In the autumn of 1900, Adam Blackwood, a young bank clerk, travels to take up new employment in the small village of Cedar Moor, near Manchester. As he steps from the train he experiences a sense of unease as sees the shadow of a small, cloaked figure moving in the stairwell which exits the station. Over the next few months, he becomes haunted by what he perceives to be the spirit of a young girl. But what is her purpose? And what is her connection with the grave of the unknown Sam Blackwood, whose headstone records his date of death as over a year into the future? As those around him begin to doubt his sanity, Adam struggles against a gathering storm, determined to discover the identity of the Girl on the Moor.
