Caitlin Thomas (née Macnamara; 8 December 1913 – 31 July 1994) was an author and the wife of the poet and writer Dylan Thomas. Their marriage was a stormy affair, fuelled by alcohol and infidelity, though the couple remained together until Dylan's death in 1953. After his death, she wrote the book Leftover Life to Kill, an account of her self-exile to Italy. She paints a portrait of a grieving widow seeking solace in distance, a younger lover, and alcohol.
