In , Stephanie Swales provides a close reading (a qualitative hermeneutic reading) of what Lacan said about perversion and its substructures (i.e., fetishism, voyeurism, exhibitionism, sadism, and masochism). Lacanian theory is carefully explained in accessible language, and perversion is elucidated in terms of its etiology, characteristics, symptoms, and fundamental fantasy. Referring to sex offenders as a sample, she offers clinicians a guide to making differential diagnoses between psychotic, neurotic, and perverse patients, and provides a treatment model for working with perversion versus neurosis. Two detailed qualitative clinical case studies are presented—one of a neurotic sex offender and the other of a perverse sex offender—highlighting crucial differences in the transference relation and subsequent treatment recommendations for both forensic and private practice contexts. offers a fresh psychoanalytic approach to the subject and will be of great interest to scholars and clinicians in the fields of psychoanalysis, psychology, forensic science, cultural studies, and philosophy.
