Marty Nickerson Books in Order

The Marty Nickerson novels are legal mysteries set mainly on Cape Cod, Massachusetts. Their lead is Martha "Marty" Nickerson, a smart, stubborn lawyer who starts out as a Barnstable County prosecutor and later moves to criminal defense. The series follows her through four cases where a quick answer is rarely the whole answer.

Marty cares about victims and believes the justice system should work. That belief is tested early in Absolute Certainty, when a new murder makes her question whether a man she helped convict might actually be innocent. Her need to follow the evidence puts her at odds with her own office, especially when institutional pride and political ambition make reopening a case inconvenient.

The series is as interested in the work of law as it is in the mystery. Marty has to assess evidence, challenge assumptions, prepare for trial, and make difficult choices about clients and colleagues. Connors uses the details of hearings, investigations, and courtroom strategy to create tension, but the books stay focused on people rather than legal jargon for its own sake.

Harry Madigan is central to Marty's life and work. He is a defense attorney, Marty's law partner, and her romantic partner, which means their professional cases can also carry personal baggage. Their office later includes the young lawyer Kevin Kydd, while Marty's former coworkers remain part of the professional world she cannot quite leave behind.

Each book brings a new criminal case. Temporary Sanity puts Marty and Harry on the defense side of a terrible, publicly witnessed shooting while another troubled woman arrives at their office seeking help. In Maximum Security, Marty represents Harry's former girlfriend after the woman's husband dies. False Testimony gives Marty and Harry two demanding cases, both involving clients whose explanations are hard to trust.

Cape Cod gives the series its own shape. The coastline, wealthy summer residents, local politics, and tight social circles all matter when a crime occurs. Marty is often dealing with people who know one another, remember old grievances, and have plenty to lose if the truth comes out.

These are steady, character-driven legal thrillers with courtroom pressure, moral gray areas, and a relationship at the center. Start with Absolute Certainty for Marty's full arc, then read in publication order to see how her career, partnership, and view of justice change from case to case.
