A suicide bomber from the Palestinian Islamic Front for Jihad and Liberation (PIFJL) tries to blow up Waterloo Tube Station in London. Thanks to the efforts of the Mossad, the Semtex bomb fails to detonate, but it explodes later in a PIFJL safe house. Leaders of the PIFJL need a new place to set up base, and choose a remote Greek island.
However, members of the anti-Moslem Greek Spartan League intercept the motor launch carrying the PIFJL explosives and weapons. When the League sees a letter describing the British Government’s secret plans to recognize the Turkish occupation of Northern Cyprus, leaders plot retaliation using the stolen munitions.
Despite the best efforts of MI5 and the Mossad, London’s Tube commuters are once again in serious danger.
