Once upon a time, some British hard men decided to steal some gold. They went out to an airport, worked their way into a bullion room, and lifted the gold. It was a classic heist for the ages. Here's the thing: they took a taxi home. The black cab was a cool ride, but it also left a witness in the form of the driver, a man chock full of "The Knowledge" and then some. The driver became the key to this case, but also somehow the lock. Figure that one out.
