Den of Iniquity : A J. P. Beaumont Novel

Den of Iniquity follows retired Seattle homicide detective J. P. Beaumont as he navigates a tangled web of personal and professional challenges. When his grandson unexpectedly arrives on his doorstep seeking refuge from a fractured family, Beau’s quiet life in Bellingham, Washington, is upended. At the same time, a decades-old friend asks him to reinvestigate a young man’s alleged fentanyl overdose—a death the victim’s loved ones insist was no accident.

As Beau digs deeper, he uncovers a pattern of similar mysterious deaths, each pointing to a chilling conspiracy. The case grows murkier when it intersects with his family’s struggles, blurring the lines between his duty as a private investigator and his role as a grandfather. Jance masterfully weaves Beau’s signature wit and grit with heart-pounding suspense, exploring themes of loyalty, justice, and the shadows of the opioid crisis.

The novel’s pacing keeps readers hooked, balancing forensic detail with emotional depth. Beau’s partnership with his wife, Mel, adds warmth to the story, even as the investigation leads him to confront a vigilante killer hiding in plain sight. With its layered plot and timely social commentary, Den of Iniquity cements Jance’s reputation as a titan of the genre.

Fans of the series will relish Beau’s return, while newcomers will appreciate the standalone intrigue. The book’s climax delivers a satisfying payoff, though the journey—filled with red herrings and moral dilemmas—proves just as compelling. Jance’s ability to humanize her characters amidst high-stakes suspense makes this a standout addition to the J. P. Beaumont saga.
