Legal geography investigates the co-constitutive relationship of people, place and law. This essay provides an overview of how the law and geography cross-disciplinary project emerged from a context of mutual curiosity and explores how legal practice, in all its discretionary and rule-bound variety, co-produces places through an attentiveness to, and sometimes an apparent dismissal of, spatiality. The essay notes the formative importance of studies on power and inequality within urban governance in this predominantly critical field. However, it also considers how the cross-discipline is increasingly embracing legal geographic scholarship from within cultural, material and post-human geographies. Adopting the metaphor of the 'spatial detective', the essay situates legal geography as a way of examining law's materialisation within space, considering the field's methods, core concepts and the potential directions in which they may evolve.In this article, we outline the trajectory of the cross-disciplinary endeavour that has come to be known as legal geography. We suggest that there is much to learn by both legal scholars and geographers becoming 'spatial detectives' -of learning, Sherlock Holmes-like, to search out the presence and absence of spatialities in legal practice and of law's traces and effects embedded within places. In doing so, our aim is to think broadly about legal geography and of the critical and other drivers of its detective work. By using the metaphor of becoming a detective, we aim to illustrate legal geography's emphasis on law's 'worlding' and on it, being both active and still, vocal and silent. To do this, we start at the scene of legal geography's emergence, and of an apparent discovery by scholars, of something chilling within the body of the law.
