*** Grifter's Game, Lawrence Block, 1961
This is the first book Block got published under his own name. He does noir as good as anyone, and this novel has all the classic elements, not the least of which is the tone. Joe has the right mix of canny intelligence and world-weary wisdom. Of course, that doesn't save him from falling under the spell of Mona.
If you're a fan of noir, you should check this one out.
