Back from Rome, their ninth frantic escapade mercifully ended, Penny and Sir Toby decide it's high time for a rest. When they get the chance to return to Cape Cod, the scene of their second misadventure, they can't resist. But they soon have a dead body on their hands, and a puzzle-within-a-puzzle to decipher as well.
