There is a spy/thriller novel, --Orchids for Mother-- by Aaron Latham,
set at the CIA in which "Mother" is the code name for a character based
on the notorious CIA head of counter-intelligence, James Jesus
Angleton, a man obsessed to the point of paranoia with the presence of
"moles" within the agency. Mother, like the real Angleton, is an
orchid fancier, though the novel has very little to say about that.
