This article considers the later career of the Irish Gothic author, Bram Stoker (1847–1912), and interrogates the publishing history of his penultimate work, the non-fictional study, Famous Impostors (1910). Making use of the unpublished correspondence of Stoker’s British and US publishers, it charts the development of the work from its inception (where Stoker was actually paid the same amount as his agent), through the period of its writing, when Stoker was seriously ill, to its revision and final publication. To date, Famous Impostors remains probably the least studied of the author’s works. This article will address that gap in critical knowledge, as well as presenting new biographical materials associated with the author and his experience of publishing in the early twentieth century.
