Stranger at the Dower House — Mary Kingswood

A widow moves into the long disused Dower House and makes a horrible discovery in the wine cellar.

Thirty-year-old widow Louisa Middlehope is determined to escape from her late husband's family and live life for herself for the first time. The tiny village of Great Maeswood offers her the peace and quiet her heart craves, and perhaps it might provide a little entertainment, too. But the house she has leased has been empty for a quarter of a century and who knows what secrets it holds?

Laurence Gage is still mourning his beloved wife, while raising his two children, and at forty, declining gently into a rather dull middle age. Until, that is, the intriguing Mrs Middlehope arrives in the village and upends his placid life. She's nothing at all like his perfect wife, but he's oddly drawn to her anyway and to his surprise, she seems to like him too. Whoever would have thought it? But what exactly is she looking for? Friendship, marriage -- or something else entirely?

This is a complete story with a happy ever after. Book 1 of a 6 book series.
