Skiing was Hamish Watson's great love. Before he was a puffed-up futures trader in Sydney, he was a pumped-up muscle-bound ski instructor, in Australia and Canada.

Hamish arrived in sleepy Blueys Beach with a beautiful woman on his arm, and on the run from his past. Rumours of dark deeds wafted through in his wake. Then he met Bec Rosen. He'd shower her with love. They'd be married on the balcony of a beach shack. He'd become a father figure to her boys.

And then he'd cruelly betray them all.

Hamish McLaren was always attracted to the high-life. It was inevitable he'd gravitate to fashion. And so, nestled among the retirees and energy healers, Hamish stole from was another name: Lisa Ho. But had Hamish met his match in this high profile Sydney designer?
