The Rivals of Sherlock Holmes

Today, the figure of Sherlock Holmes towers over detective fiction like a colossus-but it was not always so. Edgar Allan Poe's French detective Dupin, the hero of "The Murders in the Rue Morgue", anticipated Holmes' deductive reasoning by more than forty years with his "tales of ratiocination". In A Study in Scarlet, the first of Holmes' adventures, Doyle acknowledged his debt to Poe-and to Émile Gaboriau, whose thief-turned-detective Monsieur Lecoq debuted in France twenty years earlier. If "Rue Morgue" was the first true detective story in English, the title of the first full-length detective novel is more hotly contested. Two books by Wilkie Collins-The Woman in White (1859) and The Moonstone (1868)-are often given that honour, with the latter showing many of the features that came to identify the genre: a locked-room murder in an English country house; bungling local detectives outmatched by a brilliant amateur detective; a large cast of suspects and a plethora of red herrings; and a final twist before the truth is revealed. Others point to Mary Elizabeth Braddon's The Trail of the Serpent (1861) or Aurora Floyd (1862), and others still to The Notting Hill Mystery (1862-3) by the pseudonymous "Charles Felix".
