Mykle received a business education from the Norwegian School of Economics (NHH) in Bergen where he excelled in his studies.

He wrote scripts for their election campaign films and plays for amateur theatre groups associated with the labour movement.

Other short story collections included Jeg er like glad, sa gutten (1952), Kors på halsen (1958) and Largo (1967).

His last published novel was Rubicon (1965), originally thought of as a sequel to the previous two, finishing the tale about Ash Burlefoot.

Three collections of his non-fiction writing were published post-humously in 1997 and 1998, Mannen fra Atlantis, En flodhest på parnasset and Alter og disk.

The court case and the pressure caused by the media attention changed Mykle for the rest of his life, and he became a recluse.

These talks were later turned into the book Mine bøker er musikk: møter med Agnar Mykle ( - My books are music: meetings with Agnar Mykle) The translations of The Song of the Red Ruby gathered tremendous attention outside of Norway, especially in the United States.
