The Essex Serpent : a novel
(Book)

When Cora Seaborne's brilliant, domineering husband dies, she steps into her new life as a widow with as much relief as sadness: her marriage was not a happy one. Wed at nineteen, this woman of exceptional intelligence and curiosity was ill-suited for the role of society wife. Seeking refuge in fresh air and open space in the wake of the funeral, Cora leaves London for a visit to coastal Essex, accompanied by her inquisitive and obsessive eleven-year old son, Francis, and the boy's nanny, Martha, her fiercely protective friend. While admiring the sites, Cora learns of an intriguing rumor that has arisen further up the estuary, of a fearsome creature said to roam the marshes claiming human lives. After nearly 300 years, the mythical Essex Serpent is said to have returned, taking the life of a young man on New Year's Eve. A keen amateur naturalist with no patience for religion or superstition, Cora is immediately enthralled, and certain that what the local people think is a magical sea beast may be a previously undiscovered species.
