Norman James Crisp (11 December 1923 – 14 June 2005), known as a writer only by his initials and surname, N. J. Crisp, was a prolific British television writer, dramatist and novelist. In the sixties after writing some single dramas, Crisp moved to writing for serials and turned out scripts for many BBC series including Compact, R3, Dixon of Dock Green, Dr Finlay's Casebook, Colditz and Secret Army. In 1968, he co-created The Expert, a serial about a forensic scientist, with its producer Gerard Glaister. Four years later the pair repeated these roles with the boardroom drama The Brothers.
