Orin, the hand-model, and the "survey" (pp. 600–601)
The man had looked up at Orin and flicked his eyes slightly past him, at the room behind with pantyless floor and humped covers. Orin was meant to see the glance past him.
Context
The op closes with a tell planted on purpose. The parting glance into the room — over the "pantyless floor and humped covers" — is staged to be caught: "Orin was meant to see the glance past him," the A.F.R. letting the target know he's known. And only "later" does Orin assemble the rest of the evidence the scene has been laying down all along — "the Swiss accent, the absence of a signature-ruse, the Subject's patience with the wait and the absence of gasping when O. pulled the covers abruptly back" — plus the "comme on dit" the door-man drops, whose Swiss-French braids him to the "Swiss" hand-model as one operation. The tells were legible in real time; Orin, whole scene long, files them too late to matter.
