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.

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.

Mathematics student G is trying to resurrect his studies, which is proving difficult as he finds himself - and not for the first time - drawn into investigating a series of mysterious crimes.When Kristen, a researcher hired by the Lewis Carroll Brotherhood, makes a startling new discovery concerning pages torn from Caroll's diary, she hesitates to reveal to her employers a hitherto unknown chapter in his life. Oxford would be rocked to its core if the truth about Lewis Carroll's relationship with Alice Liddell - the real Alice - were brought to light.After Kristen is involved in a surreal accident and members of the Brotherhood are anonymously sent salacious photographs of Alice, G joins forces with Kristen as they begin to realise that dark powers are at work. More pictures are received, and it becomes clear that a murderer is stalking anyone who shows too much interest in Carroll's life. G must stretch his mathematical mind to its limits to solve the mystery and understand the cryptic workings of the Brotherhood. Until then, nobody, not even G, is safe. A thrilling novel from the author of The Oxford Murders, inspired by true, strange stories from Caroll's life, The Oxford Brotherhood is sure to make you curiouser and curiouser.
