Agatha Raisin, snug and warm in her Carsley cottage, has that same old feeling-boredom-until a report of a haunted house sends her and new neighbor, handsome Paul Chatterton, to investigate. Suddenly, middle-aged Agatha is aglow with romance and excitement.

But the glow fades fast. It turns out Paul is a cad. The victim of the haunting is a universally disliked old biddy. And the ghost is most likely someone playing a dirty trick. Then an old lady is soon found murdered. But never fear! For Agatha, solving a homicide is more fun than hunting a ghost. She quickly has a theory and a risky scheme. And she is about to make a startling discovery which can be her greatest triumph...or leave her heartbroken, in trouble with the police, and in danger of losing her reputation-or her life.
