Murder: One, Two, Three — John Creasey

There have been two gruesome murders in a quiet Sussex seaside town and Roger ‘Handsome' West of Scotland Yard is called to investigate. Lefty, who kills without a thought for his victim, believes only one further frightened girl stands between him and a small fortune. West struggles with the case, and is nauseated by the brutality of the killer, but he must solve it and quickly.
