The Adventure of the Three Garridebs (1924), one of the 56 Sherlock Holmes short stories written by British author Sir Arthur Conan Doyle, is one of 12 stories in the cycle collected as The Case-Book of Sherlock Holmes.

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...
