Query: Faceless killers

After seeing the BBC series on Masterpiece Mystery, all I have wanted was more stories about Kurt Wallender . Mankell's books give a deeper and broader scope into Kurt's life besides the murder at hand,which makes this book hard to put down. Faceless Killers is a very police crimemurder mystery.I can't wait to start reading the next book in the series
