Wild premise, engagingly treated. Very short.

If someone kills you, you don't die; you just vanish, and reappear naked and alive, in your bed at home. Almost always! So, if someone is gravely injured in an accident and about to die, what do you do? Have someone come in and kill them, of course!

Given this rather unique background, we have what is basically a noir detective story, that plays nicely with the bizarre setting, but also hews to the genre.

Very very short. Novelette? Longish short story? I'd enjoy an actual novel set in this universe.
