Hidden Traces, Yesterday, 8pm

The Fuhrer spent a quarter of his time in power there, surrounded by his most faithful lieutenants and his mistress Eva Braun, and it was against this beautiful backdrop that some of the darkest ideas in human history were formed.

Then there’s the mystery surrounding “liftgate”, when footage leaked of Beyonce’s sister Solange seemingly lunging at her brother-in-law, and the scathing lyrics to Beyonce’s album Lemonade. Were they really aimed at her husband, or was it all part of their PR machine?
