Equipped with love, Mr Harold Pye lands on the island of Sark, his mission to convert the islanders into a crusading force for the undiluted goodness that he feels within. The extraordinary inhabitants of the island range from the formidable Miss George in her purple busby to the wanton, raven-haired Tintagieu, ''five foot three inches of sex''. Mr Pye, however, is prone to excess and in the increasingly personalised struggle between good and evil, excess is very nearly his downfall.
