Volume three, the concluding part of Javier Marias’s acclaimed and evocative ‘novel in parts’

Jacques Deza is back in London and once again working for the secret intelligence agency run by Bertram Tupra. Deza finds himself forced to watch Tupra’s collection of incriminating videotapes of important public figures. The recordings document unconventional private lives - and horrific acts. The scenes enter him like a poison, contaminating everything good, yet he is powerless to counteract them. Set against a background of brutality, Poison, Shadow and Farewell asks whether violence can ever be justified and completes the extraordinary journey that has led us on a descent into hell and a re-emergence, not entirely unscathed, into life.
