Recommended Reading Order: Where to Begin?
If you are new to the novels of Brian Thiem, you have two excellent entry points depending on the style of mystery you prefer. As a retired Oakland Police Department homicide detective and U.S. Army veteran, Thiem writes with an authenticity that few authors can match. His books are split into two distinct mystery series: the gritty, street-level Detective Matt Sinclair Series set in Oakland, and the coastal, team-based Mudflats Murder Club Mysteries set in South Carolina.
For readers who enjoy raw, intense, and atmospheric urban police procedurals, the best place to start is the debut novel, Red Line. If you prefer mysteries centered around cold cases, retired investigators, and a coastal island community, you should begin with The Mudflats Murder Club. Regardless of which series you choose, you should read the books in order of publication to fully appreciate the character arcs and evolving relationships.
The Detective Matt Sinclair Series: Gritty Oakland Procedurals
This series is deeply grounded in Oakland, California, drawing directly on Thiem’s 25 years of experience patrolling the streets, leading vice narcotics operations, and directing homicide investigations. The books follow Detective Matt Sinclair, a relentless investigator who must navigate the complex bureaucracy of the police department, his own personal demons, and the gritty realities of violent crime in the East Bay.
To follow Matt Sinclair's personal and professional journey, read this trilogy in chronological publication order:
1. Red Line (2015)
In Thiem's debut novel, readers are introduced to Oakland Homicide Detective Matt Sinclair. Still recovering from a past shootout that left his partner dead, Sinclair is assigned to a high-profile homicide investigation that soon hits dangerously close to home. When a transit worker is found murdered, followed by a series of related killings, Sinclair discovers the victim was someone he once failed to protect. As the case unravels, Sinclair must confront his own guilt and a killer who is targeting people linked to his past. The book is highly praised for its realistic depiction of police work, from the tedious gathering of evidence to the psychological toll of the job.
2. Thrill Kill (2016)
The second installment in the series escalates the tension. Detective Sinclair is called to investigate the murder of a former runaway whose body is found in a theater in Oakland's revitalized downtown district. The victim's death initially appears to be a random act of violence, but Sinclair’s investigation reveals a far more sinister plot. As he digs deeper, he finds himself navigating the dark underbelly of Oakland's nightlife and uncovering a conspiracy that involves influential city figures and internal police corruption. Sinclair must decide how far he is willing to go to obtain justice when the path leads to the highest levels of power.
3. Shallow Grave (2017)
The trilogy concludes with Sinclair’s most personal investigation yet. When a retired Oakland homicide inspector—who also served as Sinclair's mentor and surrogate father—is found dead, the official ruling is suicide. Sinclair refuses to believe it and launches an off-the-books investigation. His pursuit of the truth takes him from the streets of Oakland to the surrounding suburbs, where he uncovers secrets that his mentor was desperately trying to keep buried. Shallow Grave combines the intricate procedural steps of a classic detective novel with a moving exploration of loyalty, grief, and the legacy of a career in law enforcement.
The Mudflats Murder Club Mysteries: Coastal Cold Cases
Shifting focus from the West Coast to the South Coast, this series reflects Thiem's own retirement move to Hilton Head, South Carolina, where he volunteers with the local sheriff’s Cold Case Team. The series is set on the fictional Spartina Island and follows a dedicated group of retired law enforcement officers, forensic specialists, and intelligence analysts who form a "cold case club." Together with active-duty Detective Sergeant Charlotte “Charlie” Nash, they tackle cases that have stumped local authorities.
The recommended reading order for the Mudflats Murder Club series is:
1. The Mudflats Murder Club (2025)
The series kicks off when a body washes ashore on the marshy mudflats of Spartina Island. Seeking to assist local law enforcement, retired detective Sean Tanner helps establish a volunteer cold case team. Composed of retired experts with decades of combined experience, the group works alongside Detective Sergeant Charlotte "Charlie" Nash. As they piece together the victim’s identity and final hours, they uncover deep-seated island secrets and prove that retirement has not dulled their investigative instincts.
2. A Killer in the Cordgrass (2026)
The second book finds the tranquil, tight-knit retirement community of Spartina Island shattered when the body of Courtney Evanson is discovered hidden in the coastal dunes. The Mudflats Murder Club is called in to assist with the investigation. Tanner, Nash, and the rest of the club must navigate a maze of local gossip, hidden motives, and historical grudges to find a killer hiding in plain sight before they strike again.
3. A Death in the Deluge (2026)
In this high-stakes installment, the team faces both a human threat and a natural disaster. A serial predator is active on the island, leaving a single .22 bullet as a calling card at every crime scene. When a local teenager goes missing, Tanner and Nash launch a desperate, off-the-books investigation. With a Category 3 hurricane rapidly bearing down on the Carolina coast, the team races against time to locate the teen and identify the predator before the impending storm washes away all remaining physical evidence.
4. A Killing Reputation (Forthcoming, January 2027)
The fourth entry in the series centers around a murder at a prestigious charity gala on Spartina Island. The investigation reveals that the victim’s death is tied to cold secrets dating back forty years. The Mudflats Murder Club must delve into the history of the island's elite to connect the past and the present, demonstrating how long-buried grudges can eventually turn deadly.
What to Know Before You Start: The Inside Details
Understanding the background of Brian Thiem's novels helps readers appreciate the depth of his writing:
- Unmatched Realism: Unlike many crime thrillers that feature heroic, superhuman detectives who break the rules without consequence, Thiem’s books depict the realistic daily grind of police work. Readers get an insider's look at how police databases are used, how investigations are structured, and how the chain of command operates.
- The Setting as a Character: The setting is vital in both series. Oakland's diverse neighborhoods, local politics, and economic struggles shape the Matt Sinclair books, while the tidal creeks, cordgrass marshes, and retirement culture of South Carolina define the atmosphere of the Mudflats Murder Club.
- Character Continuity: Although the individual cases in each novel are self-contained and resolved by the final page, the characters' personal lives, mental health struggles, and professional relationships develop continuously. It is best to read each series in order to experience this growth naturally.
