The Hot Spot — Charles Williams

A dark, brooding masterpiece of guilt, greed, and lust in a town ripe for felony.

Madox wasn't all bad.  He was just half-bad.  But trap a man like Madox in a dead-end job in a stultifying small town, introduce him to a femme fatale like the Harshaw woman, and give him a shot at a fast fifteen thousand dollars--in a bank just begging to be knocked over--and his better nature doesn't stand a chance.

Merciless in its suspense, flawless in its grasp of the ways in which ordinary people hurtle over the edge, The Hot Spot is a superb example of fifties roman noir.
