Note: If you haven't bookmarked this site yet, you seriously should: The Violent World of Parker has a veritable cornucopia of information on all things Richard Stark and provides far more intelligent commentary than I could ever hope to give. It's also the source from which I shamelessly stole the covers that illustrate this review.
Of particular interest to this review is an introduction to The Score written by William L. DeAndrea, another author I highly admire. If I haven't convinced you to give this series a try, read what DeAndrea had to say about it.
The Score was also published under the alternate title Killtown. It's also been adapted into comic book form by Darwyn Cooke, who has also adapted other Parker novels into comic book form. The project was given Donald E. Westlake's blessing, and these are apparently faithful adaptations. If anyone has read them, I would appreciate any comments you might have.
