If there's one character in Bram Stoker's novel Dracula as fascinating as the arch vampire himself, it's R.M. Renfield the zoophagous patient in Dr. Seward's mental hospital, who has fallen under the vampire's spell. But Stoker provides no explanation of how Renfield came to be imprisoned, nor of the origins of his strange relationship with his Master. Marty Ross's audio drama imagines a whole back story for the character - the story of a tragically ordinary Victorian shopkeeper, stuck looking after ageing parents and prone to a furtive fascination with blood.
