003 – An experienced double-o agent who acted as a trainer and mentor to 007 in the early days of Bond’s double-o career. When 003 goes missing and is reported to be being held at the Olgetsk black site prison, Bond infiltrated the prison to try and rescue him. Bond was surprised to find a 003 that seemed to accept his situation and refused to participate in an escape. After the SAS raided the facility clear that 003 wasn’t a prisoner but was in fact one of the organizers. He was sent to Hellsworth high-security prison [RODAcb].
