In February 2016, Ahmed Naji was sentenced to two years in prison for "violating public modesty," after an excerpt of his novel Using Life reportedly caused a reader to experience heart palpitations. Naji ultimately served ten months of that sentence, in a group cell block in Cairo's Tora Prison.

Rotten Evidence is a chronicle of those months. Through Naji's writing, the world of Egyptian prison comes into vivid focus, with its cigarette-based economy, home-made chess sets, and well-groomed fixers. Naji's storytelling is lively and uncompromising, filled with rare insights into both the mundane and grand questions he confronts.

How does one secure a steady supply of fresh vegetables without refrigeration? How does one write and revise a novel in a single notebook? Fight boredom? Build a clothes hanger? Negotiate with the chief of intelligence? And, most crucially, how does one make sense of a senseless oppression: finding oneself in prison for the act of writing fiction. Genuine and defiant, this book stands as a testament to the power of the creative mind, in the face of authoritarian censorship.
