Single Mum Kate Wilde has escaped an abusive marriage and hasn't had a holiday in years, so when she wins a five-day trip to Paris to learn about perfume - in a competition she can't remember entering - it's a dream come true. Or is it?

Almost as soon as she arrives, Kate's ex texts with evidence that he's in Paris too.

Kate can feel she's being watched, and she's sure someone has been in her apartment. Then she discovers that there's a killer in the city focusing on red headed women like her. And his kill count is rising.

Who should she fear the most?

All Kate's senses are on alert. But can her instincts keep her safe?
