'You knew,' Flora hissed. 'You knew what was happening to Laurie on board the Arctic Raider, didn't you?' There was a mystery about the boy's death, about the drowning forty years ago on a deep-sea trawler. What really happened? What was the truth about the 'Iceman', the sinister captain of the ship? Why didn't he go back and look for the boy who'd fallen overboard? Who is telling the truth about that fateful Christmas on board the Artic Raider? This is what Flora and Maddy have to find out. Raider was commended for the Carnegie Medal and shortlisted for the Guardian Children's Fiction Award.
