Toni Holmes is the best gluten-free baker in Oiltop, Kansas-okay, she’s the only one-but when her grandmother becomes a murder suspect, she’s more concerned with keeping Grandma free… When Toni’s beloved-and eccentric-grandma Ruth is arrested for the murder of her archenemy, Lois Striker, it’s time for a senior moment of truth. Telltale tracks from a scooter like the one Grandma Ruth rides lead the police to suspect the outspoken oldster, but Toni knows her grandmother wouldn’t burn a cookie, let alone extinguish a life. In fact, the case has Grandma more revved up than her infamous scooter. A former investigative journalist, she decides to solve the murder herself-with help from Toni-by digging up long-buried town secrets. But as Grandma scoots in where others fear to tread, Toni needs to make sure she not only stays out of jail but out of harm’s way…
