Ratwarmer

Tim is a ratwarmer.  He has the power to bring people back from the dead.   During the FlipSwitch, some people got some powers. Tim got the power of reanimation.  It's not as great as it seems.  He works for the police. He brings recently dead victims back so they can be a witness to their own death. That's what a ratwarmer does.  It doesn't work well, but it's worth a try.  Now, there is a murder in town.
The wife a wealthy man. Tim knew this woman. And now he will have to bring her back.   There is a world of corruption that only the dead know and Tim can get them to talk.   There is a dead body so it's a mystery. People have strange powers so it is a fantasy. There are reanimated bodies, so it also could be a horror.  But what it is, is the story of a guy not sure of his place in the world. A strange world, but it is the only we he has.
