Books like Apathy and Other Small Victories

The only thing Shane cares about is leaving. Usually on a Greyhound bus, right before his life falls apart again. Just like he planned. But this time it's complicated: there's a sadistic corporate climber who thinks she's his girlfriend, a rent-subsidized affair with his landlord's wife, and the bizarrely appealing deaf assistant to Shane's cosmically unstable dentist. When one of the women is murdered, and Shane is the only suspect who doesn't care enough to act like he didn't do it, the question becomes just how he'll clear the good name he never had and doesn't particularly want: his own.
