They were cold, they were tired, and they had just torn down a large stone cairn on a freezing Arctic headland and found it empty. This is where Sir John Franklin’s men should have left a written record of where they had gone next. To find Erebus and Terror, the searchers had first to find a note.
But there was something even worse than finding nothing in the cairn.
It was finding a cylinder in the cairn, frantically opening it, unrolling the note with shaking hands and hammering heart, and finding it was a missive from another Franklin searcher – possibly even from someone on your own expedition.
