Books by Guillermo Martínez

From the author of the bestselling The Oxford Murders comes a stylish and gripping new crime story that will be loved by readers of Umberto Eco.

Art imitates life. Or does it? One sleepy Sunday morning in Buenos Aires, the protagonist of Martinez's brilliant new mystery finds himself unexpectedly tangled up in the story of Luciana, a former authors' assistant whom he has not seen for at least ten years, and Kloster, a rival writer - only far more successful; bestselling, in fact. What he discovers will make him question everything he had always believed - taken for granted - about chance and calculation, cause and effect.Luciana is desperate. In the decade since she last had anything to do with either of the writers, nearly all her close family have died, in highly unusual circumstances. And Luciana or her sister could be next. Luciana's convinced that her one-time employer Kloster is behind the deaths, punishing her for her part in the break-up of his marriage in a murderous frenzy of revenge worthy of one of his own prodigiously successful crime novels. But which comes first, murder or novel? Clever and gripping, THE BOOK OF MURDER is a chilling crime story in which the line between fact and fiction suddenly seems blurred.

On a balmy summer's day in Oxford an old lady who once helped decipher the Enigma Code is killed. After receiving a cryptic anonymous note containing only the address and the symbol of a circle, Arthur Seldom, a leading mathematician, arrives to find the body. Then follow more murders - an elderly man on a life-support machine is found dead with needle marks in this throat; the percussionist of an orchestra at a concert at Blenheim Palace dies before the audience's very eyes - seemingly unconnected except for notes appearing in the maths department, for the attention of Seldom. Why is he being targeted as the recipient of these coded messages? All he can conjecture is that it might relate to his latest book, an unexpected bestseller about serial killers and the parallels between investigations into their crimes and certain mathematical theorems. It is left to Seldom and a postgraduate mathematics student to work out the key to the series of symbols before the killer strikes again.
