A Thin Disguise
by Catherine Bybee
2021
Ex-assassin Olivia has been quietly atoning for years when she takes a bullet meant for FBI agent Leo Grant on the Las Vegas Strip. Waking with no memory and a target on her back, she leans on Leo and the MacBain team while pieces of a dark life resurface.
Series background & context
The Richter novels pick up threads first teased in the First Wives books, revealing that the strict German boarding school Sasha and Jax once attended was far more than an elite finishing academy. Richter trained children in languages, technology, surveillance, and weapons, then quietly rented out their skills to the highest bidder.
In Changing the Rules, Claire Kelly is working for MacBain Security and Solutions when she is assigned to go undercover at a California high school with fellow operative and long time crush Cooper Lockman. Their mission is to uncover who is running a prostitution ring that targets vulnerable students, but the case also forces Claire to confront the way Richter shaped her view of loyalty and home.
A Thin Disguise puts former assassin Olivia front and center. After years of trying to balance the scales by anonymously protecting victims, she takes a bullet meant for FBI agent Leo Grant on the Las Vegas Strip and wakes up with no memory of who she is. As Leo and the MacBain team work to keep her alive, fragments of her past bleed through, and she has to decide whether she deserves a future with the man she has saved.
The third book, An Unexpected Distraction, belongs to Jax Simon, a capable operative who returns to London when her parents abruptly announce a divorce. Digging into their reasons sends her back into Richter’s files and halls, this time with observant financier Andrew Craig at her side. Together they uncover just how deeply the school’s manipulations have shaped lives, including Jax’s own, and what it will take to shut that legacy down.
Richter leans strongly into romantic suspense, with stakeouts, undercover work, and international travel threaded through each love story. Longtime readers will recognize familiar faces from Weekday Brides and First Wives, while new readers can still jump in at Changing the Rules and follow a complete arc about found family, redemption, and choosing who you want to be when someone else tried to write your story for you.
