Nancy Hunter and her grandmother Jane Hunter run the Dedley Endings Bookshop, selling crime, thriller and mystery books, in a small, quiet Cotswold village where nothing ever happens... That is, until the wealthy and reclusive Roth family open up their mansion for the first time in thirty years, inviting the people of Dedley End to a lavish engagement party. While everyone is thrilled to finally look around the mansion on the hill, the festivities are quickly cut short when beautiful Lucy, recently married to young Harry Roth, is found dead after being pushed over the first-floor balustrade. Nancy and Jane decide to investigate - after all, not only do they own a crime themed bookshop, they were also both named after famous literary detectives - but soon wonder if they've taken on more than they can handle.
