Owen John  Leonard Owen-John (1 May 1918 – 23 January 1995) was a Welsh author of spy fiction who is mostly remembered for his series of novels starring the Russian-born MI-6 agent Haggai Godin. Praised by his comparatively realistic approach to the world of espionage, he has been called by critics "a master of the double cross". These novels star Haggai Godin, a hard-boiled, bon vivant MI-6 agent of Russian ancestry, who is frequently paired with Colonel Charles Mason of the CIA. Each novel is set in a different country.
