The Twelfth Commandment - Paul Cranwell

On the face of it, Peter Steadman is a successful banker. Happily married with two children he lives a luxurious lifestyle. But he has both a roving eye and an expensive gambling problem. Targeted by international money launderers, he is caught in a honey trap. Faced with exposure and the loss of everything he holds dear, he begins to authorise dubious money transfers. Then he is approached by a group who want him to help bring down the blackmailers. If he doesn't assist them he faces exposure and gaol. On the other hand, if he assists them and the blackmailers find out, then he and his family may well be killed.
