Murders strike on three continents: a geneticist in a Princeton biohazard lab, a Vatican archaeologist in St. Peter’s Basilica, and a U.S. senator’s son near an African Red Cross camp—all victims branded with a Druidic cross burned into their flesh. Commander Gray Pierce races to decode a centuries‑old riddle from a cryptic medieval codex and a mummified corpse in an English peat bog, revealing a Guild conspiracy threatening global collapse via hidden population control secrets. With ex‑lover Vigor Luca and new partner Seichan, Gray pursues leads from Rome’s Coliseum to Norway’s peaks and Celtic tombs, where salvation hinges on the Doomsday Key—an artifact buried by a saint.
