I became aware of a bizarre fixation when the Netflix series Dark Tourist visited Milwaukee, former stalking ground of Jeffrey Dahmer who tortured, murdered, dismembered and even ate at least 17 men and boys. By far the majority of those who pay to join the ghoulish city tours commemorating his life and work were attractive, single women of marriageable age, who seemed somehow to consider him the ultimate dreamy life partner they would just love to have reformed – if only he hadn’t been bludgeoned to death in prison while serving 16 consecutive life terms.

Now Netflix has turned its attention to another serial-killing supervillain Ted Bundy. Recently it paid $9 million for a biopic called Extremely Wicked, Shockingly Vile and Evil, with Zac Efron (formerly the pre-teen heartthrob lead in High School Musical) as Bundy. Meanwhile, it’s whetting all those girl viewers’ appetites with a four-part documentary seriesConversations with a Killer: the Ted Bundy Tapes.

They’re not really ‘Conversations’. More rambling, evasive monologues taken from over 100 hours of recordings made (while he was on death row)  by a journalist who was writing his biography. Bundy refuses, throughout, to own any of the horrible murders he has committed. He only hints at complicity when the journalist invites him to imagine the thought processes which might have gone through the head of the putative murderer. Bundy does not find this difficult…

I’ve seen reviewers complain that the series – a mix of contemporary news footage and interviews with those who knew him – tells us nothing new about Bundy. But that presupposes you’re already familiar with his myriad crimes, which many viewers won’t be. Between 1974 and 1978, on a killing spree spanning much of the US, he murdered at least 30 young women (the youngest was 12), with a brazenness with almost defies belief. On one occasion, while on the run from prison, he snuck into the dormitory of a sorority house in Tallahassee, Florida, sexually assaulted and bludgeoned four sleeping girls (killing two), before breaking into another apartment eight blocks away and brutally attacking another girl there.

It seems inconceivable that he would have got away with it in our age of computers and video surveillance. But this was the 1970s and Bundy – a smart, cunning, plausible law student who was working as assistant director of the Seattle Crime Prevention Advisory Commission (where he wrote a pamphlet for women on rape prevention) when he committed his first murder – knew just how to beat the system. Later he boasted how he’d used his training to leave minimal incriminating evidence at the murder scenes.

Bundy’s crimes were unspeakably grisly. Sometimes he would even revisit his dead victims in order to have sex with their rotting corpses. Yet in person, he was good-looking, normal-behaving and could be disarmingly charming (which was how, of course, he managed to lure some of those girls to their deaths: he certainly didn’t look like a serial killer).

His murder trial (extensively filmed by a huge media circus) in Florida attracted numerous young women, at once entranced and appalled by this handsome fellow cracking jokes with the judge. It’s a fascinating documentary, if you’ve a stomach for all that relentless killing and all that shouting you’ll do at the TV screen urging the police to do a better job sooner. At his execution, there were partying scenes outside the prison, which some commentators suggested were tasteless and unbecoming. After what this monster did to those poor women? Seems like a normal, rational response to me.
