Leeds, England, Christmas Eve, 1890. DI Tom Harper is looking forward to a well-earned rest. But it's not to be. A young man has been found stabbed to death in the city's poverty-stricken Jewish district, his body carefully arranged in the shape of a cross, two bronze pennies covering his eyes. Could someone be pursuing a personal vendetta against the Jews?

Harper's investigations are hampered by the arrival of Capitaine Bertrand Muyrere of the French police, who has come to Leeds to look into the disappearance of the famous French inventor Louis Le Prince, vanished without trace after boarding a train to Paris.

With no one in the close-knit Jewish community talking to the police and with tensions rising, DI Harper realizes he'll have to resort to more unorthodox methods in order to unmask the killer.
