You step out of West Mersea Library and the air tastes of salt and seaweed; gulls wheel above the harbour as the puzzle app prompts your first clue. The route threads through a compact town, past a harbourside pub and the Dabchicks Sailing Club, then skirts chalky foreshore and low salt marsh where the tide keeps time with your progress.
