Sworn to protect a scenic island meant to be far from the evils of the mainland, Detective Sergeant Stilwell can feel danger closing in.

Detective Sergeant Stilwell knows that his posting on Catalina Island is no paradise, but to most residents, it seems blissfully separated—by twenty-two miles of ocean—from the troubles of Los Angeles County. But now a threat is coming to his safe haven.

Acting on a tip from a confidential informant, Stilwell and his deputies watch a plane land in the middle of the night at the Airport in the Sky, a remote airstrip in the mountains. A duffel bag of drugs is dropped and the deputies move in, but things quickly go sideways. While Stilwell chases the fleeing pickup man into the mountainside brush, shots are fired on the runway and the plane flies off.

An internal inquiry follows, putting Stilwell on the bench until he is cleared of responsibility for the disastrous operation. But he is determined to find out who brought deadly violence to his island, and begins his own secret investigation into the drug deal gone wrong.

While under orders to remain in the sheriff’s substation, he finds in the lost and found a valuable backpack that was never claimed. He traces it to a woman who disappeared while hiking on the island four years ago. But then why was the pack only turned in two months back? Now thoroughly intrigued, he follows the mystery all the way to the LAPD’s Open-Unsolved Unit and Detective Renée Ballard.

Stilwell and Ballard work the case from both sides of the channel, and soon realize they are on the trail of a criminal who revels in taunting the authorities. Meanwhile, frustrated at being shut out of an investigation on his own island, Stilwell risks his already shaky standing in the department to pursue a case whose reach is wider than he ever imagined.

Page-turning, packed with intrigue, and bringing together an unstoppable investigative team, Ironwood continues the Catalina series with all of Michael Connelly’s signature “relentless narrative drive…evocative atmosphere, realistic dialogue, and well-developed characters” (Washington Review of Books).

The series

Full series details →

Set against the sun-drenched yet shadowed shores of Catalina Island, this series navigates a world where paradise and peril sit side by side.

Here, the calm of the ocean contrasts with the tense, unrelenting investigations that drive each story, giving readers a setting that feels alive and unpredictable.

Read full series description

At the heart of the narrative is Detective Sergeant Stilwell, a seasoned investigator whose posting to the island was meant to be quiet, if not exile. But quiet quickly proves elusive when bodies surface, suspicious disappearances resurface, and the layers of the island’s social and political hierarchies come into play. Stilwell’s pursuit of justice is not just a procedural grind, it’s an exploration of morality, loyalty, and the weight of choices made in a place where everyone knows everyone, yet nobody truly sees the full story.

The series stands out for how it intertwines atmospheric world-building with meticulous police work. From the secluded bays to the island’s elite enclaves, each locale shapes the tension and stakes, while Stilwell’s investigations reveal the complex human dynamics that define life on Catalina. Readers are drawn into a narrative that balances pulse-quickening suspense with reflective character moments, where the unfolding mysteries illuminate not just crime, but the fragility and resilience of those who live among it.

Blending coastal noir, procedural intricacy, and character-driven suspense, the Catalina series captures the quiet menace behind sunny vistas. It’s a world where the beauty of the environment is matched by the depth of the secrets it conceals, leaving readers questioning who can be trusted and how far one will go when the truth comes to light.

What Risingshadow readers think about this book

7/10

I really love Michael Connelly books but I don’t like the Stilwell books as much. It is not the character, I like Stilwell.  This novel had two parallel cases which keeps you interested.  The chapters were short and  jumped back and forth between cases but I thought it flowed well.  I recommend reading, it will hold your interest throughout but I didn’t really like the way either case ended due to lack of details and downgraded my rating.
