Riley Gavin and Frank Palmer Books in Order

Riley Gavin and Frank Palmer sit at the crossroads between journalism and investigation. Riley is an investigative reporter, Frank a former Royal Military Policeman turned private investigator, and together they make a pair who can get into trouble from more than one direction. She asks the questions people hate. He follows the trail when questions stop being enough.

That combination gives the series a strong engine. Riley has reason to chase a story even when everyone around her says leave it alone. Frank knows how to read people, pressure points, and danger. Sometimes they work side by side, sometimes from opposite angles, and sometimes the tension between their jobs is half the point.

The first books are grounded in modern British crime, executed gangsters, missing girls, cultish fronts, old underworld business, but the scale keeps opening out. Cases lead into south London, the south coast, Spain, diplomatic circles, organized crime, British Intelligence, and finally the buried fallout of Algeria and military wrongdoing in No Time for Regrets.

Riley asks anyway.

These are not cozy mysteries. The tone is gritty, fast, and sometimes dark, but Magson keeps the plotting clear and the pages moving. There is a slightly traditional detecting feel underneath the pace, because the books are interested in who knows what, who is hiding what, and how Riley and Frank can prove it before someone gets hurt.

Frank is useful because he is not easily rattled, but Riley is the real spark of the series. Her reporting instincts mean she notices when the official explanation feels staged, and she is stubborn enough to keep going when the safer choice would be to back off. That makes her a natural magnet for danger.

If you like crime thrillers where corruption sits close to ordinary life, where gangsters and officials can be equally untrustworthy, and where the leads have to work through real-world mess rather than puzzle-box clues, this series fits well. At heart, it is about two people trying to get to the truth when truth is exactly what others are spending money and muscle to bury.
