When an ordinary British fishing vessel and its 36-man crew mysteriously disappears off the coast of Norway, journalist Martin Taylor is determined to find out why. His father was on board, and is now missing. His investigations soon lead him to run up against the twin barriers of Royal Navy stonewalling and an impenetrable Soviet Politburo.
