Pseudonym: Maxwell, Ian
11/23/63 memo from Pete Bagley, recounting a chief from SR Division, sent from Frankfurt, for the attention of Mr. Angleton: "I discovered from Arthur Martin (of MI-5) during our long and exceptionally valuable conversations, that one of Harold Wilson's principal scientific advisors is Captain Ian Maxwell, who has a long Soviet intelligence background. This may shed new light on AELADLE/Anatoliy Golitysn's report (i.e. that Harold Wilson may be a Soviet agent)..."

Like Angleton, Bagley believed in Golitsyn’s theory of the “Monster Plot” – that the entire Sino-Soviet split was a fake maneuver designed to lull the West into dropping its defenses and making itself vulnerable to the Communist menace. Bagley went so far as to write in his November 23 memo that “one of Harold Wilson’s principal scientific advisors is Captain Ian Maxwell, who has a long Soviet intelligence background. This may shed new light on (Golitsyn’s) report, i.e., that Harold Wilson may be a Soviet agent.” Like Bagley, Mexico City station chief Win Scott was a “Fundamentalist” – one who subscribed to Angleton and Golitsyn’s school of thought about a monolithic Communist threat – and it’s no accident that Scott’s pen name for his Mexico City memoirs was Ian Maxwell. Scott did not want Maxwell to be forgotten.
6/14/67 memo from C/WH Thomas Lund to Mexico City chief of station "Willard"/Win Scott: (at p. 2) - the table of contents refers to Chapter XXIV of Scott's manuscript "The Foul Foe" - "the writer is 'Ian Maxwell', believed to be the pen name of Winston M. Scott." (p. 3): "It would be unfortunate if LIOSAGE (note: Carl Migdail, staffer with the US News & World Report and David Phillips' friend) were to learn that we were privy to his information - in particular, what Scott had said to him. "We have received from a very sensitive source two pages only of a letter (Attachment A) almost certainly by LIOSAGE to his home office reporting of comments he claims made by you." Marginalia apparently written by Scott: "Letter in my personal file." "NOT BY ME." Both comments initialed by "wcc", the initials of his pseudonym Willard C. Curtis.
Description of the early 1970s book "The Foul Foe" - "by Winston Scott writing as Ian Maxwell."
Note from CIA states as follows: "Chapter XXIV from draft manuscript of 'The Foul Foe', book which purports to be an account of the writer's career in intelligence. The writer is 'Ian Maxwell', believed to be the pen name of Win Scott." The chapter makes the remarkable claim that "every piece of information concerning Lee Harvey Oswald was reported immediately after it was received to: U.S. Ambassador Thomas Mann, by memorandum; the FBI Chief in Mexico, by memorandum; and to my headquarters by cable; and included in each and every one of these reports was the conversation Oswald had, as far as it was known. These reports were made on all his contacts with both the Cuban Consulate and with the Soviets." It should be noted that this statement by Scott is not supported by the CIA's documentation of Oswald's visits, which does not include any reference to Oswald's visits to the Cuban consulate and his relationship with the FPCC until after the assassination.
