For over 200 years, the Cranberry family has owned property in the town that bears its name in Southern Connecticut near the shore of the Long Island Sound. For all that time, the true ownership of that property has been contested by one group or another. When Chester, the initial owner of the farm that grew into this sprawling estate, was murdered in 1832, everyone believed the murderer was his wife, Elcira Cranberry. Elcira was locked in a potting shed at the time, and she was found to have no key which would allow her to get out and lock herself back in. So, the lack of evidence, and the lack of any other evidence, resulted in a cold case, which, after two-hundred years, has grown very cold, indeed.

Nearly two centuries later, in 2024, the key turns up in a rose garden on the property, resurrecting the previously deceased speculation that Widow Elcira could have murdered her husband. Mildred Cranberry Smith, the current owner had promised her daughter that she would leave her entire estate in Old Cranberry to her granddaughter, Maggie, when Maggie married. So, here we are. Maggie is engaged to the son of a property developer who wants to turn the property into a luxury townhouse community, and a woman claiming to be a direct descendant of the woman Chester raped believes she can wrestle away the property from Mildred and claim it as hers. Meanwhile, Mildred’s aunt who dug up the key in her garden, enlists the support of the Old Cranberry Ladies Garden Club to help solve the case. But when Auntie uncovered the key, she dug up something else as well. Enter Elcira Cranberry, the ghost of the woman accused of killing her husband 200 years ago. Will the key prove that she did it and void the inheritance? There is a ghost of a chance it will.
