Man and Wife (1870) combines the fast pace and sensational plot structure of Collins's most famous novels with a biting attack on the inequitable marriage laws in Victorian Britain. At its centre is the plight of a woman who fears that the archaic marriage laws of Scotland and Ireland may have forced her into committing unintentional bigamy. As the novel progresses, the atmosphere grows increasingly sinister when the setting moves from a country house to a London suburb and a world of confinement, plotting, and murder.
