In "The 25th Hour!", Arthur Mellon’s experiment with a revolutionary cigarette filter takes a strange turn when he begins experiencing vivid premonitions—first of an assassination, then of a sudden stock market surge. As reality blurs and his predictions come true, Arthur finds himself caught in a chain of events he can’t explain, all triggered by a single, seemingly ordinary smoke. With art by Ogden Whitney on both interior and cover, this 1977 Alan Class issue delivers a mind-bending mystery wrapped in a pocket-sized thriller.
