The Discreet Retrieval Agency is doing a brisk holiday business of retrieving lost parcels, grandmas, and stolen wreaths. But with their main squeezes Ralph and Jimmy once more on the back burner, both Lola and Berta pine for a holiday out of New York City. So when they receive a mysterious Christmas card requesting that they retrieve an antique ring at a family gathering in Maple Hill, Vermont, they jump at the chance. Sure, the card is signed Anonymous and it's vaguely threatening, but it's Vermont. In Maple Hill, several estranged members of the wealthy Goddard family gather. And no sooner do Lola and Berta recover the ring - from Great-Aunt Cressida Goddard's arthritic finger - than Mrs. Goddard goes toes-up, poisoned by her Negroni cocktail on ice. When the police arrive, Lola and Berta are caught-red-handed with the ring, and it becomes clear that they were in fact hired not for their cracker-jack retrieving abilities, but to be scapegoats for murder. With no choice but to unmask the killer or be thrown in the slammer, Lola and Berta's investigations lead them deep into the secrets of Maple Hill. In a breathless pursuit along a snowy ridge, with a lovelorn Norwegian ski instructor and country bumpkin hooch smugglers hot on their heels, Lola and Berta must find out once and for all who's nice and who's naughty.
