Blood Stain. The Magnolia Series, #3

Karina and LiAnn settle into their new lives, each enjoying their roles as co-owners of The Magnolia House and as newlyweds to the men of their dreams, all while spending quality time with their elderly family members. The worries about the mob are over, and fears about testifying against the devilish owner of Jubilee Retirement Corporation are a fleeting memory, so they concentrate on making the lives of their elderly charges as fulfilling and satisfying as possible, guarding the secrets of some of the residents as if their own.
Unfortunately, sins of the past won't remain buried, and when they resurface, reputations aren't the only things in danger. When a new resident moves in with secrets of his own, he brings along well-kept mysteries of the sordid past of Hot Springs, dating back centuries, but that isn't their only problem. Someone from their past is determined to bring misery into their lives. LiAnn and Karina find themselves embroiled in a myriad of tragedies, including murder.
