If you're not as happy as you'd like to be, is it because you possess too little - or because you possess too much? Peter France meets a millionaire, a pauper, three young people who have chosen to live the poor life, and Mother Theresa of Calcutta, to investigate the claim that the secret of happiness lies not in wealth but in poverty. In Assisi he finds out what has happened to the ideals of the most famous 'poor man' of them all, St Francis, 750 years after his death.
