Bennington P.I. Books in Order

The Bennington P.I. series follows Frank Bennington, a longtime Washington, D.C., political insider who has become a private investigator. Frank is older, tired, skeptical, and fully aware that the capital runs on ego, secrets, and backroom deals. He still knows the city well enough to find the people who do not want to be found.

The series begins with The Second Oldest Profession. A young political newcomer, Colin O'Shea, finds himself trying to protect a woman targeted by a powerful congressman with presidential ambitions. The story introduces the world Frank knows best, where personal desire and public power can become dangerously tangled.

Bonita and Take Two and Call Me in The Morgue bring Frank further into cases shaped by powerful people, corporate interests, and the darker side of Washington influence. In the latter, he races to help a friend while following a trail connected to the business of cancer treatment and the people who profit from it. The mysteries are rooted in noir-style distrust, with clues hidden behind status, money, and official language.

Washington is Frank's home turf.

Frank is not presented as a polished, rule-bound private eye. He is stubborn, blunt, and willing to spend time in the city's bars, private clubs, apartments, and political corridors to get answers. His voice gives the series much of its appeal. He understands that the people who appear respectable in daylight may be the most dangerous ones after dark.

The series changes direction in Illuminati. Political conspiracy remains part of the story, but it opens into a supernatural conflict involving the covert T3 Group, Stasia Wellington, and a struggle between forces of light and darkness. That shift connects the Bennington books more closely to Ulsterman's larger Mac Walker world, while keeping Frank's hardboiled outlook at the center.

Start with The Second Oldest Profession. It introduces the Washington setting, Frank's orbit, and the themes of power, corruption, and personal loyalty that carry through the later books. Bonita and Take Two and Call Me in The Morgue are the next stops before the more paranormal turn of Illuminati.

Bennington P.I. is a mix of political thriller, detective fiction, romance, and later supernatural suspense. It is best for readers who enjoy a cynical investigator, morally compromised institutions, and cases where the official story is usually the least believable version.
