Well this news passed me by.
I only found out about this by chance having seen an article in the Daily Mail saying that he had died earlier this month (May).
A great comedy writer, I read all of his books having picked up (!) "The Virgin Soldiers" when I was about 12.
These books included 3 Virgin Soldiers books (a film being made of the Virgin Soldiers), 4 Dangerous Davies books which spawned several TV series, a couple of autobiographies, several World War 2 novels based on real events plus about 20 others on a vast range of subjects.
His books were a lot more real than the cartoon humour of Tom Sharpe but overflowing with humouous situations.
A great writer in my mind, very sadly missed and a great influence on me.
