Thanks, Synamon! I thought I couldn't be tempted right now....
I've read most or all of the series from the following authors, and can recommend them highly if the description sounds interesting:
James W. Hall (Under Cover of Daylight), Donald Westlake (Hot Rocks) (of course), Robert Tannenbaum (No Lesser Plea), and Brian Freemantle (Charlie M).
The Freemantle series is perhaps the only one that requires description beyond that offered by the listings: This is NOT an 007 or Bourne style spy story. Lots of intricate and subtle plotting, mental double-crossing and triple-crossing, and not much in the way of big action scenes. Incredibly well done, but not what some people might expect. (Well, it wasn't what I expected, but fortunately I read it anyway-- and haven't missed one since.)
