Jack O’ Judgment by Edgar Wallace

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!
