Via an analysis of H. G. Wells’s Tono-Bungay, this chapter explores how novels adapted to accommodate the metropolitan spaces of London, and it argues that Wells’s novel links the financialization of the British economy and the cultural turn toward London to the emergence of a new novelistic poetics and to the development of a new novelistic character. Tono-Bungay narrates the rise and fall of Teddy Ponderevo’s financial empire, but the source of drama in the novel is more often the narrator’s inability to reconcile classical novelistic poetics with the logic of value production under finance capitalism and with his experiences in London. The narrator longs for a new mode of representation that can account for the largely imaginary and highly volatile value produced by the financial empire, and he finds inspiration for that new mode of representation in the urban spaces of London.
