Our present system of criminal prosecution originated in England in the sixteenth century. Langbein traces its development, which was at its most intense during the reign of Queen Mary. He shows how the common law developed a system of official investigation and prosecution that incorporated the medieval institution of the jury trial. He places equal emphasis on the role of the justices of the peace as public prosecutors. The second half of the book compares the English system with those of the Holy Roman Empire (Germany) and France. He concludes by refuting the popular opinion that the English were strongly indebted to continental models. "This is an excellent work of scholarship, exhibiting wide research, erudition and analytical ability." --Joseph H.
