"she walks up Kingsway"

 Kingsway is one of the broadest streets in Central London and runs from Holborn in the north to Aldwych in the south. It was not actually built until 1900 – a part of the area redevelopment which cut through the former maze of small streets in Holborn – and had a tunnel for a tram system running underneath it. The original buildings were built between 1903 and 1905 and include offices such as the Civil Aviation Authority and buildings belonging to the London School of Economics.
