Molly Gray’s life is about to change in ways she could never have imagined. As the esteemed Head Maid and Special Events Manager of the Regency Grand Hotel, two good things are just around the corner --- a taping of the hit antiquities TV show Hidden Treasures and even more exciting, her wedding to Juan Manuel. When Molly brings in some old trinkets to be appraised on the show, one item is revealed to be a rare and coveted artifact worth millions. Molly becomes a rags-to-riches sensation and a media frenzy swirls as she prepares to sell her priceless treasure. Then, on auction day, the treasure suddenly vanishes and Molly and her friends find themselves at the center of the boldest art heist in recent memory. But the key to this mystery lies in the past, in a long-forgotten diary written by Molly’s Gran. 

With her flair for cleaning and proper etiquette, Molly Gray has risen through the ranks of the glorious five-star Regency Grand Hotel to become the esteemed Head Maid. But just as her life reaches a pinnacle state of perfection, her world is turned upside down when J. D. Grimthorpe, the world-renowned mystery author, drops dead on the hotel’s tearoom floor. When Detective Stark, Molly’s old foe, investigates the author’s unexpected demise, it becomes clear that this death was murder most foul. Suspects abound, and everyone wants to know: Who killed J. D. Grimthorpe? As the high-profile death threatens the hotel’s pristine reputation, Molly knows that she alone holds the key to unlocking the killer’s identity. But that key is buried deep in her past, as long ago she knew J. D. Grimthorpe.

Molly Gray has always loved the holidays. When Molly was a child, her gran went to great lengths to make the season merry and bright, full of cherished traditions. The first few Christmases without Gran were hard on Molly, but this year, her beloved boyfriend and fellow festive spirit, Juan Manuel, is intent on making the season Molly’s most joyful yet. But when a Secret Santa gift exchange at the Regency Grand Hotel raises questions about who Molly can and cannot trust, she dives headfirst into solving her most consequential --- and personal --- mystery yet. Molly has a bad feeling about things, and she starts to wonder: Has she yet again mistaken a frog for a prince?

Molly Gray is not like everyone else. She struggles with social skills and misreads the intentions of others. Her gran used to interpret the world for her, codifying it into simple rules that Molly could live by. Since Gran died a few months ago, 25-year-old Molly has been navigating life's complexities all by herself. No matter --- she throws herself with gusto into her work as a hotel maid. But her orderly life is upended the day she enters the suite of the infamous and wealthy Charles Black, only to find it in a state of disarray and Mr. Black dead in his bed. Before she knows what's happening, Molly's unusual demeanor has the police targeting her as their lead suspect. She quickly finds herself caught in a web of deception, one she has no idea how to untangle.
