The Berlin Wall, a brutal, iconic structure made of concrete and barbed-wire, rose to split a city overnight in August 1961. Then just as quickly, and again overnight, it was breached in November 1989 when glasnost spread through eastern Europe. As an impressionable student in the Eighties, hungry for icons, not brutality, I found that the Wall cast a compelling spell. And if my grant couldn’t get me to Berlin at the time, then cultural touchstones worked instead. There was the music of David Bowie (whose albums Low and Heroes were made at the famous Hansa studios, by the Wall). There were certain fashions to follow (baggy coats and macs, surely the attire of spies). And, of course, there were books to devour, with accounts of the Wall covered by most genres. So, with twenty years approaching since that momentous breach, what would I read again to mark the event?
