Who is stalking Seffi Callard, the world's most fashionable spiritualist medium — now a paranoid recluse at her father's Cotswold home? Her old mentor Marcus Bacton, editor of an ailing journal of the paranormal, sends his assistant Grayle Underhill to try and establish the truth, unaware that he's thrusting them both into a nightmare. Along with Bobby Maiden, a police detective whose approach to his job has been changed forever by a near-death experience, they find themselves in the path of a vicious career-criminal for whom getting rich is less important than never getting dead.
