Before watching the movie:
I’ve had this physically on my shelf (or thereabouts) for over a year, and it’s high time I got to it. A classic, obviously. The evocative title is frequently referenced and parodied. But what is it? Nobody seems to go into that. There’s a telephone, and a murder, and that’s about it. The box says there’s a love triangle, and a murder arranged by telephone, but it’s still pretty vague. I expect somebody overheard on a party line, but otherwise, I’ve got nothing.
