In this episode of Outlook's Secrets and Lies series we're revisiting two astonishing stories from our archive about life undercover.

As a young woman Ieva Lesinska was faced with an agonising choice. To renounce her father as a traitor, or defect to the US and leave behind everything she knew in Latvia. Ieva says it was like she was living in a spy movie, and a film has now been made about her life, it's called: 'My Father, the Spy.'

Anas Aremeyaw Anas is a trained lawyer-turned-investigative reporter in Ghana, and a frequent presenter of the BBC's Africa Eye. In his nearly 20 years working undercover, he's exposed judges taking bribes for a not-guilty verdict; top football officials for fixing matches; sex-trafficking rings; organ-harvesting operations. To do so, he had to disguise himself as a psychiatric patient, as a janitor in a brothel and even as a rock in a barren landscape. His work has led to numerous convictions, but his methods are sometimes dangerous and controversial.
