It's autumn in Vermont, and the mountains are ablaze with color, just in time for Stonebridge's annual harvest festival. The village is swarming with leaf-peeping tourists, and the celebration is off to a jubilant start as residents gather for their favorite kick-off event: a masquerade party on the village green.

Photographer Bobbie Brooks vows to leave the investigation to the professionals until a tearful plea from a friend causes her to shift her focus from merriment to murder.

But as everything comes into focus, Bobbie finds herself in danger once again. Can she unmask the killer before the killer zooms in on her?
