The Donaldson Case

Please note that this is a novella length story (around 25,000 words). The story is complete, no cliffhanger ending. Janet and Joan Markham are settling in to running their bed and breakfast and their new life in Doveby Dale. Janet is excited to discover a hidden panel and a piggy bank that holds a key. She's eager to find out what the key is for, but Joan isn't really interested. Joan is busy spending time with their handsome neighbour, Michael Donaldson. But Michael finds himself being investigated by the police after some problems at the local chemist shop and Janet is surprised to find that Joan is more anxious to snoop than she is. Can the sisters find time to snoop while the house is full of guests? Can they clear Michael's name? Can Janet find a lock to open with her key?
