At eighteen, your closest friend commits suicide.
At twenty-nine, you're backpacking in the Australian outback when you see her. She has a husband. She has a ten-year-old son. She has a baby on the way. She claims to be someone else. But you'd recognise her anywhere.
Back in England you tell your journalist boyfriend. While he never knew her, he always knew of her - her name is Daisy Fraser and she was awaiting trial over the deaths of four people when she jumped off the Severn Bridge. He thinks: This could be the scoop of the century. He says: Happy Christmas - I'm taking you to Australia to find Daisy.
