The Agency (Max Tomlinson) Books in Order

The Agency books center on Maggie de la Cruz, a special forensic accounting agent whose job starts with following money and quickly turns into surviving gunfire. In The Cain File and The Darknet File, she is pulled out of analysis and into covert operations, where bad intelligence, political agendas, and shifting alliances can be deadlier than the official enemy.

Maggie is not a swaggering super-spy.

That is part of the appeal. She is smart, stubborn, and good with details, which makes her dangerous in a different way. Tomlinson builds the tension around what Maggie can piece together, who she can trust, and how fast she can adapt when a mission collapses. These books treat money trails, shell companies, and hidden loyalties as real weapons, not background noise.

The first novel, The Cain File, starts in South America with a sting aimed at corrupt oil interests and a payoff gone wrong. From there the series moves through kidnappings, eco-terrorists, covert handlers, and the ugly overlap between government interests and corporate power. The Amazon matters here, not just as scenery, but as a place people are willing to exploit, defend, or die over.

Nothing stays simple for long.

By The Darknet File, the canvas gets even wider. Maggie is dealing with a failed meeting in Paris, a missing defector, suicide bombers, and a terror financing network that reaches across borders. The books keep their feet in espionage, but they never lose sight of the human mess inside the machinery, panic, grief, ambition, and the quiet lies people tell themselves before they betray someone.

The geography gives the series its pulse. Quito, Bogota, the Amazon, Paris, and the shadow routes between official diplomacy and covert war all feel important. Maggie is often moving through places where local politics, American interests, and private money collide, so every trip comes with a new version of the truth. The books are fast, but they are also interested in how power gets laundered and how violence is justified on paper before it happens in real life.

If you like spy fiction with fast movement, political shadows, and a lead who has to think her way through trouble, this series lands in a nice middle ground. It has action, but it also has systems, money, and consequence. Maggie is always working a case, but she is also learning how ugly the larger game can get once she is no longer safely behind a desk.
