RED GRADE: Jenn Herrington 3 — A What Doesn't Kill You Super Series Mystery

For fans of Lisa Scottoline, Karin Slaughter, and Lisa Gardner — the third Jenn Herrington Wyoming Mystery, where the most dangerous arena in Wyoming turns out to be the polo field.

Jennifer Herrington has been asked to quietly advise on a murder case. She agreed because she's experienced, trustworthy, and not technically a suspect. That last part doesn't last long.

When polo star Victor Carvalho collapses mid-match and is trampled to death at the Red Grade Ranch, everyone sees a tragic accident. Then his blood work comes back positive for sedatives, and the case turns into something else entirely — a murder with roots in underground betting, organized crime, decades-old polo rivalries, and a web of betrayals that Victor apparently spent years carefully constructing.

Jennifer is quietly consulting for the county attorney when her husband Aaron gets arrested for the murder. The suspected weapon: veterinary sedatives stolen from his own clinic. The conflict of interest: immediate and total. Jennifer can't represent him. What she can do is investigate — without a client, without authority, and with a county attorney who seems more interested in winning than in finding the truth.

The polo world is a small one, and everyone in it has something to hide. A team owner with mob connections. A rival with a grudge going back to prep school. A wife who knew too much and a stable hand who knew even more. And Casey — Aaron's newly discovered daughter — who may be more entangled in this mess than Jennifer is willing to consider while her marriage is already hanging by a thread.

Red Grade is layered, and unsparing. It moves like a polo match: fast-moving, physical, and liable to turn on you when you least expect it.

She thought she was advising from the sidelines. Then they arrested her husband.

The Jenn Herrington Series is Part 4 in Hutchins' What Doesn't Kill You Super Series.
