Sounds like our main character might not be a Blade Runner in this, then. Interesting.
So much noir isn't told from the POV of the detective, so this strikes me as a very valid angle to go here. And with the comment that the (presumably Replicant) lead has to team up with a Blade Runner that is nearing the end of her own life, that initially makes one think that the Blade Runner is also a Replicant with a set expiration date, but I wonder if perhaps she might be human and dealing with a sickness/disease in which her own days are numbered, which would bring her that much closer to the prey that she is being sent out to ruthlessly hunt down.
