June 1915: ‘C’ Flight is ordered to locate a German Howitzer so the artillery can attack it. Alan volunteers, but Captain Dornish insists on carrying out the task himself, taking a newly-arrived observer, Guthrie, on the mission. When they fail to return, a new Flight Commander is required. Charles Gaylion is obliged to become acting CO until a replacement is appointed: Captain Triggers. When his plane fails en route, Triggers finds himself waiting at the railway station with a wounded Infantry Officer, where he learns the horrible truth of Dornish’s fate: shot down by British troops who resented having their positions given away to the enemy. Back in Sussex, 17-year-old Richard Hollis, a member of the local gentry, has been inspired by Alan's progress in the RFC and visits Mrs Farmer regularly to borrow Alan's books on the subject.
