An Eye for an Eye is a novel by Anthony Trollope written between 13 September and 10 October 1870, but held back from publication until August 1878 when serialization began in the Whitehall Review. Publication in the form of a two volume novel was timed to coincide with the issue of the final serialized episodes in January 1879. It is one of five novels which Trollope set mainly in Ireland, although much of the story takes place at Scroope Manor in Dorsetshire, the ancestral home of the ageing Earl of Scroope.
