Digging needed guise. Gareth Williams (the spy in a bag) had hacked Bill Clinton. The Clintons may be connected to his death. This really upset his boss, the Head of SIS, Sir John Sawers.
Funnily enough, there were no records kept of Sir John Sawers questioning by police.
Look into this guy Sir John Sawers, Head Of SIS please.
