When
/RichardHalley disappeared he had written only four concertos. In
/SectioN112 /DagnyTaggart, and enthusiastic fan of
/RichardHalley's music, hears an unfamiliar theme being whistled by a
/BrakemaN on the
/TaggartComet. She asks him what it is and he says Halley's Fifth Concerto. When Dagny says Halley only wrote four concertos, the
/BrakemaN says he made a mistake and denies knowing what the song was.
Later, Dagny calls /MrAyers to find out if Halley wrote a fifth concerto. He says he did not.
