"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.

Plot summary Dr. Watson narrates a heretofore unreleased case in which he and Holmes are called by Inspector Lestrade on an unexpectedly rainy day to investigate the murder of the sadistic Lord Hull. Each member of Hull's family - his wife and three sons - has reason to murder him; his wife and bowlegged son suffered from constant abuse, while another son was doomed to never receive more than a pittance, due to his placement in the family line. Furthermore, Hull's family endured his treatment in the hopes that he would leave them with his considerable wealth; however, they had recently learned that Hull had rewritten his will so that none of them received a thing.

When he goes to check the table, he discovers an illusion and demonstrates that the table has been rigged. The bookshelf's lowest shelf is, in fact, a photorealistic painting. The murderer, Hull's artist son Jory, had perfectly rendered the bottom shelf, then pasted the results against the back table-legs. When his father announced the new will, Jory made into the study, crouched behind the table, and rushed out to stab his father at the right moment. A cursory glance would not betray the illusion on a dark day, but on a sunny one, the lack of shadows being cast by the table-legs would have been noticeable. To help make the illusion perfect, Jory had prepared shadows out of black felt, and laid them down at roughly the place where shadows should be. Unfortunately, he was
