Walk from Shepherd Market towards the Grapes pub. Turn left (north) towards Curzon Street and stop outside Maggs Bros bookshop. Opposite you can see both Heywood Hill bookshop and Trumpers barbers. After listening to my piece on John le Carré, head east and then south along Half Moon Street and stop at Flemings Hotel. To get home, you can catch a bus on Piccadilly or head to Green Park tube on the Jubilee line.

You can follow the route on Google Maps... (https://goo.gl/maps/v1h9gLVbZjViW38G8)
