"London. May, 1556. Hal Westmecott, one of the city's most feared executioners, reckons Jack Blackjack owes him a favour - and now he's come to collect his dues. Hal has ordered Jack to track down his long-lost son and, although Jack believes he's been set an impossible task, he's in no position to refuse. But when Jack's search draws him to the attention of a ruthless nobleman, a dead priest's vengeful brother and finally to a bloodstained body in a filthy lodging house, he comes to realize he is an unwitting pawn in a mesh of schemes dreamed up by the most powerful people in England. Just who is a friend, who is a foe - and will Jack escape with his life intact?"--Publisher description.
