Read this story a long time ago. Not sure if here or elsewhere. Stalker kidnaps young women from her Denver (?) apartment and takes her to an abandoned mansion in old lumber/mining town in mountains. Brainwashes her to be his lover. Later might kidnap her younger sister. Later still finds 3 or 4 coeds who's car is stuck in snow after getting lost on ski trip. Ends up converting most or all to his domination.
