As much as I love reading long novels at times it is refreshing to read a book which cuts through all the complicated twists and turns and long narratives. Rowson narrates a clever story (complete with twists!) without wasting any words. I think it would be an advantage to have read previous novels in the series to understand the relationships between Horton and other characters.
The book focusses on the Luke Felton, a convicted murderer who has been released on license. Felton has gone missing, simultaneously a body turns up in the river. Horton doesn't know whether this body is Felton's or not. As the case progresses we are introduced to other dead bodies as well as remeeting Andy's ex-wife and her new partner.
