Air date: Jan 19, 2014

On a rocky outcrop in central Germany stands the forbidding ruins of a monstrous castle where a scientist conducted a series of sinister experiments. Hidden within one of England's most famous country manors is the story of long-buried Egyptian treasure. And half a mile from the coast of France is the tiny island of Sainte-Marguerite, home to the forbidding Fort Royal, where a mysterious masked prisoner was locked up for decades.
