A movie production brings drama--and murder--to a close-knit New England village, forcing Riley Rhodes to scoop out the suspects.

Former CIA librarian and amateur sleuth Riley Rhodes is loving her fresh start as the manager of the Udderly Delicious Ice Cream Shop. The leaves are turning, tourists are leaf-peeping, and Penniman, Connecticut is putting finishing touches on the weekend long Halloween Happening. But the village is also buzzing. Former child star Cooper Collins is overseeing the production of a romantic comedy that's filming on the town green and his domineering socialite mother, Diantha, is planning her lavish Halloween themed wedding at her Inn on the Green. Her fiancé has run the Inn's kitchen for years, ably aided by his recent ex-wife, chef Mary Ann Dumas. An old friend of Riley's, Mary Ann turns to her when the bride requests a spooky ice cream wedding cake.

But the weekend takes a frightful turn when Diantha is found dead and suspicion falls on Mary Ann. The cast of potential suspects is long--each wedding guest had a chilling motive to kill the vicious heiress. Can Riley unmask the murderer before another guest ends up on ice?
