““You can tell no one about this. Not the newspapers, not your aides – nobody whatsoever. If we have any indication that you have told anyone, or indeed have even considered telling anyone, your daughter and grandson will die. If you don’t follow our demands to the letter, they will die. If you don’t agree to all of the conditions we have set out for the summit, they will die. If it becomes clear in the summit or at any other time that others know of this, they will die.””
