What you pay for by Claire Askew

This 2019 crime-fiction novel is the second book in the D.I Birch series. While the first book was all about a mass shooting at an Edinburgh college, this sees the return of Helen Birch's younger brother Charlie who disappeared from university without trace fourteen years earlier.

The chapters alternate between Charlie's perspective (first person) and Helen's (third person). Charlie is caught up in a case Helen is working on and we slowly find out what he's been doing all these years. It's a great read though there's more violence than the previous one. If Askew writes a third book I'll definitely read it.
