10. Ben Horne
Forget all the second-season silliness – the Civil War reenactments, the Pine Weasel crusade. (It's a tall order, we realize.) Fact is, Twin Peaks would not have worked in that glorious run that ended with the killer's unmasking if Benjamin Joseph Horne hadn't made for such a compellingly sleazy red herring. Hotelier, department-store magnate, beloved brother to Jerry, neglectful father to Audrey and Johnny, best friend to Leland Palmer, pimp and predator to Laura Palmer: He was a human nexus of everything wrong with this small American town, and pretty happy about it to boot. Then he discovered there were much worse things out there, and it damn near broke him.
