Perfect for you if...

You enjoy mysteries with a personal stakes angle—the protagonist's family ties complicate the case in ways pure detectives can't handle.
You like fast-paced crime stories that don't require 500 pages to deliver tension and a solid payoff.
You appreciate private investigator procedurals with a fresh voice, especially when the lead character is someone learning the job as they go.

Maybe not for you if...

You need elaborate world-building or character development—this is lean and efficient, not introspective.
You prefer cosy mysteries with low stakes and charming side characters rather than genuine danger.
You want standalone books; if you like this, you'll want more of the J.D. Pierson Case Files, so avoid if series commitment isn't your thing.

About this book

Jenny receives an unexpected call from the state penitentiary. Her uncle, imprisoned years ago for robbery, asks her father—a private investigator—to help his daughter, Betty, out of trouble. Jenny notices a pendant around Betty's neck and suspects it may be stolen, but Betty refuses to discuss its origin. When Betty is shot and killed on her way home, the necklace vanishes. Jenny realizes the case involves not just theft, but murder. She must identify a man named Jack and track him down before he kills again and escapes.
