Jim Brady’s death brought to mind a wistful moment in The Prince of Darkness, the late Robert Novak’s priceless memoir. On March 23, 1981 — one week exactly before John Hinckley shot bullets into President Reagan and his press secretary — Novak and his partner Rowland Evans sat down with Reagan in the Oval Office for a 30 minute interview. Novak had called Brady to request it, and to his surprise Brady was the only aide present, and he left after five minutes. “We were alone with the president,” Novak writes, for another 30 minutes it turned out. At which point, Brady returned, “hand-signaled” to Novak that time was up but gave him and Evans five additional minutes to wrap things up.
