After several less than successful encounters, he meets an old friend, Nick Nightingale - now a musician - who tells him of strange sex parties when he is required to play the piano blindfolded. All the men at the party are costumed and wear masks while the women are all young and beautiful. Harford manages to find an appropriate costume and heads out to the party. Once there, however, he is warned by someone who recognizes him, despite the mask, that he is in great danger. He manages to extricate himself but the threats prove to be quite real and sinister.
