On this day in 1926, in an ironic parody of her mystery novels, Agatha Christy vanishes under mysterious circumstances. The event inspires a 1,500-person manhunt, massive media coverage, and even the hiring of a psychic detective by fellow novelist Sir Arthur Conan Doyle. She is found 10 days later, checked into a hotel under the surname of her husband’s lover, having no memory of how she got there.
