Episode 12 - Missing Prime Minister: The disappearance of Harold Holt.

On the 17th of December 1967, Australian Prime Minister, Harold Holt, was spending a relaxing Sunday at his beach house in Portsea, Victoria. Holt wanted to swim before lunch to ‘work up an appetite’, but when he went into the water, he was quickly swept out of his depth and disappeared beneath the waves. A mammoth search ensued, but no trace of Holt was found. Did he drown in the rough conditions, or was there something more sinister lurking beneath the surface?
