Erika is at work again, in London after an investigation went very wrong in Manchester where her husband was killed. A girl is found frozen under the ice who turns out to be a wealthy doctor of a powerful and rich family. The family wants to control the investigation's direction and Erika is having none of it and as she digs deeper, she finds it isn't just the one murder she needs to worry about but several. 
 I liked both Erika and the supporting team members and it was a solid read.
