Roberts, Nora. Lost bride trilogy #1

1806. Astrid Poole is murdered on her wedding day. Her last words - a promise to her husband never to leave him. After finding her fianč in a compromising position with her cousin, Sonya MacTavish needs an escape. When a lawyer turns up on her doorstep out of the blue with news that she has inherited a beautiful Victorian house, Sonya thinks maybe this is just the change of scene she needs. The house - nicknamed Lost Bride manor - is beautiful, the setting idyllic and the local town offers Sonya the smalltown comforts she craves after life in a big city. So what if there are sometimes shadows in the windows, objects move of their own accord and music starts playing out of nowhere. Sonya can live with the house being a little haunted. But things soon start to take a darker turn and it becomes clear that Sonya has inherited far more than a house. She has inherited a centuries-old curse, and a puzzle she must solve if there is any hope of breaking it
