In the Murderer's Brain

In the Murderer's Brain collects Ray Cummings' most ingenious Scientific Club cases, where crimes are unraveled not by chance but by carefully staged experiments. Doctor Adams, Dr. Gregg, Detective Marberry and their circle of specialists treat criminal minds like laboratories: they reconstruct scenes with props and photographs, probe memory with deceptive readings and object arrays, analyze typewriter idiosyncrasies, read clues etched into ashes, and even stage controlled séances and pharmacological tests to separate truth from bluff. The club's methods are theatrical and precise-a faux crime scene here, a hypnotic suggestion there-yet always designed to exploit one constant: guilt leaves traces the conscious mind cannot hide. These tales range from heartbreaking mistakes of youth and fatal jealousies to cunning blackmail and calculating murder. In one case, a guilty memory betrays itself when a suspect confuses details after a planted narrative; in another, a burned scrap of paper reveals the name the arsonist thought destroyed; elsewhere, an apparently accidental drowning is solved by careful physics and weight displacement. Beyond the puzzles lie humane meditations on fear, remorse, and how ordinary people fail under extraordinary temptation. Witty, suspenseful, and rigorously plotted, In the Murderer's Brain is classic detective fiction for readers who love forensic cleverness and moral complexity.
