It took me over a year to finish this book, checking it out every so often. I have a little reminder in my Habitica glaring at me as if to say: Why haven't you finished this!? So after my wedding I took a deep breath, swore to myself I'd bull through it, and I did.
I kinda wish I hadn't.
I loved Colin Wilson when I was younger, and by all rights that should have meant I'd like this. Like not being able to go home again, though, I think I was better off not trying to read Wilson as an adult. He is completely and utterly fixated on the idea that sexual serial killers are a sign of humanity reaching a certain level on the Maslow Hierarchy of Needs - we don't need to worry about subsistence so much, so we act out in sexual ways. Before that time, all serial murders were for profit or survival in some way
I'm not convinced. Wilson ignores the probability that sexual serial killers existed before the early 19th century (except for token nods to Gilles de Rais and good ol' Countess Liz). He doesn't seem to even give any thought to the idea that documentation of such things might be lacking - perhaps because that would mean his thesis is incorrect. He doesn't even look at other cultures, like the eastern Asian societies, to see what might have been going on there. For Wilson, as with so many others, it goes back to Jack the Ripper.
But absence of evidence is not evidence of absence. I can think of many reasons that the few literate people in medieval Europe and earlier would have decided not to record stories of sexual criminals, even assuming that they were defined as such by the ethics of the day - after all, upper-class women had few rights, and lower-class people were out of luck entirely. Who's to say that a citizen of Athens who was assumed to have been set upon by "Maenads" and torn limb from limb was not the victim of a sex crime by our standards?
I don't think Wilson supports his thesis well, but the array of killers he talks about is encyclopedic. To me, the value of this book is in stories to research further if that's your thing. For that, he gets three stars. Honestly, though, it wasn't a fantastic read. I'm glad I'm done.
