The place they rented, Casa Magni, was a former boathouse between the fishing village of Lerici and the even smaller hamlet of San Terenzo. ‘The sea came up to the door,’ Mary Shelley later wrote. ‘A steep hill sheltered it behind.’ As well as Mary, her husband, their surviving son and their servants, the household included their new friends Edward and Jane Williams, their children and servants, and Mary’s half-sister, Claire Clairmont.
