It's been four decades since the women of Sigma Delta Tau were last together. The years have been kind to some but not to others. Still this is supposed to be a pleasant diversion for former sorority member and current private investigator Aubrey Merritt. She's come to New Mexico to reconnect with old friends, and she's brought her personal assistant Olivia Blunt along with her to help with her bags. But when one of the sorority sisters is murdered, all eyes turn to the World's Greatest Detective to solve the case. It's going to take both Aubrey and Olivia to cut through the knot of old hurts and current grievances to find the killer.
