Collins is, of course, the author of the Nolan series of Parker pastiches among many, many other books. He is currently working on finishing unfinished Mickey Spillane novels, at the request of Spillane himself.
This is a great piece. Donald Westlake seems to have touched a lot of lives not just as a writer, but as a human being. It’s so hard to believe he’s gone.
I’m reading Collins’ The Last Quarry right now.
