- Uncle Silas is a Victorian Gothic mystery-thriller novel by the Irish writer J. Sheridan Le Fanu. It is notable as one of the earliest examples of the locked room mystery subgenre. It is not a novel of the supernatural, but does show a strong interest in the occult and in the ideas of Emanuel Swedenborg, a Swedish scientist, philosopher and Christian mystic. The novel is a first person narrative told from the point of view of the teenaged Maud Ruthyn, an heiress living with her sombre, reclusive father Austyn Ruthyn in their mansion at Knowl. She gradually becomes aware of the existence of Silas Ruthyn, a black sheep uncle whom she has never met, who was once an infamous rake and gambler but is now apparently a reformed Christian. Silas's past holds a dark mystery, which she gradually learns from her father and from her worldly, cheerful cousin Lady Monica: the suspicious suicide of a man to whom Silas owed an enormous gambling debt, which took place within a locked, apparently impenetrable room in Silas's mansion at Bartram-Haugh. Austyn is firmly convinced of his brother's innocence; Maud's attitude to Uncle Silas wavers repeatedly between trusting in her father's judgment, and growing fear and uncertainty. Austyn Ruthyn obscurely asks Maud if she is willing to undergo some kind of "ordeal" to clear Silas's name. She assents, and shortly thereafter her father dies. It turns out that he has added a codicil to his will: Maud is to stay with Uncle Silas until she comes of age. If she dies while in her minority, the estate will go to Silas. Despite the best efforts of Lady Monica and Austyn's executor, Maud is forced to spend the next three and a half years of her life at Bartram-Haugh. Life at Bartram-Haugh is initially strange but not unpleasant, despite ominous signs such as the uniformly unfriendly servants and a malevolent factotum of Silas's, the one-legged Dickon Hawkes. Silas himself is a sinister, soft-spoken man who is openly contemptuous of his two children, the loutish Dudley and the untutored but friendly Milly. Silas is subject to mysterious catatonic fits which are attributed by his doctor to his massive opium consumption. Gradually, however, the trap closes around Maud: it is clear that Silas is attempting to coax or force her to marry Dudley. When that plan fails, and as the time-limit of three-and-a-half years begins to shrink, it becomes clear that more violent methods may be used to ensure that Silas gains control of the Ruthyn estate....
