Marcus Felson has been a leader in crime theory and crime science, and his name has become synonymous with routine activity theory. This volume provides a rich collection of essays that honour the work of Marcus Felson, acknowledging his pioneering work whilst also making a substantive original contribution to the field. Bringing together some of the foremost thinkers in criminology today, alongside former students of Felson and those most influenced by his work, the contributors explain and apply the work of Marcus Felson in the fields of criminal investigations, the crime drop, crime analysis, criminological theory, transnational crime, violence, burglary, vehicle theft, and offender typologies. The breadth of these topics highlights the impact that Marcus Felson has had on the field of environmental criminology and criminology more widely. This original volume of thought-provoking readings will be relevant to all scholars, researchers and practitioners of Criminology and Crime Science.
