About this book
When the law cannot reach a criminal, who has the right to punish?
Jack O' Judgment by Edgar Wallace draws you into a shadowy criminal underworld, where the pull of justice meets the urge for vengeance. Crooks, detectives and ordinary citizens live close together. Dark corners and hidden meetings make this a world where people are not always what they seem.
Wallace brings a reporter's sense of pace to crime fiction. Streets and rooms feel concrete, while short chapters keep you moving toward the next clue or surprise. Beneath that forward rush lies an uneasy question: where does justice end and private punishment begin? The tension gives you more than a puzzle to follow.

A Playing Card Haunts a Powerful Man
Colonel Dan Boundary lives in a grand flat in Albemarle Place and wants for nothing. One morning a letter marked private holds only a soiled Knave of Clubs with a name along its edge. The words are Jack o' Judgment. The colonel tosses it away, but he cannot toss away the face it calls to mind.
That face belongs to Snow Gregory, a gambler who once worked for him. Gregory was shot dead in a Lambeth gutter with the same card on his body. A coroner's jury blamed persons unknown.
