The novel is a 19th-century semi-epistolary one. Armadale is a novel by Wilkie Collins, first published in 1864–66. It is the third of Wilkie Collins’s four 'great novels' of the 1860s: after The Woman in White (1859–60) and No Name (1862), and before The Moonstone (1868). Some linking passages consist of letters between the various characters, or of extracts from Lydia's journal, but the great majority of the text narrates the events as they occur.
