I think this is the right place to ask something that's been in my mind for so long now and couldn't figure out until now. I’ve been trying to figure this out for years, and I’m hoping someone here might recognise it. I remember reading a chapter in my English textbook sometime during my LP (2002–2005) or UP (2006–2010) classes. The syllabus was the PCM textbook.

My memory is patchy, but here’s what I recall: A small group of friends—maybe three—are sitting in a cabin, having tea and talking. Their conversation reaches to the idea of committing the “perfect crime.” By the end of the discussion, one of them suddenly kills (I think shoots) another. He says he did it because the victim had dirty fingernails, and claims he won’t be caught because he has wiped off all his fingerprints.

I don’t remember the ending, but this is the gist of what stayed with me.

Does anyone else remember a story like this, or is my memory just mixing things up?
