This edition of the correspondence between A. V. Dicey and A. B. Keith is of interest to scholars of imperial history and the law, especially the field of conflict of laws. It presents the exchange of views between Dicey, the older professor, and Keith, the young man at the the Colonial Office, on a multitude of topics of contemporary importance. It provides an insight into the books and revisions of earlier editions written by both men. The period 1905-1919 was filled with political and constitutional issues that drew the attention of public-minded individuals. Such specific discussions of constitutional matters over time was rare in Edwardian Britain, so this collection of letters presents an important addition to the stock of private materials by which public policy must be judged.
