Skellen manages to separate himself from the group by feigning a need for the toilet. He uses a shaving mirror to heliograph floodlights and signal Hadley via Morse code, telling him to attack at 10 a.m. while Skellen creates a diversion. Hadley cannot get permission for an SAS attack because the British Home Secretary insists that Powell resolve the situation through negotiation. As the tension mounts inside the embassy, a mistake by one of the terrorists causes the death of the SAC C-in-C. This enables Powell and Hadley to get the permission for their assault.
