小说描写了一件争夺遗产的诉讼案，由于司法人员从中营私、徇讦，竟使得案情拖延20年。在一个偶然机会里，男爵夫人的私生女艾瑟·萨莫森（Esther Summerson）被那一群律师得知，于是追根究柢的律师借此威胁男爵夫人，甚至整死一名流浪少年，男爵夫人被迫离家出走，死于一场暴风雪。其中一名律师被他所利用的人杀害。这20年期间申诉者居住在荒凉山庄，主人约翰·詹狄士（John Jarndyce）成为一对表兄妹的监护人，等待法官做最后的判决，最后整笔遗产正好全数支付有关的法律诉讼费用，跟诉讼案有关的人死的死，发疯的发疯。

Bleak House was first published as a serial between March 1852 and September 1853, and it is one of Charles Dickens's major novels. The novel has many characters and several sub-plots, and the story is told partly by the novel's heroine, Esther Summerson, and partly by an omniscient narrator. At the centre of Bleak House is the long-running legal case, Jarndyce and Jarndyce, which came about because someone wrote several conflicting wills. This legal case is used by Dickens to satirize the English judicial system, and he makes use of his earlier experiences as a law clerk, and as a litigant seeking to enforce copyright on his earlier books.
