In passing himself off as a debauched and sleazy aristocrat, Mostyn Zinctrumpet-Harris has found a splendid way of deflecting the social stigma attached to extreme idleness. Now that he's wanted for murder though and is, rather tiresomely, obliged to clear his name, he will need to become someone altogether other. A Skybum for instance. A nomadic paraglider pilot living out of a glider bag, roaming the skies of five continents to remain forever in the epicentre of the flying season. For these splendid fellows, all time is lost that is not spent flying. In a high octane roller-coaster romp that is by turns thrilling, hilarious and occasionally edifying Mostyn scours the earth for his nemesis and former guru Bertrand Whisted. Finally tracking him down in Australia, Mostyn confronts a conspiracy of perfidious chicanery armed only with savoir faire, a thoroughly blown mind and the race-tuned brain cells of his butler Keanu Reeves.
