Anglemore Park is the ancestral home of Lady Emily Hargreave's husband Colin. But the stately calm of country life is destroyed when their neighbor, the Marquess of Montagu, bursts through the French doors from the garden and falls down dead in front of the shocked gathering. But who has a motive for murdering the young aristocrat? The lovely cousin who was threatened by his engagement, the Oxford friend he falsely accused of cheating, the scheming vicar's daughter he shamelessly seduced or the relative no one knew existed who appears to claim the Montagu title? Who is the mysterious woman seen walking with him moments before he was brutally attacked?
