Step into Sainte-Marée, a wind-lashed coastal town in occupied France where coded lanterns blink from cliff stations and couriers melt into alleys of salt and shadow. Shadows on the Tide gathers 51 all-new logic-grid puzzles—19 Medium and 32 Expert—each with a unique solution and a taut, standalone vignette of resistance, sabotage, and spycraft.

Match people to insertion routes, safehouses, signals, times, covers, cargoes, and targets as you unravel midnight infiltrations, market-stall dead drops, factory alibis, and harbor relays. Every case provides clean blank grids, completed solution grids, and a concise written answer—no trivia, no guesswork, just crisp, fair deductions that reward careful elimination.

Designed for solvers who crave challenge and atmosphere, this collection balances historical flavor with puzzle purity. Whether you crack a single mission over coffee or map a full operation on a stormy night, Sainte-Marée will keep you listening for tin-whistle countersigns long after the last page.

Perfect for fans of rigorous logic puzzles, escape-room thinkers, and historical intrigue. Sharpen your pencil, steady your nerves, and join the network.
