This made sense, in theory. Souls that had passed bureaucratic clearance should not get to wander willy-nilly back into the Fields of Asphodel. It would throw the accounting all out of joint.

Alice should have anticipated this, but still it frightened her, the fact that their paths were erasing themselves behind them. It made the stakes permanent. Either they succeeded, or they died.
