"Matt DeLisi deserves kudos for putting together what is surely the most comprehensive, detailed, and up-to-date exploration of psychopathy available. The contributions reflect multiple and diverse perspectives on core issues ranging from etiology to assessment to antisocial conduct. The Routledge International Handbook of Psychopathy and Crime is a must-have for anyone whose research or practice touches on this perplexing disorder." - Professor Stephen D. Hart, ¿Department of Psychology, Simon Fraser University, Canada"The Routledge International Handbook of Psychopathy and Crime is a must-read edited volume for anyone seriously interested in understanding psychopathy. Professor DeLisi did the field a major service by putting together this much-needed collection of works written by the "Who’s Who" of psychopathy researchers. I know that I will be consulting this book for years to come in my own work and assigning it in my courses. Without a doubt, any serious psychopathy scholar will want to add this book to their collection." - Kevin M. Beaver, Judith Rich Harris Professor of Criminology, Florida State University, USA
