Hearing Secret Harmonies is the final novel in Anthony Powell's twelve-volume series, A Dance to the Music of Time.

Nick and Isobel Jenkins let a caravan of four hippies from the Harmony cult, followers of the occult and spiritualism, [4] stay on their land: their niece, Fiona Cutts, daughter of Roddy Cutts; Scorpio Murtlock, an intense young man, also described as "creepy"; Barnabas Henderson; and Rusty.

He gives a speech denouncing bourgeois society, which is interrupted by the Quiggin twins setting off a stink bomb.

[6] Gwinnett had attended as an observer a ritual of Murtlock's Harmony cult, an attempt to summon the spirit of Doctor Trelawney.

Nick and Isobel attend the wedding of Fiona's brother, held at Stourwater, previously the home of Sir Magnus Donners, now a girls' school.

Fiona spots the Harmony cult out for a run on the Stourwater estate, including Widmerpool and Bithel, and invites them to join the wedding reception.

Murtlock ordered his belongings burnt, but Bithel rescued the Modigliani drawing previously owned by Charles Stringham and Pamela Flitton.
