Just had this inspirational brainstorm. I was reading and thinking about "Life On Mars", and thought about this idea for a story...
Take a detective from New Orleans, who's partner just died. She's wanting to find out who killed him...and she has a new partner.
He's very much an "old school" cop. He dresses as much as you can, like he was from the '70s. He "interrogates" people in ways that a lot of cops aren't allowed these days. Has problems with cell phones and computers. Is a "bit" dirty (there's two scenes that reflects this-one is when she meets him, he's eating a meal, and the guy that owns the resturant won't take her money, cause "she's his friend". A second incident is when a guy tries to slip him a $100 to make a problem go away-he lights the bill on fire and stuffs it in the crook's pocket).
In short, he seems like he was resurrected from the '70s.
Which he was.
It turns out (we'll learn this as the series goes on) that he died in 1976, killed by six people-two he didn't know, his old partner, and three other people. All to keep the secret of a land deal that made them millions. When Hurricane Katrina hit...he came back from the dead.
By the end of first season, we learn that when he "brings to justice" the six that killed him, he gets to go on to Heaven. If he gets killed again (which can only happen if his head is cut off), he goes straight to Hell...
Interesting bits of drama, and there's also the whole "duck out of water" aspect to the story.
