Who Killed Mona Lisa? — Carole Bugge

In the third book of her popular whodunit series, mystery editor Claire Rawlings and her twelve-year-old sidekick, Meredith Lawrence, visit a Massachusetts inn where murder is a popular way to pass the time....

On the advice of her editor-in-chief, Claire visits a cozy New England inn to spend Thanksgiving weekend with her new boyfriend, Wally Jackson-and young Meredith tags along, of course.

But when bodies start turning up, the dead letters become live clues to the inn's dark past--and even darker present....
