Agatha Raisin
Agatha Raisin and the Haunted House

A vengeful ghost comes back to haunt the living. Reports of a haunted house soon have Agatha snooping around, but it turns out the victim of the haunting is a universally disliked old biddy on whom someone is playing a practical joke. And then the old lady is murdered - but for Agatha, solving a crime is much more fun than hunting a ghost ! Very soon she's up to her usual tricks, involving the villagers, local police and, of course, her handsome new neighbour...
