the brother reads the operation

Hal, who cannot see the A.F.R. tail or name the U.S. service, nonetheless diagnoses Helen better than Orin ever will — precisely because he understands personas. He clocks that the "familio-historical profile story" may have been "a dodge," that Orin's fake-married and fake-Jesuit gambits are bouncing off her, and concludes she resists the Strategies "because she knows too much to fall for a persona." He reaches the right read (a professional immune to cover because she runs cover) from the wrong premises (Orin's wounded pride), and files it as fraternal needling rather than counterintelligence. The operative is transparent to the one Incandenza who thinks in disguises, and opaque to the one she's actually working.
