Mr Cheyney has transported to England not only the American 'mobsters', but also their brilliantly witty and lightning repartee. With his obvious gift for characterisation we are presented with a story that surpasses the thrilling pace, convincing realism and entertainment value of such films as The Thin Man and The Big Sleep. This Man Is Dangerous is the story of organised gangsters operating the kidnapping or 'snatch' racket; the laying of a plot, worked out to the minutest detail, to 'snatch' the daughter of an American millionaire while she is in England; a plot that must not only account for the actual luring of the victim into the snare and the collecting of the ransom money, but must forbid interference from the English police and 'muscling-in' by rival gangs.
