Alberta Hitchinson

The place was quiet, that was the important thing, and the sidewalk was deserted. Even Mrs. Alberta Hitchinson, the walker-equipped neighborhood sentry, wasn’t in evidence. I descended from the porch in my limping sidesaddle fashion, started down the walk, turned as if I’d forgotten something, and peered under the steps.

Walker-using neighborhood resident whom Jake describes as a sentry; she is absent when he returns for his hidden gun.
