In November 1809, a British diplomatic envoy named Benjamin Bathurst stepped out of a Prussian inn and walked toward his waiting carriage. He never reached it. The case — set against the backdrop of Napoleonic Europe, secret missions, and a landscape thick with bandits and spies — has remained open for more than two centuries.
