Championship surfer Dave Tregenza returns to his native Cornwall for a surprise visit, only to find his sister-in-law and aunt in turmoil because Jonathan, his brother, has disappeared without a trace.
Several days later, Jonny’s dead body is discovered on a remote beach just a few miles from the satellite earth station at Goonhilly Downs. The police suspect a link between Jonny and the site, and DCI Channon, with previous experience in suspected sabotage, is called in to help with the case.
The investigation proceeds without success, until a second murder occurs. DCI Channon and his assistant, DS Bowles, two very different men with clashing personalities, must work together to unmask the killer.
