At this point in the novel, it’s still unclear what, exactly, Henry does for a living. He’s some sort of spy, but the details remain hazy—just as hazy, it seems, as his job probably seems to Lelia, who perhaps tired of trying to break through Henry’s protective barriers and finally left to branch out on her own. When Pete suggests that Henry’s the kind of person who would send somebody else to “tail” Lelia, he hints that Henry is unlikely to put himself out there to find out what Lelia’s doing, which is yet another indicator of Henry’s guarded, reserved nature.
