In "The Secret Servant" by Gavin Lyall, the character of George Harbinger, a civil servant, is given to referring to the intelligence services of Warsaw Pact member states in Bunteresque language, using "cads and rotters" to indicate their agents in the UK, and "Greyfriars" to indicate their various headquarters (particularly the Lubyanka Building as the activities of the satellite states' services are assumed to be directed by the KGB).
