Bad Chili, by Joe E. Landsdale

Landsdale has written some outstanding books -- The Bottoms (2000), Sunset and Sawdust (2004), Lost Echoes (2007), and Leather Maiden (2008), to name a few.  But I just don't get the appeal of the Hap and Leonard books.  They are so raunchy, so unlikely, and unsubtle.  In this book, Hap is bitten by a rabid squirrel, falls in love, and must find the killer of Leonard's lover Raoul.  Not to mention the torture, tornado, and many headless corpses.  And the violence, unending and grisly.
