Audiobook four of the Secret Agent Granny series.
Ex-CIA agent Barbara Gold witnesses a woman being struck down by a car in broad daylight. It was no hit-and-run but plain, cold-blooded murder.
After some sleuthing, Barbara discovers the strangest fact yet about sleepy Cheerville, New England: There’s a nudist colony on the edge of town, and the victim was an active member. Barbara must go on the hardest mission of her career - bare her 70-year-old body for all to see - in order to solve another bizarre murder mystery.
