In Episode 6 of The Sixth Bureau, a series from The Big Take, with spy Xu Yanjun in prison, the US government pursues some of his collaborators. Plus, host Jordan Robertson gets an unexpected call which leads to a big discovery.

The Sixth Bureau from Bloomberg News follows an MSS intelligence officer whose mission was to acquire the crown jewels of American aerospace companies. With aliases, blackmail and the occasional break-in, he targeted corporate giants. That is, until his sloppiness — and a cunning FBI sting — led to a stunning reversal: Xu Yanjun became the first Chinese intelligence officer ever convicted on American soil.

The Sixth Bureau is the story of superpowers, their secrets and how one Chinese spy got caught. Listen to Episodes 1 - 5 here.
