Set in New York City, the novel follows Detective Michael Bennett as he investigates a series of mysterious murders targeting retired NYPD officers. These officers were once part of a notorious narcotics unit, the Land Sharks, whose controversial and potentially corrupt past is coming back to haunt the city. Combining fast-paced action, complex characters, and a tense atmosphere, Paranoia delves into themes of justice, revenge, and institutional cover-ups. All of this plays out while balancing Bennett’s personal struggles with his large family and the moral dilemmas he faces.

Summary

The story opens with brutal murders of retired NYPD officers who had served in the Land Sharks, a narcotics unit infamous for their aggressive tactics and shadowy operations. These deaths, initially dismissed as accidents or isolated incidents, soon reveal a chilling pattern.

Detective Michael Bennett, dealing with the pressures of a complicated family life—including his pregnant wife Mary Catherine’s high-risk pregnancy—is drawn into the investigation when he attends the funeral of a fellow retired cop. Bennett quickly realizes that these killings are systematic and targeted.

As Bennett digs deeper, aided by his new partner Rob Trilling and NYPD analyst Walter Jackson, the narrative reveals layers of corruption and cover-ups tied to the Land Sharks’ operations years earlier. The officers under attack all share connections to a major drug case involving a powerful kingpin named Richard Deason, whose legacy is still felt in the city.

Bennett uncovers evidence suggesting that the Land Sharks employed unethical methods—planting evidence, coercing witnesses, and using excessive force—actions that were protected and hidden by the NYPD leadership to maintain the department’s public image.

Amid the investigation, the antagonist emerges: Kevin Doyle, a former Green Beret turned assassin. Doyle’s military precision and cold professionalism heighten the danger as he systematically eliminates those he holds responsible for past injustices.

Through glimpses into Doyle’s past, it becomes clear his vendetta is fueled not just by revenge but by a twisted sense of justice for innocent lives destroyed by the Land Sharks’ aggressive tactics.

Bennett’s personal life adds emotional depth to the story. As Mary Catherine copes with her pregnancy, Bennett’s large blended family rallies around her, offering moments of warmth and humor amidst the dark investigation.

Meanwhile, Trilling’s secret life sheltering victims of human trafficking introduces another layer of human drama, highlighting themes of protection and redemption.

Political undertones run throughout the book, with City Council candidate Celeste Cantor quietly supporting Bennett’s work while balancing the risk of scandal that could derail her ambitions. The investigation begins to expose cracks not only within the police force but also in the city’s political fabric, suggesting that many powerful individuals had a stake in keeping the Land Sharks’ legacy buried.

As Bennett and his team piece together clues, they uncover an internal NYPD report suppressed for years, revealing systemic misconduct and the lengths to which the department went to protect its own. The chilling reality is that those who should uphold justice instead concealed corruption, allowing the cycle of violence and mistrust to continue.

The tension escalates as Doyle’s killings become more daring and symbolic, targeting not only former officers but also influential figures connected to the Land Sharks’ protection. Bennett races against time to anticipate Doyle’s moves, setting up surveillance and trying to predict his next victim.

Throughout this cat-and-mouse game, Bennett faces increasing pressure from all sides—the threat to his family, the skepticism of his peers, and the daunting possibility that justice might require confronting uncomfortable truths about the police force he serves.

By the latter parts of the story, Bennett and Trilling have built a solid profile of Doyle, and the investigation narrows. The novel builds toward a confrontation, with Doyle’s motivations laid bare: a desire to force the city to reckon with past wrongs by any means necessary.

Throughout Paranoia, the narrative intertwines high-stakes action with ethical quandaries, exploring how personal loss, institutional loyalty, and the thirst for justice can collide in dangerous ways. The novel skillfully balances a complex mystery with rich character development, portraying Bennett’s struggle to protect his family while pursuing a truth that threatens to destabilize everything he believes in.

The story sets the stage for a tense, emotionally charged resolution that questions the nature of justice and accountability in a flawed system.

Jackson’s character represents the often-unseen backbone of police work—the intelligence and data gathering that drives effective investigations. His discoveries challenge institutional narratives and force other characters, especially Bennett, to confront uncomfortable realities, pushing the plot forward into deeper moral and procedural territory.

Supporting Characters

Consequences of Institutional Corruption and the Moral Ambiguities of Law Enforcement

Paranoia’s story delves deeply into the dark repercussions of systemic corruption within law enforcement agencies, highlighting how institutions designed to protect can become sources of betrayal and moral compromise. 

The Land Sharks unit embodies this corruption—while initially lauded for their effectiveness in battling drugs, their methods reveal a disturbing pattern of unethical behavior, including planting evidence and using excessive force.
