Detective

Elias Cross wanted nothing more than to disappear. Once the city’s most brilliant forensic architect, he vanished after a scandal that destroyed his career. But when an old friend turns up dead — and the body is staged inside one of Elias’s abandoned designs — he’s pulled back into a world he swore he’d left behind. Each crime scene is a building. Each building is a clue. Each clue points to an impossible blueprint for the city’s destruction. With only a reckless journalist and a washed-up detective by his side, Elias must outwit a ghostly mastermind known only as The Mason. But as the city becomes a maze of deadly puzzles, Elias discovers the final design isn’t about buildings. It’s about him.

In Halcyon, every crime hides a code. Adrian Cross, a disgraced cryptanalyst, wanted nothing more than to fade into obscurity. But when a string of murders leaves cryptic puzzles etched into the city’s walls, he’s pulled into a deadly game only he can solve. Partnered with Detective Iris Navarro, Adrian unravels a web of secrets spanning law enforcement, corporate power, and his own past. Each cipher cracked saves a life—but also reveals another victim. As the bodies pile up and the codes point closer to Adrian’s family, he realizes the truth: The city itself is a message. And decoding it may cost him everything. In Halcyon, knowledge isn’t just power—it’s survival.
