So how the heck did it get to be 2017 before I found out Parker had written a Spenser short story way back in 1982? Beats me! I just happened to see a short story listed on a Parker bibliography (not identified as a Spenser) and tracked down a copy of its first reprinting, in the 1991 anthology New Crimes 3. To my further embarrassment, I now find it was reprinted yet again in Boston Noir 2: The Classics in 2012.
In "Surrogate," we learn that Brenda has since been unhappily married and divorced. Spenser calls Hawk for help, and, with their usual aplomb, they bring the case to a satisfactory conclusion. No, it's not particularly great stuff, and it's not essential to the canon, but it is a genuine Spenser story, and to a superfan like me, cannot be ignored. This is me not ignoring it.
I'm relying on internet pics and descriptions because the regular edition now commands between $400 and $1000, and two folks offering the deluxe job are asking $2500. Superfan yes, superrich no.
