This is better described as “Mystery of the Mink Hoodwink.” Nancy, after nearly getting taken out by a rogue car, discovers that a mysterious Mrs. Channing has been selling local ladies sweet furs and worthless stock certificates. Then she finds that they’re posing as her! She’s also tapped to help her dad solve a case in Montreal, and they meet a trapper who looks like someone who couldn’t decide between cosplaying as Daniel Boone or Santa. Grab the boys and head to the Adirondacks, it’s villain catching time!
