"The Adventure of the Three Garridebs" is one of the 56 Sherlock Holmes short stories written by British author Sir Arthur Conan Doyle.

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."

Holmes receives a letter from a man named Nathan Garrideb of 136 Little Ryder Street,[2] in which the writer asks for help in finding someone else who shares his unusual surname.

In London, he had killed Rodger Prescott, a Chicago forger whose description matches the former occupant of Nathan Garrideb's room.

Holmes is distraught over Watson's injury, and strikes Winter on the head with the butt of a gun hard enough to draw blood.

Nathan Garrideb ends up in a nursing home, so great is his disappointment, but many CID men are pleased that Prescott's equipment has at last been found.

As noted by Wilma Morgan: "The Three Garridebs" takes up many plot elements used in the much earlier story 'The Red-Headed League.'

Both stories feature a rather naive, sedentary, middle aged bachelor who happens to sit on a location of great interest to cunning criminals.

"[7]The story was adapted by Edith Meiser as an episode of the American radio series The Adventures of Sherlock Holmes.

[13] The then-newly formed NBC sought permission from Lady Conan Doyle to produce The Three Garridebs for American television in 1937.

Jeremy Brett was taken ill during the production of the Granada Television adaptation of this story (which was also a conflation with "The Adventure of the Mazarin Stone" and transmitted under the latter title) and so Holmes's role in the plot was taken by Mycroft Holmes with Charles Gray called in at short notice to reprise his role as Sherlock's older brother.
