Perfect for you if...

You love crime procedurals with a smart, dogged female investigator who doesn't take shortcuts or trust easy answers.
You want a mystery that weaves multiple cases together and keeps you guessing about who's actually lying.
You're drawn to atmospheric small-town settings where everyone's got secrets and reinvention is always possible.

Maybe not for you if...

You prefer standalone mysteries over series books, since this is book six and carries character history from previous novels.
You want fast-paced action and violence; this is methodical detective work with long stretches of interviewing and digging.
You're looking for a treasure-hunting adventure story rather than a character-driven investigation.

About this book

Private Investigator Cassie Dewell takes on two cases in Montana. A wealthy Florida widow hires her to track down a con man who has disappeared with her fortune. The investigation leads Cassie to Anaconda, a former copper mining town known for reinvention. As she digs deeper, Cassie questions whether her client is being fully truthful. Simultaneously, Cassie works on an unusual assignment involving a poem that promises buried treasure. The poem has sparked a competitive hunt that has resulted in five deaths among treasure-seekers. Her client in this case claims to be the person who hid the gold and wrote the poem, and he has hired Cassie to find him. Balancing both investigations, Cassie navigates Montana's landscape while uncovering darker elements beneath its picturesque surface. The cases present numerous complications and unexpected developments.
