4. A detective calls

A police chief in Brazil investigates Fox. He spends months overseeing surveillance of Fox’s yacht, then months more investigating how more than a tonne of cocaine ended up on board.

For Andre Gonçalves, it begins with a tipoff from Britain’s National Crime Agency. He’s determined to fix what he sees as a grave injustice for the sailors after their arrest and harsh sentencing.
