Big-time businessman Sir Gerald Campion is losing money. The losses in his gambling division look like an inside job. He's angry, and betrayal like this can't go unpunished.

He enlists the help of Shannon Investigations, a team of fraud detectives with a reputation for getting results - and fast.

Wasting no time, Nick heads to the casino to gather intel and spots shady dealings at the blackjack table . . .

Nick's onto something. But before he has time to act, he's attacked by a mad axeman waiting for him in the carpark, backed up by an unknown figure in a van.

Then a car bomb explodes, killing one of Campion's staff and injuring one of Shannon's own team.

Someone is playing a game of Russian roulette . . . And Shannon's going for broke.
