Do ghosts exist? Perhaps, if, they have a murderous secret to tell . . . When newly-widowed Effie James is asked by her good friend, a professor of psychology, to help him with his latest book by participating in a local ghost-watching group, she is, at first, rather reluctant. But 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. So when the C-FITS are called in by a woman who is worried that her recently deceased mother might be haunting her old family home, Effie quickly finds herself thrown in at the deep end. And the eerie scent of lavender that mysteriously comes and goes in the old lady's bedroom is not the least of her worries. Effie slowly comes to suspect that the old lady might not have died of natural causes after all, and that her killer might not take very kindly to the idea of a nosy group of strangers poking their noses in.
