Over the past several months, Dan Snow has produced some of the most interesting and intellectually stimulating programmes on the BBC.
The other night, he was exploring these mysterious underground tunnels developed by the Nazis, in occupied Poland.
His history of the railways, was epic, and last weeks programme on the Alaskan gold rush trail, was beautifully produced.
Currently only Chris Tarrants new Remote Railway Journey's series can hold a candle to Mr Snow.
