Shadows on the Tide plunges you into Muros de la Costa, a mist-shrouded fishing village on Spain’s Atlantic shore, where the creak of wooden piers and the salt-laden air conceal a network of horrors. Seven-year-old Ioana Popescu vanishes on a routine errand for bread, and two disparate souls race against time to unearth the truth buried beneath decades of silence.
Marcos Varela, a former Guardia Civil detective haunted by a case that derailed his career, returns to the coast determined to atone for past failures. Alongside him is Clara Díaz, an intrepid local journalist desperate to illuminate the untold stories of her community. Their investigation is sparked by subtle clues—a single boot print with a diamond-grid sole, an anchor-shaped button, a stray seagull feather—and guided by the whispered counsel of Fermín, a retired fisherman who knows every hidden passage in the abandoned cannery.
