I'm looking for the name of a book written by a British teenage author in the 1970's?

The author in question was male and as I remember was the son of a famous Jazz musician. The book was set in England and told the story of a boy who discovers a secret society made up of his fellow pupils who are plotting to take over his school. The secret society is being run by a girl who goes by the code name of Mistress K and part of the story involved them secretly re-enforcing the roofs of the school buildings to allow helicopters to land. I reckon it was published between 1976 and 1982 so if anyone could help I'd greatly appreciate it, thanks.I'm looking for the name of a book written by a British teenage author in the 1970's?
