A reunion of Spitfire pilots from the Battle of Britain in a Kentish country hotel, and an overgrown rockery garden covered with bluebells combine to spark off one of Georgia and Peter Marsh's most dramatic cases. They discover that a murder had taken place in the 1970s; the victim was a popular war hero, Patrick Fairfax. His murder had never been solved. Convinced that there is a story here, the father and daughter Marsh team is driven to find out what happened. As well as the Spitfire pilots, the reunion included several members of the aviation club Fairfax ran after the war, and not all of them had cause to love him. Fairfax' memory is still green: his family keeps the flame burning, a film is in production, and his classic story of the Battle of Britain is to be reissued. What Peter and Georgia discover, however, sets in train of events that leads to a second murder, as the passions of today boil over to prevent the truth from emerging.
