Egyptologist Daniel Knox's lifelong fascination with Alexander the Great and his tomb could be the death of him. After construction workers excavating in Alexandria expose a catacomb dating back to ancient times, Knox eagerly sneaks in to scout the cavernous and dusty site. Among the relics he finds clues that may solve one of the world's greatest mysteries: the last resting place of Alexander the Great. But Knox is not the only seeker; others are after the prize, and they would kill to win it.
