How to disappear and never be found again.
The existence of this owes a lot to greyjoyss's fantastic Gone Girl AU gifset, which you should definitely check out right the fuck now, especially if you're here for the Gone Girl stuff and not endless internal Neiman monologue. It is better than anything I could ever make. This fic's execution diverges so far from that premise that it's not even funny, and the whole thing is less elaborate and steely than Amy Dunne's whole maneuver, but Andrew is doing his best.
The logistics of this do not check out, and the attempt to even handwave them has more or less ensured I will never fake my own death, even for wholly altruistic motives.
