In May 1915 the huge ocean liner, the Lusitania, sank off the Cork coast near the Old Head of Kinsale with the loss of thousands of lives. This happened during the First World War. But it was no accident. The ship was torpedoed by a German submarine. Rumour has it that there were spies on board. These rumours were true and thirteen-year-old Finbar Kennedy finds himself caught in the middle of it all. This story mingles fact and fiction in the setting of one of the most dramatic seafaring tragedies ever.
