The Bloody City
This novel follows on from The Sins of the Father (HNR 49), now also reissued by The Mystery Press, and takes place only a few days later. It is May 1217, and young Edwin Weaver, having come to the attention of his politically suspect lord by his acute memory and deductive and arithmetical skills, is now carried off to the besieged city of Lincoln. French and rebel forces hold Lincoln, except for the castle.
The relief force into which Edwin has been called up, commanded by King Henry III’s Regent, William Marshal, is approaching. Edwin is sent into Lincoln to make contact with loyalist citizens within. Having had to turn detective in the previous novel, Edwin must now turn spy, but he finds himself dealing with murders and with the question of who is treasonably aiding the French and rebels.
Espionage, mystery, and romance combine to make The Bloody City an entertaining read, although you may find it helpful to read The Sins of the Father first for more of the backstory.
