When the World's Greatest Detective reunites with her college friends, she discovers that time doesn't heal all wounds.

It's been four decades since the women of Sigma Delta Tau were last together. The passing years, growing families, and maturing careers may have strained the bonds of sisterhood, but now a reunion at the Western ranch of one member offers an opportunity to renew acquaintances...and at least one long-standing grudge.

Still, this weekend 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 along her personal assistant, Olivia Blunt--an aspiring detective who is learning more about packing bags on this trip than about solving crimes.

The shocking murder of a sorority sister changes everything. With the local police overmatched, all eyes turn to Merritt and Blunt to crack the case. With a surprising abundance of suspects, it's going to take both of them to cut through the knot of old hurts and current grievances to find the killer.
