In just a few years, life for Giulia Driscoll has changed drastically. Not only did the former Sister Mary Regina Coelis leave the convent, she is now married, pregnant, and the founding investigator of Driscoll Investigations. Yelp reviewers give them the highest marks in finding lost persons, which explains why Diane Philbey is on their doorstep. Diane’s twin sister Joanne has been missing for three months, with both her employer and the police disregarding it as voluntary. The eminently unlikable Diane refuses to accept this, hiring Driscoll Investigations to locate the woman who was a friend to everyone and liked by all.
