Young Blood is a novel by E. W. Hornung. Hornung was an English author and poet known for his crime stories. Excerpt: "The cab-door was flung open and out sprang an utter stranger to Harry Ringrose. This was a middle-aged man of the medium height, wearing a somewhat shabby tall hat and a frock-coat which shone unduly in the strong sunlight. He had a fresh complexion, a reddish moustache streaked with grey, a sharp-pointed nose, and a very deep chin which needed shaving; but what struck Harry first and last were the keen, decisive eyes, twinkling behind glasses with gold rims, which went straight to the broken window and surveyed it critically before their owner had set foot on the steps."
