The Man Who Knew How

Originally Aired: August 10, 1944 In Suspense #104, “The Man Who Knew How,” a chance conversation on a train plunges the unassuming Mr. Pender into a nightmare of suspicion and obsession. When a stranger boasts of knowing the perfect, undetectable way to murder—by poisoning with a compound triggered by a hot bath—Pender brushes it off as a morbid joke. But as deaths-by-bath mount in his neighborhood, he becomes convinced he’s stumbled upon a real-life killer who’s quietly getting away with murder. Paranoia mounts, loyalties shift, and justice grows murky in this ingenious psychological thriller about trust, guilt, and the seductive appeal of the “perfect” crime.
