Secrets are leaking out of Cipher HQ like a sieve, but all of the employees insist that everything has been "perfectly normal." However, The Avengers find a link between the stolen information and a window cleaning service.
Several operatives from MI12 have gone missing, the latest being Roger Jarret. When the avengers arrive at his flat they find his corpse but are observed by window cleaner Maskin, who works for the Classy Glass window cleaning agency. The avengers visit the company's offices to be told that they had given up the contract to clean MI12's windows some time ago. However they soon discover that somebody is using the privileged position of being able to spy on spies undetected and expose the leader of the gang.—don @ minifie-1
