There must be a victim. A suspect. A detective. The rest is just shuffling the sequence. Expanding the permutations. Grant McAllister, a professor of mathematics, once sat down and worked them all out – calculating the different orders and possibilities of a mystery into seven perfect detective stories he quietly published. But that was thirty years ago. Now Grant lives in seclusion on a remote Mediterranean island, counting the rest of his days.Until Julia Hart, a sharp, ambitious editor knocks on his door. Julia wishes to republish his book, and together they must revisit those old stories: an author hiding from his past, and an editor, keen to understand it.But there are things in the stories that don’t add up. Inconsistencies left by Grant that a sharp-eyed editor begins to suspect are more than mistakes. They may be clues, and Julia finds herself with a mystery of her own to solve.

    In medieval Cambridge, England, four children have been murdered. The crimes are immediately blamed on the town's Jewish community, taken as evidence that Jews sacrifice Christian children in blasphemous ceremonies. To save them from the rioting mob, the king places the Cambridge Jews under his protection and hides them in a castle fortress. King Henry II is no friend of the Jews-or anyone, really-but he is invested in their fate. Without the taxes received from Jewish merchants, his treasuries would go bankrupt. Hoping scientific investigation will exonerate the Jews, Henry calls on his cousin the King of Sicily-whose subjects include the best medical experts in Europe-and asks for his finest "master of the art of death," an early version of the medical examiner. The Italian doctor chosen for the task is a young prodigy from the University of Salerno. But her name is Adelia-the king has been sent a "mistress" of the art of death. Adelia and her companions-Simon, a Jew, and Mansur, a Moor-travel to England to unravel the mystery of the Cambridge murders, which turn out to be the work of a serial killer, most likely one who has been on Crusade with the king. In a backward and superstitious country like England, Adelia must conceal her true identity as a doctor in order to avoid accusations of witchcraft. Along the way, she is assisted by Sir Rowley Picot, one of the king's tax collectors, a man with a personal stake in the investigation. Rowley may be a needed friend, or the fiend for whom they are searching. As Adelia's investigation takes her into Cambridge's shadowy river paths and behind the closed doors of its churches and nunneries, the hunt intensifies and the killer prepares to strike again . .
