The intrepid O'Hanlon describes, largely by means of dialogue, his latest journey - on a trawler sailing from Stromness to Greenland. With a terrifying overdraft, captain Jason and his crew of 6 tough Scotsmen are compelled to sail in a Force 12 (junior hurricane); unable to fish the North Sea or Icelandic waters their journeys become longer and more dangerous, in search of ever stranger fish, like the anglerfish. O'Hanlon's knowledge of evolution and C19 science gives depth to this powerful account.
