«The British Secret Intelligence Service, known variously as SIS and its military intelligence cover designation, MI6, maintains a strong tradition of secrecy. None of its staff are allowed to write books or give interviews, and the much misunderstood ‘thirty-year rule’ does not apply to the organization. Yet, in spite of these apparent barriers, ‘the firm’, as it is referred to by insiders, enjoys a unique reputation for stealth, devious efficiency, ruthlessness and, it must be said, treachery.» — fra introduksjonen
