This thesis investigates the connection between the spiritualist movement and the literary ghost story, both of which came to prominence and mass popularity during the second half of the nineteenth century. While existing critical literature has viewed both phenomena as symptomatic of a wider Victorian fascination with the supernatural and the nature and possibility of an afterlife, little attention has been paid to the relationship between the two movements. By examining spiritualist literature alongside the work of both canonical and lesser-known writers, I attempt to address this area. My thesis argues for an understanding of the post-1850 ghost story as a dramatic representation of a new conception of the dead largely created by spiritualism, and reads the appearance, actions, behaviour and narratives of literary ghosts as an ongoing reflection and discussion of this idea.
