To most who knew him, Herman Rockefeller was a respectable multimillionaire company director.

A highly intelligent father-of-two who was involved with the local church.

Mr Rockefeller, a Harvard graduate, was a fitness fanatic who would run 15km a day and lived in a mortgage-free mansion in East Malver.

He had held senior business positions with companies including the Pratt family’s Visy empire.

But there was another side to Mr Rockefeller, which he kept secret from even his closest friends and family.

It involved secret phones, aliases and sex. And it cost him his life.

Using the name Andy Kingston as an alias, Rockefeller placed an ad in a swingers magazine.

It was answered by Bernadette Denny, who picked up the magazine at a Sexyland store.

Denny thought their initial contact sounded promising, with Andy Kingston telling her he and his wife were regular swingers.

“He was saying how they – they swing, him and his partner swing. That she likes to do it – you know, she likes – she’s more into the threesome, but she’s willing to try the foursome,” she said.

“He sounded like he’d done it all before.”

They met for the first time in December when he went to her Hadfield home and they had sex while her partner Mario Schembri watched.
