"The Adventure of the Three Garridebs" is one of the 56 Sherlock Holmes short stories written by British author Sir Arthur Conan Doyle. One of the 12 stories in the cycle collected as The Case-Book of Sherlock Holmes (1927), it was first published in Collier's in the United States on 25 October 1924, and in The Strand Magazine in the United Kingdom in January 1925. According to Dr. Watson's opening narration, this story is set at "the latter end of June, 1902 ... the same month that Holmes refused a knighthood for services which may perhaps some day be described." This is a parallel to the knighthood of Arthur Conan Doyle around the same time. Plot Holmes receives a letter from a Nathan Garrideb of 136 Little Ryder Street, asking for help in a most peculiar quest. He is looking for another man with his unusual surname, for it will mean a $5 million inheritance for him. He has been approached by another man, John Garrideb of Kansas, who says that he needs to find others with the same last name. The American Garrideb comes to see Holmes and Watson at 221B Baker Street, and is apparently not very pleased that Nathan Garrideb has involved a detective. Garrideb, who claims to be a lawyer, spins a ridiculous story about Alexander Hamilton Garrideb, a millionaire land tycoon he met in Kansas. Hamilton Garrideb bequeathed his $15 million estate to John Garrideb on the provision that he find two more Garridebs to share it with equally. He came to England to seek out people with the name, having failed in his own country. So far, he has found only Nathan. During the interview, Holmes secretly deduces that Garrideb has been in London for a long time, not newly arrived as he claims. When Holmes invents a fictitious Kansas politician, Garrideb says he once knew him. Holmes does not reveal that he knows Garrideb is lying, and instead arranges a private visit with Nathan Garrideb. Upon arrival at Little Ryder Street, Holmes observes Nathan Garrideb's nameplate outside the house. It has obviously been there for years; so Holmes concludes that Garrideb is at least his true surname. It turns out that Nathan Garrideb is an elderly eccentric who collects everything from ancient coins to old bones. Garrideb's rooms look like a small museum, but he has nothing of financial value in his collection.
