My secrets-the secrets that everyone has-are here, in black and white.'

Patricia Highsmith's diaries and notebooks offer an unparalleled, unforgettable insight into the life and mind of one of the 20th century's most talented, complex and fascinating writers.

Posthumously discovered in Highsmith's linen cupboard and edited down from 56 thick spiral notebooks by her devoted editor, Anna Von Planta, this one-volume assemblage of her diaries and notebooks traces Highsmith's mesmerising double life.

The diaries show Highsmith's unwavering literary ambitions - coming often at huge personal sacrifice. We see her writing the books that would make her name, including the Ripley novels which mark the apotheosis of the psychological thriller, and The Price of Salt (later adapted into the 2015 film Carol), one of the first mainstream novels to depict two women in love.

In these pages, we see Highsmith reflecting on good and evil, loneliness and intimacy, sexuality and sacrifice, love and murder. We see her tumultuous romantic relationships play out alongside her acquaintances with other writers.

Written in her inimitable and dazzling prose and offering all the pleasures of Highsmith's novels, these are one of the most compulsively readable literary diaries to be published in generations - and yield, at last an unparalleled, unfiltered, unforgettable picture of this enigmatic, iconic, trailblazing author's true self.
