Another way to unlock this achievement is to hide outside the window of the meeting room, and shoot Campbell with a sleeping dart from a hidden angle. Curnow will then run away, and after a while you'll get the message that he's saved.

It is recommended that you deactivate the alarm in the corridor outside, as the place will go into lockdown as soon as the klaxons start klaxing. If deactivated, Curnow will run away and the guards will return to non-alert status after a while. Leaving you free to snatch the black book, and the unconscious Campbell, should you want to go non-lethal.
