about three o’clock
I picked it up cheap from Harding Brothers , two doors from the High Street Station . A great deal of my journalistic work is done at night , and I often write until the early morning . So it was to-day . I was sitting in my den , which is at the back of the top of the house , about three o'clock , when I was convinced that I heard some sounds downstairs . I listened , but they were not repeated , and I concluded that they came from outside . Then suddenly , about five minutes later , there came a most horrible yell -- the most dreadful sound , Mr. Holmes , that ever I heard . It will ring in my ears as long as I live .
