Searching for his missing brother in Prague, an American encounters a world of killers, gangsters, and ancient mysteries in a “satisfyingly twisted tale” (Publishers Weekly). When American collections agent Lee Holloway receives a letter from a mysterious woman named Vera concerning his missing brother Paul, curiosity takes him to Prague in search of answers. But what he finds in the historic city’s looming shadows and cobbled streets is a mind-bending world of conspiracy and danger. A world where black magic and sixteenth-century alchemy aren’t just footnotes in history books. A world where gangsters with fairy-tale names and a bloodthirsty serial killer exist alongside grim reminders of Nazi invasion. And where a priceless watch named The Rudolph Complication—commissioned by an eccentric Roman emperor—is rumored to hold the secret to eternal life. As Lee delves deeper into the question of Paul’s fate, he discovers unsettling truths about his brother . . . and himself. Now Lee must unravel the tangled threads of Paul’s last days if he wants to escape the ancient city alive. Echoing with ghosts and mythic monsters from Europe’s storied past, this is a heart-pumping thrill ride into the very heart of darkness.
