Anthony Price ingeniously combines the machinations of British Intelligence with the legend of King Arthur in an extraordinary thriller that crackles with suspense from start to finish. A US Air Force plane mysteriously vanishes on a flight from its base in Britain, and its ace pilot with it. The CIA investigates the missing pilot, and makes some odd findings - finding that will take British Intelligence officer David Audley back to the 6th century in an absorbing battle of wits with the Soviet secret police.
