In the half a square mile of decay and demolition that was England's Saxon capital, eternity is loitering between the firetrap tower blocks. Embedded in the grubby amber of the district's narrative among its saints, kings, prostitutes, and derelicts a different kind of human time is happening. An opulent mythology for those without a pot to piss in, through the labyrinthine streets and pages of Jerusalem tread ghosts that sing of wealth and poverty; of Africa, and hymns, and our threadbare millennium.
