Trehan starts from the premise that the nature of crime today is transnational and has become more so with the unprecedented development of information technology. The book examines various criminal activities that are used to make huge sums of money and then goes on to examine the methods of money laundering which are used todestroy or hide its illegal sources. The author also analyses how illegally earned money is used after laundering for legitimate businesses and how money laundering affects national security and even the process of economic liberalization. The book includes a discussion of legislative and otherresponses aimed at countering the dangers of crime and money laundering.
