@ElizabethBest I haven't seen the film you mentioned about castrati, will track it down, thanks.
Nowadays it's easy to self publish stuff, I've published a couple of things through Lulu and was impressed with the quality. Then you can pay to get a thingy number and also sell them on Amazon if you like (I didn't do that but have a friend who did.) There's no initial outlay for Lulu.
If we're talking grizzly stuff, it haunts me about Captain Oates. I mean, his last line was haunting. And his fellow climbers must've known he wasn't coming back, I suppose. I decided on that. Before that I used to imagine what it'd been like for them to eventually decide to leave without him. 😧I could've just looked that up apparently, that they knew, but it was so gory I didn't want to know any more about it.
Of course, a lot of people are fascinated by anything WW2 , holocaust, nazis, hitler etc. It is fascinating as it's so relatively near us in time but so different and gruesome. My dad will read or watch anything about that.
