Murder on the cliffs: a Daphne Du Maurier mystery

Walking on the cliffs in Cornwall, Daphne du Maurier stumbles upon the drowned body of a beautiful woman, dressed only in a nightgown, her hair strewn along the rocks, her eyes gazing up to the heavens. Daphne soon learns that the mysterious woman was engaged to marry Lord Hartley of Padthaway, an Elizabethan mansion full of intriguing secrets. As the daughter of the famous Sir Gerald du Maurier, Daphne is welcomed into the Hartley home, but when the drowning turns out to be murder, Daphne determines to get to the bottom of the mysteries of Padthaway--in part to find fresh inspiration for her writing, and in part because she cannot resist the allure of grand houses and long buried secrets.
