The study examines the range of crimes in which solicitors become involved as primary offenders (mainly fraud) or on behalf of others (criminal planning and money laundering) and critically reviews the factors in their personal and working environment that may promote or inhibit such crimes and the ways that criminologists and socio-legal scholars have accounted for deviance and the regulation of the profession. It ends by discussing trends in contemporary lawyering and its regulation—ethics, discipline, ownership and surveillance—that could plausibly affect rates of crime by solicitors, focusing on England and Wales but also giving some comparative context with the United States.
