Charles McCarry(1930-2019)

In 1965 he interviewed Michael Caine about his experience playing a secret agent in the film 'The Ipcress File (1965)'. At the time of the interview, McCarry himself was secretly employed by the CIA.

Explaining the meaning behind "deep-cover" in deep-cover agent: "Oh it's laughable... What it means is that you have an ostensible occupation, a cover job, and that you don't go about introducing yourself as a CIA agent. You don't work out of an embassy, in fact you don't go near an embassy, and all of your meetings and reporting take place clandestinely."
