At what point does following a person, or trying to intimidate him or her into accepting one's advances, become ""stalking""? How is stalking related to gender? Who is the stalker? What are the long-term effects of stalking? These are among the many issues explored in this groundbreaking empirical investigation. This book based on two special issues of the journal ""Violence & Victims"" presents in-depth findings on both victim and perpetrator, and includes a new understanding of the categories of stalking behavior: simple obsessional, love obsessional, and erotomaniac.
