I’m having a really bad day. I lost my phone. My purse was snatched. And I got fired . . . by my best friend. But now I’ve got a lifeline. I’ve just been offered a new job. PA to the millionaire businesswoman Mrs Lillian Samson. An amazing salary. Impressive benefits package.

I soon realize there’s something not quite right about Lillian and the company she inherited from her late husband. Sometimes, when she thinks I’m not looking, I catch her watching me with a glint in her eye, like a lion stalking its prey. Some of the things she asks me to do are weird — like volunteer at the local children’s hospital. When I come back, she questions me about the young patients. She sends me on pointless errands, but won’t give me any responsibility. There’s only so many times I can arrange and re-arrange my desk. And things are going to get even crazier. My boss is dangerous. And work is about to get very personal for this personal assistant.
