Philip Larkin met Monica Jones at University College Leicester in autumn 1946, when they were both twenty-four; he was the newly-appointed assistant librarian and she was an English lecturer. In 1950 Larkin moved to Belfast, and thence to Hull, while Monica remained in Leicester, becoming by turns his correspondent, lover and closest confidante, in a relationship which lasted over forty years until the poet's death in 1985.

This remarkable unpublished correspondence only came to light after Monica Jones's death in 2001, and consists of nearly two thousand letters, postcards and telegrams, which chronicle - day by day, sometimes hour by hour - every aspect of Larkin's life and the convolutions of their relationship.
