One type of TV show that I enjoy are detective murder mysteries. I don't watch them all - that would be nearly impossible, Netflix carries so many - but I'm always looking for detective shows that I find absorbing. "Inspector Lewis" is probably my favourite. I loved "Prime Suspect", Helen Mirren's tour de force. I'm in the middle of "Wallander", recommended by a few wmtc readers, although I'm watching the BBC version with Kenneth Branagh, not the original Swedish show. "Case Histories", featuring Jason Isaacs as private investigator Jackson Brodie, is another one I enjoy. And I've sampled many more - Inspector Morse, Midsomer Murders, Cadfael, and so on. On my to-watch list are The Killing and The Fall.
As much as I enjoy this genre, I often end up annoyed when we learn "whodunit". Because, too often, you know who done it? A woman.
Sometimes, the murdering woman turns out to be trans* or bisexual. TV trans* and/or bisexual murderers practically constitute a separate subgenre. The contemporary version doesn't portray these women as insane by definition, merely driven insane by society's intolerance and by the men who wouldn't love them.
I haven't quantified my observation (yet), but I'd estimate that on the small screen, murders are committed by women about 60 or 70% of the time.
In reality, in the US, for example, men commit around 85% of all homicides. About 15% of homicides in the US are committed by women.
(I note that "Prime Suspect", with its more realistic plot lines, is not included in this.)
This disconnect between reality and fiction - the topsy-turvy world where women are more likely to be murderers than men - is not a new or original observation. When the movie "Fatal Attraction" came out in 1987, there was a spate of commentary saying essentially the same thing. If the plot of that movie had been a real-life scenario, Michael Douglas's character would have been terrorizing the family, not Glenn Close's. A few years later, the same arguments cropped up in relation to "Basic Instinct" (1990), with the addition of the crazy bisexual motif.
As a writer, I understand why TV murder-mystery writers and producers might reach too often for the female murderer. It's unexpected. It's different. It's interesting precisely because it's not real life. Let's lead the audience to suspect the controlling ex-husband, then let's surprise them with his female victim who couldn't take it anymore.
But as a feminist and a media-watcher, I find it highly irritating, and potentially harmful. An ignorant viewer could easily come away with the impression that women are far more dangerous than men. Might that make it more difficult to believe - and to have compassion and empathy for - the dangers that so many women face from their partners and ex-partners, even on a subliminal level? Could the TV unreality make it more difficult for people to understand and accept the real statistics on femicide?
Historically, there has been an abiding fascination with female murderers in all forms of fiction, from Medea and Lady Macbeth to Lizzie Borden and Aileen Wuornos. The interest in female killers - including real ones - may stem partly from their very novelty. Plus, the notion of a female murderer runs counter to most gender stereotypes. Women are supposed to be loving and nurturing; we are supposed to be weak, fearful, and squeamish. On the other hand, we're supposed to be unable to control our emotions. In real life, perhaps most murders are fueled by testosterone, but we've always got hysteria!*
I expected to find a spate of stories about the female murderer in TV detective dramas, but to my surprise, I found none. Perhaps I missed them, or perhaps this theme is mostly explored in graduate school papers like this one. I did find numerous stories about the negative portrayals of LGBT people, especially trans* people, a topic much more in the media spotlight right now than garden-variety sexism. (I also found the fascinating rabbit-hole called TV Tropes, which looks like a genre-writer's dream.)
As I said, for now this is based only on observation. I haven't quantified it yet, haven't sat down and counted what percentage of TV detective-mystery episodes end with a female murderer. But I might, eventually.
