Murder Among the Pines

Small-town police chief Maxine "Max" Benson is just settling into her new life when her ex appears on the scene. Apparently, he and his new young lover just happen to be visiting her area on holiday. Max left her marriage and the Toronto police to become chief in Port Ainslie, where she runs a three-person department with few problems and enjoys a different pace of life. That's all about to change when Max's ex-husband is accused of killing his young lover right in Max's own backyard.
It seems that only Max's superior detection abilities can save him from an almost certain conviction. This is the third book in the Maxine Benson mystery series.
