The House of the Spirit Levels was a six-part radio comedy series written by, and starring, Nick Revell. It was a surrealist satire on big business and Northern family sagas with Revell playing the long-lost son of the Hardstaffe family who gets caught up in their business machinations. It was told in flashback from South America and did not end happily. It is occasionally rebroadcast on the digital channel BBC Radio 4 Extra.
