On a wintry November morning, both the Prime Minister and the U.S. Ambassador receive an appalling ultimatum—a nuclear device, concealed somewhere in London, will be detonated within 72
          hours unless the British and United States governments accede unequivocally to the demand for an independent Palestine. With chilling plausibility, Antony Trew describes how a group of
          ultra-militant terrorists hijack a nuclear warhead, smuggle it into London, issue the ultimatum, and so trigger off a macabre treasure hunt which has the lives of hundreds of thousands of
          Londoners at stake.
