Katie Petherick is young, beautiful and successful, but not content. For three years she has been earning a good living as an upmarket live-in maternity nurse, working closely with wealthy couples and gaining their trust. It is not enough. Now it is decision time. Katie has a devious plan to make some serious cash, but there is considerable risk. She knows she is playing with fire, and she realises people are likely to get hurt – not least her boyfriend, Peter Dunkett. He is crazy about her, and he is too scrupulous ever to be happy about what she has in mind, but his need for money is even more pressing than Katie’s.
