Tonight, Philip Dodd and guests reflect on safe cities, past and present - on how literature, technology, law and social engineering imagine safety and its absence in cities - and whether safe cities are in the end an oxymoron.

Philip is joined by senior urban fellow at LSE Cities, Adam Greenfield, writer Beatrix Campbell, criminologist Peter Fussey, director of The Runnymede Trust Omar Khan, and historian of London Jerry White, who will be discussing Joseph Conrad's terrorist novel, The Secret Agent.
