Dangerous Mercy — Kathy Herman

When elderly Adele Woodmore moves to Les Barbes to be near the Broussards, she wants nothing more than a comfortable, quiet life. Employing men from Father Vince's halfway house for the homeless to do odd jobs, she takes an interest in their lives and is delighted to be helping them get back on their feet.

Now a series of murders has cast a pall over the town and one of Adele's handymen becomes a person of interest to the police. But Adele continues to show the young men kindness and care, in spite of her friends' concern. This time that kindness could kill her.
