This is a reference book that details the 86 episodes of the British made TV series Danger Man, which was known as Secret Agent in the U.S. It starred Patrick McGoohan as secret agent John Drake, who originally works out of Washington for NATO, then switches to work for London's M9. The series ran 1960-62 and 1964-67.

The book includes complete cast listings, directorial credits, numerous photographs, story synopses, and original air dates-those being the first showings in the U.K. Internet sources often confuse these dates as some sources list those dates either in the U.S. or other countries, which were in general later than the original showings in England.
