BK posted about watching the 1964 film Shock Treatment, which I have just downloaded. Looking forward to sitting back and watching it later.
I discovered this one either through seeing a trailer back then, or in finding the movie tie-in paperback. I was crazy about those, and I scarfed up anything that looked interesting, especially thrillers.
What's insane is that, to this day, I have no idea whether it ever came around to where we were living, or if I ended up seeing it, or didn't see it. It's all a blank. I'm thrilled that this copy is up there, and l'll just have to see if any of it seems familiar to me.
