Copenhagen, 1932: a timid bank clerk walks into a branch office with a revolver, leaves two men dead, and insists “he told me I must,” pushing the Belgian Detective and his loyal companion into a chilling case of influence, sedatives, and staged “experiments” where a polished mind-lecturer hides behind props, philosophy, and respectable rooms; as a physician receives anonymous threats, prison visitor signatures repeat in the same careful hand, and a faint medicinal scent clings to a hatband like an invisible fingerprint, the investigation tightens around the question no one wants to face—how far can a weak will be driven, and who is truly guilty when a crime is planted piece by piece; inspired by historical crime of its era while remaining entirely fictional, The Man Who Dreamed Another Man’s Crime is an original Golden Age–style mystery about manipulation, responsibility, and the danger of “fashionable” ideas.
