Harry forgoes the quick convenience of an Apparition or Floo journey and walks along the Thames Path instead, all the way from Waterloo Bridge to Wapping High Street. He passes throngs of tourists outside Somerset House; he wanders the spookily quiet City, where the towering, shiny office buildings are empty bar the few overworked bankers clocking in weekend hours; he pushes through the crowds at Tower of London and Traitors’ Gate; walks by families enjoying lunch and the early autumn sunshine at St. Katharine’s Docks. All the while, h is phone is a burning stone in his pocket.
