Sergeant at Arms: Inside Book 8 of the Michael Dunn Series

A Madman Tries to Go Straight

Michael Dunn has promised his wife he will stop killing people. In Sergeant at Arms, the eighth book in Philip M. Coston’s Michael Dunn series, we find out exactly how long that promise lasts.

The Enterprise, Dunn’s international theft empire, has a new name: the World Warehouse. It also has a new business plan. Salaried staff, paid benefits, bonuses for high-value “acquisitions,” and a leadership team that no longer gets its own hands dirty. On paper, it looks almost respectable. In practice, it is still run by the most dangerous man in Europe.

If you have followed Dunn from his Air Force days through seven books of heists, betrayals and narrow escapes, this is the installment where his two worlds collide. If you are new to the series, it is a sharp, darkly funny entry point into the mind of a villain who is always sure he is the hero.

The Setting: A Quiet Life in Bern

The book opens with the Dunn family hiding in plain sight in Switzerland. Michael and Leila live as Ezron and Zoe Muller in a renovated farmhouse in one of Bern’s wealthiest neighborhoods. Their daughter Diane handles payroll for the World Warehouse. Their neighbors wave hello, dairy cows graze in the fields Leila lent to the local cooperative, and two little dachshunds rule the house.

Dunn even buys a luxury car dealership as cover, posing as a retired professor turned businessman. It is the perfect disguise. It is also, as readers will quickly learn, the perfect place for trouble to find him.

The question hanging over every chapter is simple: can a man like Michael Dunn ever really retire? Leila calls him her “madman” with real affection. She also knows the answer.

The Plot (No Major Spoilers)

Sergeant at Arms runs on two tracks at once, and the tension between them drives the whole book.

Track one: the biggest heists of Dunn’s career

It starts with a trap. A senior figure inside the Defense Intelligence Agency, known only as “Bob,” dangles a shipment of advanced military ground drones in front of Dunn, hoping to lure him into the open. Dunn sees the setup coming. With help from Marsha, a former target turned reluctant spy, he turns the tables in a Sunday-morning raid on a Pennsylvania Army depot that ends with the hunters becoming the hunted.

From there the ambitions grow. Diane, the family’s brilliant mathematician, becomes fascinated with naval railguns, weapons that fire projectiles with electromagnetic force instead of explosives. What follows is an elaborate scheme involving forged orders, a bribable insider at the Pentagon, a cargo ship bound for Diego Garcia, and Dunn’s old ally Sammy Que. Later, a daring railroad operation in Ohio puts the entire World Warehouse at risk when one small detail goes wrong.

Track two: a war on his own doorstep

Back in Switzerland, Dunn’s “legitimate” life refuses to stay quiet. A petty dispute at the dealership spirals into violence. Then a local crime ring threatens his family at the milking barn, and Dunn discovers that his dealership has been quietly infiltrated by the mob.

Swiss gangsters, a crooked construction outfit, a corrupt airport inspector and, eventually, the Sicilian Mafia all come into play. Dunn does not run from any of it. He plans, he manipulates and he strikes first. By the end, he has reshaped the European underworld to suit himself.

The final chapters leave the door wide open. Questions are being asked in Bern, and back in America the evidence trail is growing. For the first time in a long while, the walls may finally be closing in.

The Themes That Make It More Than a Heist Story

Inside the mind of a psychopath

Coston does something unusual for a crime thriller: he steps back and studies his own villain. Throughout the book, the narrator examines how Dunn thinks. Dunn never blames himself. He turns every crime into a justified act in his own head, and he is, oddly, an optimist. As the book puts it, he practices positive thinking “on the devil’s side of the equation.” The result is a character study as much as a caper.

Can a criminal empire go legit?

The World Warehouse rebrand is played partly for satire. Team-building sessions for thieves, benefits packages for burglars and a payroll department for an outlaw company. But underneath the humor sits a serious question. A business can change its name and its structure. Can it change what it actually is?

Family, loyalty and the cost of love

Leila and Diane are not simply sidekicks. Leila controls the money and refuses to fund anything that puts her daughter in danger. Diane wants to prove herself to her father. Both women show empathy Dunn lacks, quietly supporting people who helped them along the way. Their love for him is real, and so is the risk it carries.

Power, not just money

As the book itself notes, killing is never Dunn’s real goal. It is just the result. What he wants is control, over his business, his family, his rivals and the story everyone else believes. Watching him engineer events so that others take the blame is one of the book’s darkest pleasures.

Satire of the system

Government agencies, bureaucrats, politicians and law enforcement all come under fire. Coston uses dark humor and pointed commentary to suggest that the people chasing Dunn are not always much cleaner than he is. Readers who enjoy their thrillers with an edge of political satire will find plenty here.

Key Players

Readers have asked for help keeping the large cast straight, so this book includes a full character list at the back.
