“Plum Island” by Nelson DeMille (post 4): More explicit than italics (see prior post), the protagonist says he hears a voice in his head (an alternate personality) and quotes it

“I could also hear a little voice in my head saying, ‘Beware of little men with big rifles.’ ” (1, p. 625).

Comment: As usual for this alternate personality, what it says is a wisecrack.
