The Edge of the Crows

London, 1851. Among the teeming crowds visiting the Great Exhibition is the newspaper columnist Henry Hilditch, whose sensational exposés of the lives and deprivations of the working class are the talk of bourgeois London.

But Hilditch has another agenda. Mary Medworth, the love he lost the previous summer in Florence, has reappeared somewhere in the slums of London's East End. Hilditch follows the trail from the splendour of Hyde Park to the squalor of Whitechapel, encountering thieves, gaolers, kidnappers and false friends who may well lead him to his own destruction.

The photographer Cornelius Touchfarthing is Hilditch's last link to Mary. But Touchfarthing is preoccupied with his own ambition ? to create an image so astonishing it will elevate the trade of photography into High Art.
