| Summary | In the shadowy intrigue of wartime Lisbon—a neutral haven where Axis and Allied agents mingle openly—a daring Japanese secret agent, Shiraki Hyouji, and his reluctant companion embark on a mission shrouded in urgency. Tasked with safeguarding Japan’s honor, they venture to Zerzei Island, a verdant paradise concealing the ruins of Marquis Mentore’s fortress. Rumors swirl of a cryptic cipher key hidden within, vital to Britain’s last-ditch survival plans. \nShiraki’s charm disarms the island’s spirited locals, unearthing whispers of the Marquis’s obsession with a mysterious tuning fork and his vanished presence. As German operatives and British pirates close in, the duo infiltrates the fortress, racing against time to decode clues entwined with music and science. A gramophone’s haunting melodies and a high-pitched metallic resonance hold the key—but danger erupts in gunfire and betrayal. \nWith Shiraki’s unflappable cunning and a nerve-wracking escape plan, they edge toward a revelation that could alter the war’s tide. Yet even victory leaves questions: What secrets linger in the Marquis’s silence? And whose side do the island’s beguiling inhabitants truly favor? |
