International Law and the Investigation of Transnational Crimes constitutes a valuable and important contribution to the literature, one that challenges the field's traditional State-centric and treaty-centric orientation and redirects scholarly attention towards the informal, administrative, and private-sector mechanisms through which cross-border crime is actually investigated today. It will be of significant interest to scholars working in transnational criminal law, international human rights law, global administrative law, and data privacy, as well as to practitioners navigating the increasingly complex landscape of cross-border criminal investigation.
