revealed a shape carved into the wall, not Neanderthal art, though it might easily have been mistaken for that, but rather a simple circle, crossed by parallel vertical lines. Just past it, a rickety-looking staircase led up to a closed wooden door, secured with a badly rusted padlock.
    She reached out to what looked like a nub of rock on the adjacent wall and gave it a twist, revealing a modern handprint scanner. She placed her right palm flat against the glass plate. There was a faint flash of light as the scanner verified her identity, and then the entire door—padlock, frame and all—swung away to reveal another, almost completely unknown, section of the cave.
    Gallo entered, careful to keep her right wrist turned up at all times, exposing the mark tattooed there. It was the same mark carved on the nearby wall, the distinctive sigil of the secret society into which she had been initiated, and which her boyfriend, George Pierce, was now the director: the Herculean Society.
     

     
    The handprint reader was the last of a series of measures designed to protect this secret part of the cave from unwanted visitors. The tattoo on her hand was a different sort of defensive mechanism, designed to protect her from what lived inside.
    Long before being ‘discovered’ by its namesake, a British infantry captain in 1907, Gorham’s Cave had been one of more than a score of citadels established by the Society and its enigmatic founder, Alexander Diotrephes. The citadels had served an important role in an era when weeks or even months of travel was required to reach far-flung destinations. In modern military terms, the citadels served as both forward operating bases and supply depots for Society agents carrying out important missions around the globe. But for a brief period starting in 2009, when it had been temporarily abandoned, this cave, the original citadel, had served as the headquarters for all Herculean Society operations. It was not a coincidence that, from ancient times, the strait that separated the Mediterranean Sea from the Atlantic Ocean had been called the Pillars of Hercules.
    Now that high speed air travel had shrunk the world, the citadels served more as repositories for the secrets the Society was obliged to safeguard. It was one such secret that prompted Gallo to pause a few steps beyond the doorway and lift her gaze to the ceiling. The upper reaches of this cavern were cloaked in shadow, but she could hear them, creeping stealthily amidst the hanging stalactites.
    They were called the Forgotten, and once, long ago, they had been human. Now they were…something else.
    In ancient times, Alexander Diotrephes, the man who would someday be remembered as the legendary Hercules, had waged a long war against mankind’s greatest enemy: Death. In the early days of that struggle, he had conducted radical scientific experiments with human tissue, and inadvertently unleashed a plague that had transformed an entire city—men, women and children—into terrifying monstrosities. Imbued with the very immortality he sought, but cursed with a primal thirst for human blood, the wraith-like creatures were the inspiration for nearly every legend of ghouls and vampires.
    The Forgotten were Alexander’s greatest regret, the offspring of his hubris. He labored for centuries, looking for a cure, and in return, the Forgotten served as guardians for the Herculean Society citadels. It was a dangerous alliance. Although Alexander had eventually synthesized a compound to satiate their macabre hunger, the instinct to hunt and consume living victims remained strong. Finding some kind of permanent cure for the Forgotten remained one of the Herculean Society’s secondary missions, but the prospects for a workable solution were not good. The problem had confounded Alexander for more than three thousand years.
    The tattoo on Gallo’s wrist had no special intrinsic power to repel the creatures. But it was the symbol of an ancient agreement,
