This book investigates the literary imaginings of the postcolonial city through the lens of crime in texts set in Naples and Mumbai from the 1990s to the present. Employing the analogy of a 'black hole,' it posits the discourse on criminality as a way to investigate the contemporary spatial manifestations of coloniality and global capitalist urbanity. Despite their different histories, Mumbai and Naples have remarkable similarities. Both are port cities, 'gateways' to their countries and regional trade networks, and both are marked by extreme wealth and poverty. They are also the sites and symbolic battlegrounds for a wider struggle in which 'the North exploits the South, and the South fights back.' As one of the characters of the novel The Neapolitan Book of the Dead puts it, a narrativisation of the underworld allows for a 'discovery of a different city from its forgotten corners.' Crime provides a means to understand the relationship between space and society/culture in a number of cities across the Global South, by tracing a narrative of postcolonial urbanity that exposes the connections between exploitation and the ongoing 'coloniality of power.'
