Based on a true story - Delphine de Vigan

What would you do if your closest friend tried to steal your life? 'Combining the allure of Gone Girl with the sophistication of literary fiction, Based on a True Story is a creepy but unapologetically clever psychological thriller' Independent Today I know that L. is the sole reason for my powerlessness. And that the two years that we were friends almost made me stop writing for ever.Overwhelmed by the huge success of her latest novel, exhausted and unable to begin writing her next book, Delphine meets L. L. is the kind of impeccable, sophisticated woman who fascinates Delphine; a woman with smooth hair and perfectly filed nails, and a gift for saying the right thing. Delphine finds herself irresistibly drawn to her, their friendship growing as their meetings, notes and texts increase. But as L. begins to dress like Delphine, and, in the face of Delphine's crippling inability to write, L. even offers to answer her emails, and their relationship rapidly intensifies. L. becomes more and more involved in Delphine's life until she patiently takes control and turns it upside down: slowly, surely, insidiously. Based on a True Story is a chilling novel of suspense that will leave you questioning the truth and its significance long after you have turned the final page.

Delphine de Vigan is French and lives in Paris. She has published several novels for adults. No and Me was awarded the Prix des Libraires 2008 (The Booksellers' Prize) in France.

The latest literary sensation ... It has people in a word-of-mouth frenzy I've not seen since Gone Girl ... De Vigan's description of a close female friendship is a compulsive but agonising read

This is that rare beast - a fine thriller and a potential literary sensation. Patricia Highsmith would have been proud. Don't miss it
Daily Mail

All writing is constructed on shifting sands, but I've never read a book that makes the complex relationship between reality and fiction both as visible, and at the same time so opaque, as here. I was captivated. Combining the allure of Gone Girl with the sophistication of literary fiction, Based on a True Story is a creepy but unapologetically clever psychological thriller that also aces the Bechdel test
