Watch Your Back! is one of the last Dortmunder novels, Westlake’s comic series about an unlucky crook published between 1970 and 2008. Dortmunder and his crew have a sweet lead on an unoccupied penthouse apartment, but their usual planning space, the O.J. Bar & Grill, has been turned into a bust-out joint by the Jersey mob. So now they have two jobs to pull: rob the obnoxious rich guy’s art and save the O.J. Of course, complications arise because nothing ever goes to plan in a Dortmunder book.
