I actually read Farewell, My Lovely (his second book) first, so I was a bit rearranged in Marlowe's timeline. But it doesn't really matter--Chandler hits it out of the park again.
This time, Marlowe is assisting a millionaire invalid whose two daughters just can't seem to stay out of trouble. We have the shady dames, nogoodniks, twisty plots, and completely gorgeous language that are the Chandler hallmarks.
I would have loved to see Southern California in the 1930s and 1940s--with Chandler, I feel like I have. Read this one, too, people.
