When 17-year-old Matt dreams that he is a World War 2 pilot in a dogfight against the Germans, something strange happens. Was it a dream? Because later that morning, the family gets news that Grandad died at exactly that time, 3.15 a.m. This is the beginning of a bewildering set of adventures, into which Matt is plunged. At Grandad's funeral, two of his old squadron mates turn up and he becomes aware that there is a cloud over Grandad's name, something that happened in the last days of the war, and to do with the death of his Squadron Leader, Jingo Brook. After the funeral, Grandad's house is trashed. With the help of a local 'bad boy' Matt discovers who did it and what was taken - his grandad's log books and journal from WW 2. The second part of the novel is Grandad's story, told in the first person, when he was a little older than Matt. He joins a Tempest ground-attack fighter squadron, operating in Germany, in the last months of the war. Matt, financed by his grandad's estate, goes to Europe and, on the banks of a northern Holland canal finds the evidence that clears his grandfather's name. Now the skies above are blue and quiet but he has won his Grandad's last victory.
