When is dead, dead, in the Dresden Files? I can write any number of scenarios that work. But what was the point of killing him if you are just going to resurrect him?
Death loses its gravitas if it is never, really final. Murphy got killed. Butcher uses it for the emotional punch. And then he resurrects her. The whole scene with Rudolph turns out to be about Harry losing his shit because Rudolph made his girlfriend go away. Not because she died, because, well, she didn't.
