Echoing his journey in London Orbital over a decade ago, Iain Sinclair narrates his second circular walk around the capital. Shortly after rush-hour and accompanied by a rambling companion, Sinclair begins walking along London's Overground network, or, 'Ginger Line'. With characteristic playfulness, detours into folk history, withering assessments of the political classes and a joyful allegiance to the ordinary oddball, Sinclair guides us on a tour of London's trendiest new transport network - and shows the shifting, changing city from new and surprising angles.
