Ten master thieves walked into an impenetrable vault. Nine of them never walked out.
The Acheron Array is a subterranean fortress buried deep in the Swiss Alps. Built by a billionaire defense contractor, it is guarded by Argus, a flawless autonomous artificial intelligence. To prove their system is truly unbeatable before a massive government sale, the corporation offers fifty million dollars to any thief who can survive twelve hours undetected inside.
When the blast doors open at sunrise, the proctors expect to find ten defeated trespassers. Instead, they find a massacre.
Nine of the world's greatest infiltrators lie dead inside the facility's walls, vents, and subfloors. There is not a single mark on their bodies. Only one participant survived: an arrogant hacker who spent the entire night sitting in plain sight.
Inspector Frank Dawson thinks he has an open and shut case. He arrests the survivor for orchestrating a remote suffocation. But corporate legal liaison Justin Jean knows a coverup when he sees one, and he calls in the only man capable of dismantling a perfect system.
Saul Sheldon does not care about police theories, and he certainly does not care about human motives. He cares about thermodynamics.
While the police search for a killer, Saul examines the architecture. He measures airflow, traces cooling systems, and calculates the exact thermal footprint of a terrified human being. He quickly realizes the Acheron Array is not just a building. It is a highly sensitive thermal engine. The AI was never programmed to hunt humans, but its cold, mechanical logic might be far more dangerous than any human murderer.
With the innocent survivor minutes away from federal prison and the corporation moving to bury the truth forever, Saul must construct a lethal demonstration to prove the impossible. He has to show the world that the building itself is the killer.
Saul Sheldon and the Interpretation of Fire is a claustrophobic, locked-room thriller where the deadliest weapon is the air you breathe. Perfect for readers who love brilliant detectives, impossible crimes, and relentless suspense.
