A gripping tale of revenge and rivalry from the author of The Oxford Murders Argentinean author Guillermo Martínez's work appeals to fans of both literary fiction and mysteries. Now, with this new tale of psychological suspense, Martínez is poised to expand on the success of The Oxford Murders. The narrator is an up-and-coming young writer who has little in common with Kloster – a literary giant whose disturbing crime novels dominate the bestseller lists. However, they have both, at one time, employed the secretarial services of the alluring Luciana B. Out of the past, Luciana makes a desperate plea to the young writer. She thinks that Kloster is slowly killing off everyone close to her – can he help before her grandmother and younger sister are murdered? While the narrator suspects her misfortunes have driven her mad, Kloster has a powerful motive; and eerie parallels surface between the murders in Kloster's books and the real-life deaths surrounding Luciana. As the body count multiplies, the question arises: Can words really kill? Fans of both Alfred Hitchcock and Carlos Ruiz Zafón will be thrilled with Martínez's literary murder mystery

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
