Jack O' Judgment

They picked up the young man called "Snow" Gregory from a Lambeth gutter, and he was dead before the policeman on point duty in Waterloo Road, who had heard the shots, came upon the scene.
He had been shot in his tracks on a night of snow and storm and none saw the murder.
When they got him to the mortuary and searched his clothes they found nothing except a little tin box of white powder which proved to be cocaine, and a playing card—the Jack of Clubs!
His associates had called him "Snow" Gregory because he was a doper, and cocaine is invariably referred to as "snow" by all its votaries. He was a gambler too, and he had been associated with Colonel Dan Boundary in certain of his business enterprises. That was all. The colonel knew nothing of the young man's antecedents except that he had been an Oxford man who had come down in the world. The colonel added a few particulars designed, as it might seem to the impartial observer, to prove that he, the colonel, had ever been an uplifting quantity.
