Nobody, but nobody comes to stay in Maple Bay after September, so when a mysterious stranger comes to town and starts nosing around, Allison and Peter Martindale are naturally suspicious.
And worried. Their parents own the 100-year-old Coach House Inn where Mr. Moon is staying, and if he's a bad guy, the Martindales are in deep trouble. The Inn is already losing money they can't afford to lose their reputation as well.
