In 1913 the Greek novel Sherlock Holmes saving Mr. Venizelos (Ο Σέρλοκ Χολμς σώζων τον κ. Βενιζέλον) was serialized in the magazine Hellas. Written by an anonymous author, it describes Holmes' attempts to save Eleftherios Venizelos from a Bulgarian organization's assassination plot during the London Conference of 1912–13. It is considered the first detective novel of the Greek literature. In January 1928, the short story "My Dear Holmes" was published in Punch, or the London Charivari. The sub-title of the story was: "His positively last appearance on earth." Written from the point of view of Holmes, it starts out in the usual way, and then ends rather lamely with no mystery presented or solved, but Holmes dead of incautiously (and improbably) sniffing excessively at a bottle of an anesthetic ("A.C.E.") he has asked Watson to bring with them on an errand.
Arthur Conan Doyle's son, Adrian Conan Doyle, wrote—in a joint effort with John Dickson Carr—twelve Sherlock Holmes short stories that were published under the title The Exploits of Sherlock Holmes in 1954.
Using his alternate name of H.F. Heard, Gerald Heard wrote three novels about a reclusive beekeeper in the English countryside who goes by the name of Mycroft; he's clearly intended to be Sherlock Holmes, but the books were written before the Doyle estate gave permission for other writers to use the name. The three stories are A Taste for Honey, Reply Paid and The Notched Hairpin. A Taste for Honey was adapted for American TV in 1955 as "Sting of Death," with Boris Karloff as Mr. Mycroft.
