Mandy Wiener is one of the country’s best known and most credible journalists and authors; she’s worked as a multi award-winning reporter with EWN; appeared on all sorts of radio stations and she’s been crowned as The CNN African Radio Journalist of the Year.

Mandy Wiener has also earned a reputation for her work exposing South Africa’s deepest darkest Underworld.

This incredible South African specialises in investigative reporting and legal matters, having extensively covered both the corruption trial of former national police commissioner Jackie Selebi and the infamous Brett Kebble murder trial.

Mandy Wiener's new book, The Whistle Blowers, shines a light on the plight of this special class of justice-seeker, advocating for changes in legislation, organisational support and social attitudes in order to embolden more potential whistle blowers to find the courage to step up.

And she's joined the Good Things Guy Brent Lindeque (again) to figure out how all of this could possibly be a good thing.
