The Zachery Case

"Janet Markham is looking forward to Edward Bennett’s arrival at the bed and breakfast she runs with her sister Joan. She and Edward have been seeing one another for a while now, and he’s meant to be retiring and moving to Doveby Dale for good.
Joan is just anxious to get the carriage house cleared out so that she can turn it into a guest room. When Janet moves the last few boxes and finds a skeleton, though, Joan’s plans get put on hold as the sisters find themselves caught up in a murder investigation."
