Nosferatu

Thomas Hutter (Jonathan Harker in Stoker's novel) lives in the fictitious German city of Wisborg. His employer, Knock (loosely based on Renfield), sends Hutter to Transylvania  to visit a new client named Orlok. Hutter entrusts his loving wife Ellen to his good friend Harding and Harding's sister Ruth, before embarking on his long journey.
