Dickens' final novel, left unfinished at his death in 1870, is a mystery story much influenced by the 'Sensation Novel' as written by his friend Wilkie Collins. The action takes place in an ancient cathedral city and in some of the darkest places in Victorian London. Drugs, disappearances, sexual obsession, disguise and a possible murder are among the themes and motifs. A sombre and menacing atmosphere, a fascinating range of characters and Dickens' usual command of language combine to make this an exciting and tantalising story. Also included in this volume are a number of unjustly neglected stories and sketches, with subjects as different as murder, guilt and childhood romance.
