A Graveyard for Lunatics oleh Ray Bradbury

Halloween Night, 1954. A young, film-obsessed scriptwriter has just been hired at one of the great studios. An anonymous investigation leads from the giant Maximus Films backlot to an eerie graveyard separated from the studio by a single wall. There he makes a terrifying discovery that thrusts him into a maelstrom of intrigue and mystery—and into the dizzy exhilaration of the movie industry at the height of its glittering power.
