Fictional clowns come with a body count. Edgar Allan Poe’s Hop-Frog (1849) was a dwarf forced to be a jester who burned eight courtiers to death. Pagliacci features opera’s most famous clown, a sad sack who stabs his cheating wife to death onstage. In the early 1980s, clown panics erupted in Boston, Omaha, and Pittsburgh when rumors circulated that clowns were luring children into white vans. Clowns are part of the holy trinity of horror paperback iconography, along with skeletons and dolls, yet few books deliver death jesters.
