Meet Hap and Leonard, the unlikely detective duo now on screen in the highly praised series starring James Purefoy, Michael K. Williams and Christina Hendricks.

If there's one thing Hap Collins and Leonard Pine like, it's trouble - and they especially like getting paid to find it.

So when their friend and sometime boss Marvin Harmon asks the boys to look into a cold-case double homicide, they're happy to oblige. It turns out that both victims were set to inherit some serious money, and one of them ran with an honest-to-goodness vampire cult.

The more closely Hap and Leonard look over the crime scene photos, the more trouble they see. The image of a red devil's head is painted on a tree. A little research turns up a slew of murders with that same fiendish signature. And if things aren't weird enough, Leonard has taken to wearing a deerstalker cap... Will this be the case that finally sends Hap over the edge?
