Just through the post. 'The Cutie' from Donald E Westlake (aka Richard Stark from Parker fame). These books from Hard Case Crime are superb!
I have a few more on their way. They are great to stick in a jacket pocket and even have books by Lester Dent.
Makes me want to reread the Darwyn Cooke Parker books and maybe stick 100 Bullets back on the read pile (again).
