Gately mute in the Trauma Wing (p. 810)
The room’s only light was what spilled in from the nighttime hall. Nurses glided down the hall and past the door in subsonic footwear. A tall and slumped ghostish figure appeared to Gately’s left, off past the blurred seated square-head boy’s bed, slumped and fluttering, appearing to rest its tailbone on the sill of the dark window. The ceiling rounded on down and then settled back flat.
Context
The wraith's actual first appearance in the book, one scene before it's named: tall, slumped, fluttering, tailbone on the windowsill — exactly the posture and position the "garden-variety wraith" of pp. 829ff will hold for its whole bedside seminar. On this first night it's indistinguishable from the fever's other ghostish figures; scene 162 retroactively confirms this one was JOI, waiting.
