Rob Soliz and Frank Pierce Mystery Books in Order

The Rob Soliz and Frank Pierce books are Dallas police mysteries with a harder, rougher edge. Rob Soliz and Frank Pierce are senior detectives in the Dallas Police Department's Criminal Intelligence Unit, and the series follows them through cases that begin with a disappearance or a killing and then widen into something far more unsettling. Larry Enmon writes from inside the machinery of an investigation, so the books care about interviews, timing, bad luck, and pressure from above as much as they care about twists.

Rob and Frank work because they are not built the same way. Rob is the steadier presence, the partner who helps hold the case together. Frank is more restless, more likely to chase a hunch, and more likely to carry the job home with him. They do not always see a case the same way, and that quiet friction gives the books their rhythm. One grounds the story. The other keeps pushing it into riskier territory.

Dallas matters here.

The city is not just backdrop. In The Burial Place, political pressure crashes in when the mayor's daughter disappears and the best clue points toward the strange word Wormwood and a cult-like trail leading into rural East Texas. In City of Fear, the killing of drug kingpin Ricardo Salazar raises the threat of gang war, while a missing red-haired woman and whispers of voodoo keep the case tilted slightly off balance. By Murder So Foul, the series moves into the August heat and the Great Trinity Forest, where a savage crime scene turns the investigation personal.

What links these books is not one giant master plot. It is the partnership, the job, and the way each case tests how much Rob and Frank can carry. Enmon likes bureaucratic friction, media attention, nervous city leadership, and the constant sense that more people could get hurt if the detectives fall behind. Even when the crimes get darker, the stakes stay human.

The tone sits somewhere between police procedural, crime thriller, and urban mystery. There is action, but the stories do not skip the slower work of chasing half-useful leads, talking to witnesses, and trying to read the people who are lying. The books are interested in how cops think when the obvious answer does not quite fit. There is also a strong Texas feel throughout, from Dallas streets to the woods of East Texas, which keeps the series rooted in place.

If you want veteran detectives, uneasy atmosphere, and cases that keep one foot in reality even when rumor and fear start crowding the edges, this is what Enmon is doing here. Start with The Burial Place for the clearest introduction to Rob and Frank, then read forward to watch the partnership deepen and the cases get meaner.
