New Zealand-born Katherine Mansfield was one of the most original and influential writers of her generation. Her life also inspired two unlikely fans. Decades after her death, a father and son have each become obsessed by her. What can this woman's life mean to them? Is she merely an object of admiration, or is she a focus for darker impulses of ambition and self-seeking? Inspired by the true story of the theft of some of Katherine Mansfield's most poignant letters, Thieves investigates both the life of this remarkable creative spirit, and the seductive facility with which desire can breed deception.
