The Oxford Murders

IN THIS SPELLBINDING MYSTERY TWO MATHEMATICIANS MUST JOIN FORCES TO STOP A SERIAL KILLER

A visiting Argentine graduate student finds his landlady—an elderly woman who helped decipher the Enigma Code during World War II—murdered in the parlor of her quiet Oxford home. Meanwhile, his mentor, the renowned Oxford logician Arthur Seldom receives an anonymous note bearing a circle and the words "the first of a series." As the murders and the list of suspects begin to pile up and more symbols are revealed, the pair is drawn further into a calculated and deadly game. It would appear that someone is using these deaths to illustrate a mathematical theorem. And it is up to these two unlikely detectives to solve the puzzle before the killer strikes again.
