《無有鄉》(Neverwhere, 1997)原為BBC迷你影集，後經由作者尼爾‧蓋曼(Neil Gaiman)改寫成小說，書中主角理查‧馬修(Richard Mayhew)因拯救朵兒(Door)而被迫開始探索他前所未知、無從想像的倫敦空間，也就是倫敦下層(London Below)。此倫敦空間充滿暴力混亂，顛覆理查對原有倫敦的想像，也將他帶離熟悉的畛域，雖然倫敦下層的事物希奇古怪，卻又詭異的與倫敦上層互相指涉，也使理查此旅行充滿詭異怪誕(uncanny)。此論文意旨爬梳倫敦城市空間的複寫性和其造成的詭異、探討理查馬修漫遊者(flâneur)形象以及理查結尾做出的看似自由卻又充滿侷限逃逸線(line of flight)。 / In Neil Gaiman’s first novel Neverwhere, adapted from the original namesake BBC television serial, the protagonist Richard Mayhew is a forced traveler, exploring the territory of imaginary London Below, in which Richard fails to grasp the sense. The “London Below,” the buried and repressed past by the “London Above,” is full of chaos, violence. Observing the invisible cities of the multiple other which used to escape his unitary way of seeing, Richard’s vision of the familiar/homely city gets blurred, defiant. However, events in London Below always disturb but at the same time uncannily refer to those of the London Above, which makes his journey in London Below an uncanny one. This thesis is going to discuss palimpsestic London space and the role of Richard Mayhew as flâneur and Richard’s final decision as a line of flight.
