of the Musgrave Ritual", and to some degree "The Adventure of the Three Students", that Holmes attended Oxford or Cambridge, although the question of which one remains a topic of eternal debate. Baring-Gould believed textual evidence indicated that Holmes attended both. The most influential "biography" of Holmes is Sherlock Holmes of Baker Street by Baring-Gould. Faced with Holmes' reticence about his family background and early life, Baring-Gould invented one for him. According to Baring-Gould, Sherlock Holmes was born in Yorkshire, the youngest of three sons of Siger Holmes and Violet Sherrinford. The middle brother, Mycroft, appears in the canon, but the eldest, Sherrinford Holmes, was invented by Baring-Gould to free Mycroft and Sherlock from the obligation of following Siger as a country squire. In reality, "Sherrinford Holmes" was one of the names Arthur Conan Doyle considered for his hero before settling on "Sherlock". Siger Holmes' name is derived from "The Adventure of the Empty House", in which Sherlock tells Watson that he spent some time pretending to be a Norwegian called Sigerson, which Baring-Gould reads literally as meaning "son of Siger." Sherrinford had a significant role in the Doctor Who crossover novel All-Consuming Fire by Andy Lane, which also featured a cameo by Siger. Some other notable versions of Holmes' parentage: Nicholas Meyer's The Seven-Per-Cent Solution reveals that Holmes's mother was cheating on his father, who then killed both her and himself. The film adaptation, also written by Meyer, further reveals that Moriarty was Holmes's mother's lover; in the novel, Moriarty is the man who brought young Sherlock the news of his parents' death. Either circumstance explains not only Holmes's career choice, but also (in an appropriately Freudian manner) his hatred of Professor Moriarty. Michael Harrison's I, Sherlock Holmes names his father as Captain Siger Holmes of the British East India Company. Fred Saberhagen's The Holmes-Dracula File suggests that Sherlock has some genetic parentage from the vampire Radu the Handsome, a younger brother of Vlad III Dracula, who had succeeded him as a ruler of Wallachia. Radu is not precisely Sherlock's father, however, as vampires (in Saberhagen's Dracula series) are incapable of conceiving children. Rather, Sherlock's unfaithful mother was having marital relations with his father at the same time as she was carrying on an affair with the vampire. Her affair included drinking Radu's blood—which would include his genetic material. So Sherlock (and, in Saberhagen's novel, his unnamed identical twin
