Norfolk, 1813. In the quiet Waveney Valley, the body of a woman - Mary Tyrell - is staked through the heart after her death by suicide. She had been under arrest for the suspected murder of her newborn child.
Inspired by the real events of the Vardo storm of 1617, The Mercies is a story about how suspicion can twist its way through a community, and a love that may prove as dangerous as it is powerful.
