Farewell My Lovely, by Raymond Chandler

I've read this book at least twice before, but I picked it up for fifty cents at a used book sale, and can't resist reading it once again. Moose Malloy is looking for Velma. Mr. Marriott has an easy job for Marlowe, just be there when he hands $8000 to a bunch of jewel thieves to retrieve a friend's necklace. What could go wrong?
