a clergyman's family. Also in March, the Shelleys moved with Claire and Alba to Albion House at Marlow, Buckinghamshire, a large, damp building on the river Thames. There Mary Shelley gave birth to her third child, Clara, on 2 September. At Marlow, they entertained their new friends Marianne and Leigh Hunt, worked hard at their writing, and often discussed politics. Early in the summer of 1817, Mary Shelley finished Frankenstein, which was published anonymously in January 1818. Reviewers and readers assumed that Percy Shelley was the author, since the book was published with his preface and dedicated to his political hero William Godwin. At Marlow, Mary edited the joint journal of the group's 1814 Continental journey, adding material written in Switzerland in 1816, along with Percy's poem "Mont Blanc".
