Cornwall, 1895. Fishermen are vanishing from the windswept village of Porthreath. Sailors whisper of a ghost ship gliding beneath the waves-a dark leviathan with glowing eyes that surfaces only in fog. When Sherlock Holmes receives a cryptic summons from the reclusive "Mr. Edward Smith," he expects another case of superstition masquerading as mystery. What he discovers is far more extraordinary. The mysterious Mr. Smith is none other than Captain Nemo-the legendary commander of the submarine Nautilus, scourge of empires, and the most wanted man in the British dominions. Born Prince Dakkar of Bundelkhand, he watched the British East India Company murder his wife, his son, and his entire dynasty. or forty years, he waged a one-man war against colonialism from beneath the waves. Now, aged but unbroken, he lives in hiding-haunted by visions of an ancient civilization and hunted by enemies who will stop at nothing to claim the secrets he guards. When a stolen artifact threatens to unleash forces that destroyed a world twelve thousand years ago, Nemo must turn to the one man brilliant enough to help him: Sherlock Holmes. Together with the loyal Dr. Watson, they will descend into the Temple of the Depths-the drowned ruins of a civilization that makes Atlantis seem young. They will encounter the Guardians-beings who have watched over forbidden knowledge since before the pyramids rose. They will face Captain Abraham Farragut, a man whose hatred has festered for thirty years into murderous obsession. And in the darkness beneath the sea, Captain Nemo will confront the choice that has defined his existence: vengeance or redemption, hatred or forgiveness, the shadows of the past or the light of a future worth living.
