The Cotswolds-based PR guru turned amateur sleuth returns for a series of comedic murder-mysteries based on the books by M.C. Beaton.

When former detective Robert and his school teacher wife Katy decide to make major changes to their lifestyle, they impulsively purchase a guest house in the Lake District where they plan to create a haven for holidaymakers. When Mark, a former colleague and friend, approaches the couple asking for their help in providing temporary housing for people needing protection from criminals, their idyllic guest house quickly becomes a safe house.

Alice's partner of 20 years, Harry, falls down the stairs and dies soon after the couple move into the dream home he designed. Alice discovers that some men, including her late ex, hide stuff that they don't want to deal with.
