Two Dickens novels, one city of thieves' dens, prisons and cramped lodgings. Oliver Twist is dragged into Fagin's gang in the lanes of Holborn, while Pip of Great Expectations arrives from the Kent marshes expecting a soft white city and finds filth.
The route follows Oliver and Nancy from Saffron Hill to London Bridge, Jacob's Island and Newgate, then Pip from Cooling churchyard through Rochester to Little Britain and Barnard's Inn. Several places are traditional models rather than named settings, and each pin says so.
In 1973 Paul Theroux set out from London Victoria on a four-month railway loop through Europe, the Middle East, the Indian subcontinent and Southeast Asia, then came back on the Trans-Siberian Railway. His travelogue, published in 1975, became a classic of the genre.
This route follows episodes the book's reviewers single out, from the Direct-Orient Express to Istanbul, Calcutta, Burma, Vietnam and Tokyo. The book's own text could not be checked, so some pins mark a city's station rather than a scene, and some places are not safe to visit now.
