HERE is the eighth in the D. S. McAvoy series of novels written by the Northumberland-based writer, who spent his years as a crime reporter walking the streets of Hull, and it is set in the tightknit fishing community of Hessle Road in that city. Hull and Iceland have traditionally been linked by fishing, and in this case they are connected by a secret concealed for half a century, and a series of brutal killings that have never been connected.
