Good news for fans of Ross Macdonald. By the end of next April, all 18 of the Lew Archer novels will be back in print. I've only read two Macdonald novels, on Dave's advice, but I'm a big fan of his. As any fan of his will tell you, Macdonald is as important to the hardboiled genre as Hammett and Chandler are. His Archer novels started out in the pithy style of Chandler, but added psychological depth and insights into the motivations of his characters that were seldom seen in the genre until that point.
If you haven't read any Macdonald, go check him out. You'll become a fan.
