Thinner

Thinner is a horror novel by American author Stephen King, published in 1984 by NAL under King's pseudonym Richard Bachman. The story centers on morbidly obese lawyer Billy Halleck, who, driving carelessly, kills an old Romani woman while she is crossing the street. He escapes legal punishment due to his connections, but the woman's 106-year-old father then curses Halleck to physically waste away, and the lawyer must find a way to undo the curse. King, who was overweight at the time of the novel's writing, created the novel’s outline following an annual medical examination.
