Is it just me or does Parker not really describe any of his recurring minor characters beyond Hawk and Susan? Yes, Vinnie Morris and Zebulon Sixkill are physically and ethnically different from Chollo, but do they stand apart from each other in your mind? Same with Belson, Quirk, and most of the cops (Lt. Samuelson, Lt. Corsetti) who've helped Spenser in the series (when he was in L.A. or New York City).
What do you think about that?
