When Mr Collins is found stabbed to death in Lady Catherine de Bourgh's garden, simmering tensions are revealed beneath the elegant Regency surface of the Rosings estate.

The prime suspect is Mr Bennet, who was overheard arguing with Mr Collins over the entail of Longbourn in the days before the murder was committed, and who stands to benefit more than anyone from the Rector's death.

His daughter Mary uncovers a scandalous secret that holds the key to the murder. Can she prove her father's innocence in time to save him from the gallows?
