Arrow, London, 1980, reprint.  ISBN 0-09-907900-3.  MMPB, 256 pages.  Very good; wraps show some edge wear, age-toning, sticker on rear wrap; binding sound.  Interior clean and unmarked with tanned pages; some age spotting.  ‘With his own boat, the motor-yacht Seafox, former naval officer Philip Vivian had hoped to earn a living free from the petty restrictions of everyday life, close to the sea he loved.  Now, however, his dream is threatened by financial difficulties.  So when a profitable – if legally dubious – proposition is put to him by an old naval comrade-in-arms, Vivian is willing to listen.  But what starts out as a harmless adventure soon turns into something altogether more sinister.  And Vivian finds himself trapped in a treacherous web of violence and crime, dangerously torn between his stubborn sense of past loyalties and his duty to a society he has always despised.’ (from rear wrap)
