Kitt knows there is no way Evie could murder anyone - let alone Owen, who she adored. Horrified that the police could have got it so wrong, Kitt decides there's only one thing to do: she's going to investigate Owen's murder herself. She's read hundreds of mystery novels - how hard can it be?

She soon discovers that down the quaint streets and snickelways of York lie darker doings than she'd ever dreamed, but she needs to watch her step: the murderer is watching her. And they haven't finished killing yet....
