"The Doctor's Case" is a short story by American author Stephen King, originally published in The New Adventures of Sherlock Holmes, a 1987 centennial collection, and reprinted in his collection Nightmares & Dreamscapes. This story is King's foray into Sherlockiana, a non-canonical Sherlock Holmes story, using Arthur Conan Doyle's characters. Like his story "Crouch End", inspired by H. P. Lovecraft's Cthulhu Mythos, "The Doctor's Case" is an example of a pastiche.
