Sex, Lies & Surveillance

Damien Delzoppo of Avenue Investigations says he was playing a clean game — "well within the limits of the law" — during an episode that ended with one Melbourne contractor blackmailing a rival into pulling out of the tendering for a local council job.

It seems that the rival — owner of a construction business, 20 to 30 workers — had been winning council jobs left and right. He was significantly undercutting everybody else. It was a mystery.

It didn't take long to find out the guy was having an affair with his materials supplier. She was selling him the materials cheap.
