 His best remembered book is a posthumously-published novel, "No Love For Johnnie", a cynical portrayal of British politics in the late 1950s which was later adapted into a film starring Peter Finch as the title character.The novel seems to give vent to Fienburgh's deep-seated concerns about corruption in politics - he had previously claimed in 1955 that "the Labour party is the only party in Britain in which you can buy a seat", according to author Michael Rush in "The Selection of Parliamentary Candidates" (1969).One near-contemporary critic writing in the "New Left Review" of 1961 considered it a "bad novel" and that "Fienburgh seems to have had no conception of what idealism means".
