Ruth Rendell: The Thief (UK 2006)

From the Publisher:
Polly was a thief. She didn't steal for money. She stole because she liked it. She began by taking things from people at school, and then from shops. As she grew older, she became more daring, stealing from her friends and employers. She was clever, and she was never caught. But when she goes on a flight to France, she steals something that changes her life forever. Sitting next to a woman who is fast asleep, Polly cannot resist opening her bag and taking a small, beautifully wrapped package. It is only when she opens it that she realizes she has made a terrible mistake. The package contains something that will lead her into extreme danger.
