Sherlock Holmes vs. Dracula (or The Adventures of the Sanguinary Count) is a Sherlock Holmes pastiche novel by Loren D. Estleman, originally published in 1978.
The novel is an account of Holmes' adventure facing off against Bram Stoker's Dracula and is presented as a revision of the Stoker novel, albeit with Sherlock Holmes present in the narrative.
The book has since been republished by I-Books and Titan Books, the latter under their Further Adventures of Sherlock Holmes banner.
British Fantasy Society called the book "one of the better" Dracula/Holmes crossovers. Kirkus Reviews called it "an example of the more cautious and studied sort of pseudo-Sherlock...Not that the purist approach makes Estleman's academic, short-story-sized notion any more prepossessing."
Estleman's novel was adapted for BBC Radio in 1981. It has since been rebroadcast numerous times.
