Synopsis

She wouldn’t deserve to be called The Grandmaster of Theft if she couldn’t steal The Maker’s Tear…
Part crime solver, part crime causer, the cunning heiress Cassidy Cain pursues her own brand of noblesse oblige as The Grandmaster of Theft, a lady thief who uses her privilege and wits for those without her advantages.
Under normal circumstances, she chooses her marks. This time, the target – the obnoxious celebrity Narcissa Richmond – challenges her to steal a religious relic while aboard a train. Nevertheless, Cassidy sees this as an opportunity for her most spectacular caper yet.
As Cassidy delves deeper into the job, she uncovers a conspiracy centered around her capture. With criminals and investigators alike targeting her, she must stay one step ahead of them all or else lose the relic, her reputation, and her life.

To give a head up for those who aren't interested in this stuff (and for those who are), this story features a Girl's Love subplot. Also, while there isn't anything explicit with sexual content (i.e. no on-screen sex scenes), the series does lean more towards "mature" in acknowledging it exists and happens.
