Readers may recall that I highlighted the "Dortmunder" series of crime capers in one of my book review articles a couple of weeks ago. The author, Donald Westlake, has died.
He was, as the linked article says, a prolific writer, and his work gave me - and many, many other people - a great deal of pleasure. May God have mercy on his soul and comfort his family.
Update: More on Westlake here (H/T: Captain Heinrichs).
