Peter Robinson's Inspector Banks series goes from strength to strength. In Aftermath he tries something different and pulls it off superbly. In the first few pages we know or think we know what has happened, a serial killer's murder spree has been ended and Banks is tidying up the loose ends. His former lover Annie Cabot is brought in to investigate allegations of undue violence against one of the Police Officers, who discovered the serial killer's secrets in the basement of a surbuban house.
