Forty-something single mother Cara Shelley is very content running the Happy Huffkin café in the grounds of a quirky stately home. But her daily routine is shaken up by the arrival of a guest at Tanton Towers: the flamboyant Lady Izzy. Ten years ago, Lady Izzy's nephew, the former chair of the local ghost society, died after a ghost hunt in the Towers' spooky subterranean grotto. Now, she plans to commemorate his life - and death - with a fresh hunt in the very same place. But the morning after the event, Cara makes a horrifying discovery. Unless spirits can kill, there's a murderer in their midst! Soon, the Towers is full of police, including the handsome but annoying DCI Andrew Mitchem. Can Cara keep her feelings in check and catch a cunning killer before she becomes the grotto's next ghost?
