Sanders has written a great number of mystery novels. While many are similar in style, they do not necessarily share the same characters or settings. In addition to The Sixth Commandment, Sanders has written The Tenth Commandment (1980), The Eighth Commandment (1986), and TheSeventh Commandment, (1991). Contrary to what one might assume, these novels do not constitute a series. What they share, apart from the brand name, is a similarity of style and narrative invention.
