My final part in the murder poem set, could you comment please?

This reminds me of an Agatha Christie whodunnit in verse and sets the mood, reminiscent of some of her books and plays I have seen. A touch of luxury, silk pyjamas etc. Don't know anyone who wears silk pyjamas nowadays, very popular back then. I enjoyed your triology. I think that you need to rewrite your final couplet in my opinion. It could do with a stronger ending.
