Cassie Miller returned to her sleepy hometown in the Berkshires to start over as the new postmistress. But she soon finds that dead letters are nothing compared to murder victims . . . With a massive storm about to hit North Ashcot, Massachusetts, threatening floods and widespread wind damage, Cassie is forced to close up the post office along with the rest of the local business owners and residents, who are battening down the hatches and bracing themselves for the worst. Although the storm proves not to be as bad as predicted, fabric shop owner Daisy Harmon is found dead, seemingly killed by a fallen branch. But the police quickly determine that her death had nothing to do with foul weather and everything to do with foul play. After Daisy's widowed husband approaches her to help solve his wife's murder, Cassie vows to find the killer before another innocent victim is taken by storm.
