In 1592, Prague is a relatively safe refuge for Jews who live within the gated walls of its ghetto. But the peace is threatened when a young Christian girl is found with her throat slashed in a Jewish shop on the eve of Passover. Charged with blood libel, the shopkeeper and his family are arrested, and all that stands in the way of a rabid Christian mob is a clever Talmudic scholar, newly arrived from Poland, named Benyamin Ben-Akiva. Granted just three days to bring the true killer to justice-hampered by rabbinic law, with no allies or connections, and only his wits, knowledge, and faith to guide him-Benyamin sets off on a desperate search for answers. Following a twisting trail from the streets to the shul, from the forbidden back rooms of a ghetto brothel to the emperor Rudolf II's lavish palace, he will dare the impossible-and commit the unthinkable-to save the Jews of Prague . . . and himself.
