Marshall Grade Books in Order

Marshall Grade is the kind of lead who is supposed to disappear and never can. At the start of American Blood, he is a former NYPD undercover officer living under witness protection in New Mexico after an operation went badly wrong. The mob wants him dead, his past is full of unfinished business, and lying low does not come naturally to him.

That is the hook of the whole series. Marshall is told to keep his head down, stay invisible, and let the system protect him. Instead, he keeps stepping into other people's trouble, usually because guilt, curiosity, or a stubborn sense of responsibility will not let him walk away. When a local woman goes missing in American Blood, he starts asking questions, and those questions push him straight back toward dealers, killers, and the people who would love to know where he is.

He is very bad at staying hidden.

The books move across different corners of America, and the setting always matters. American Blood uses the dry, exposed feel of the Southwest, where space should mean safety but never quite does. Marshall's Law pulls Marshall back toward old contacts and old enemies, with California and New York both closing in on him from different directions. In Sometimes at Night, he is back in Brooklyn after a former colleague is murdered right in front of him, and the city becomes a maze of mob players, bent cops, drug money, and family secrets.

Across the series, the ongoing tension is not just the case of the day. It is Marshall's whole damaged history. His undercover work left him with enemies in the criminal world and complicated ties in law enforcement too. The people who know him best do not always trust him, and the people hunting him do not always care who gets hurt on the way to him. That gives the books a constant sense of pressure. Even when Marshall is investigating one missing person or one killing, the larger threat is always close behind.

The tone is lean, fast, and hard-boiled. Marshall is not a polished detective with a neat office and clear rules. He works more like a man improvising his way through danger, using old cop instincts, a willingness to push too far, and a very personal code about who deserves help. He can be cold, funny, reckless, and careful all at once. That contradiction is a big part of why the series works.

If you like crime fiction with a lone operator at the center, the Marshall Grade books deliver that in a stripped-down, no-frills way. The stories are violent, but they are not just about action. They are about what happens when a man who has already lost his old life keeps trying to do one decent thing, and keeps finding out how expensive that can be.
