May 1914. Richard Hannay, bored in London after years in southern Africa, lets a frightened American into his flat — and a few days later finds him dead on the floor with a knife through his heart. Wanted for murder and hunted by a German spy ring, Hannay has three weeks to survive until he can warn the government. He runs for the moors of Galloway, then back south to a meeting of ministers and a Kent clifftop.
This is John Buchan's 1915 novel, not Hitchcock's very different film. London, St Pancras, Cairnsmore of Fleet and Moffat are named in the book; Hannay's hiding places on the moors and the Kent resort of Bradgate are not real, but the steps that gave the book its title are.
Ernest Shackleton set out in 1914 to cross Antarctica on foot. He never even landed. His ship, Endurance, was trapped in the pack ice of the Weddell Sea, drifted for ten months and was crushed and sunk, leaving 28 men on the ice with three lifeboats. What followed — months on drifting floes, a landing on Elephant Island, an 800-mile voyage in an open boat and a march across the mountains of South Georgia — ended with every one of them coming home alive.
The route follows that escape from South Georgia to the wreck and back, with dates from Shackleton's own account, South. Most of these places can only be reached by expedition ship.
