The Keeper of Lost Things by Ruth Hogan. "Anthony is an elderly man whose fiancee died the day he lost a medallion she had given him. Since that day decades ago, he spent his life collecting and cataloging lost things, but he never finds a way to reunite people with their things. When he dies, he leaves his idyllic but haunted house to his assistant, who is charged with returning items to their owners. A charming, romantic ghost-story that will put you in the mood for tea and biscuits!"
