A chance encounter with Armistead Maupin in San Francisco inspired Alexander McCall Smith to write this series of novels based around the fictional No. 44 Scotland Street in Edinburgh’s New Town. The World According to Bertie is the fourth book in the series and revolves around the many colourful characters that come and go at the Edinburgh address. McCall Smith handles the characters with his customary charm and deftness – the stalwart Tory chartered surveyor, the pushy mother, and, most importantly in this novel, the beleaguered Italian-speaking prodigy, Bertie.
