Do ghosts exist? Perhaps, if they have a murderous secrdt to tell. Newly-widowed Effie James is asked by her old friend Duncan, a psychology professor, to help him with his latest book. Her task is to join the C-Fits, a paranormal investigation team, on their ghost-watching vigils and report back to Duncan. Corwin Fielding, the attractive and erudite leader of the paranormal researchers has no objections to an ‘impartial’ observer on his team, and the others in the group are a friendly and welcoming bunch. The C-Fits are called in by Isabel Atkins. She is worried that her recently deceased mother might be haunting her old family home. Effie quickly finds herself thrown in at the deep end.
