Set in the late 1920s-early 1930s, When the Gangs Came to London is rated as one of Edgar Wallaces best work by fans of his genre of crime fiction. Two rival gangs from Chicago coming to London and competing to blackmail rich men into paying up to prevent being killed. When a lull ensues, Captain Jiggs Allermain of the Chicago Detective Bureau suspects the rival gangs of forming an uneasy alliance. Suddenly a shot rings through the House of Commons, unleashing an outburst of terror even more bloody. Wallace wrote this one towards the end of his life, he may even have been in Hollywood when he wrote it which could explain the very old school Hollywood gangsters!
