<p>This richly detailed study examines the English criminal trial and the nature and scope of the most prevalent felonies during the period c. 1300-1550. There is particular emphasis on the accusation process (studied in depth here for the first time, showing how it was, in effect, a trial within a trial); the discovery of a veritable revolution in conviction rates between the early fifteenth century and the later sixteenth (why this revolution occurred is explained in detail); the nature and scope of the most prevalent types of felony in the period; and the startling contrast between the conviction rate and the frequency of actual punishment.
