roused by a revolver shot . The sound seemed to come from just outside my door . For a moment I could not move . Then -- I heard Gertrude stirring in her room , and the next moment she had thrown open the connecting door .
