Cathy Marsden Thriller Books in Order

The Cathy Marsden thrillers are set in wartime Leeds, where the danger of the Second World War reaches far beyond the front line. Cathy is a police sergeant seconded to the Special Investigation Branch. Her work begins with deserters and crimes on the home front, but the series quickly pulls her into espionage, sabotage, black-market dealing, and murder.

Cathy is capable, direct, and used to being underestimated. She works in a profession dominated by men, during a war that has changed what women can do while leaving many old attitudes firmly in place. Her determination is not presented as easy heroism. She has to earn trust, take risks, and deal with people who assume her gender makes her less suited to serious police work.

War makes every case more dangerous.

The first novel, No Precious Truth, takes place in 1941. Cathy's civil-servant brother Dan arrives from London carrying a secret connected to a special counter-espionage unit. A German agent has escaped and is heading for Leeds to attack targets important to the war effort. Cathy must learn to navigate a world of double agents, coded information, and divided loyalties while the city lives with rationing, fear, and the threat of air raids.

In The Faces of the Dead, the action moves to 1944 as the Allies prepare for D-Day. A local gangster dies in a car crash, but weapons stolen from a United States military base are found in his vehicle. The apparent accident sets off gang conflict and a chain of disappearances, leaving Cathy to work out who is directing the violence. Her personal hopes and relationships are also tested by the demands of the case.

Leeds is again a central part of the story. These books show a city under strain, with soldiers nearby, goods in short supply, families separated, and criminal opportunities growing in the gaps. The historical setting adds tension, but the investigations stay focused on people: who is frightened, who is being exploited, and who has been overlooked.

The tone is high-stakes historical thriller rather than a cosy wartime mystery. Cathy has help from her colleagues and family, but she is the one who has to keep pushing when the case becomes politically sensitive or personally risky. Start with No Precious Truth to meet her and see the wartime world that shapes both books.
