The appearance of this excellent treatise is a major step toward a better understanding of the place of restitution in Anglo-American law. The authors\u27 exhaustive treatment of the English case law and the inclusion of much American authority give a perspective on the field which has not previously been available. Like the 1937 Restatement of Restitution, this is a presentation in one volume of legal and equitable remedies for enforcing a substantive right to restitution.\u27 It goes well beyond the uneasy, loose association of the legal and equitable parts of the Restdtement, however, and gives us a unified treatise. Until we have a similar treatment of American law, this book will certainly be a major research tool for American lawyers
