The Turkish translation of Nick Dunn’s “Dark Matters” explores the nighttime city as a time-space where you can escape from the confines of the daytime. The night city represents a special way of being. Nightwalking has often been integral to shady worlds of miscreants, shift workers and transgressors, but the city at night actually offers so much more. It should not be associated with darkness and fear, but rather free our minds, offer contemplation, silence and concealment in a situation where our attention and actions are increasingly controlled in the urban space. This book explores the rich potential of the dark city for our perceptual world. As Dunn asks, perhaps the question may no longer be about what spaces we wish to engage with but when we do?
