Another great documentary shown as part of the BBC STORYVILLE series. This one's a feature-length exploration of the Silk Road, a notorious dark web Ebay site for illegal drugs, and in particular the manhunt for the mystery figure behind it. The format plays out like a thriller, starting off interesting and educational and building momentum until it becomes gripping, twisting and surprising you at every turn. It reminded me of the Netflix doc DON'T F**K WITH CATS, but better, without the endless irrelevant talking head footage from Internet nerds.
