Detective Milo Dragovitch spends too much time boozing until he gets caught up in a case involving two-bit criminals and an old lady on the run.
There--that's all you'll ever get from any James Crumley novel. So take the money you've saved and buy the Library of America edition of Raymond Chandler. That's what you really want.
I've read all his books and still can't tell the difference between Milo and Sughrue. All I know is that both characters have only a marginally superior sense of right and wrong compared to the "bad guys". People who like their heroes clean cut should read Robert Crais' Elvis Cole series.
His later books haven't been as good, but I still read them to keep up on the wanderings of the characters.
If you want a change of pace, read "One to Count Cadence", his first novel.
