Hello @popmanj. You have a good plot here. Treachery always gets the reader's attention. As for the paragraphs, there really is no rule except for when someone new starts to speak or when the action changes (location) that's a good time for a paragraph. If you have any questions, I'd be glad to answer them.
Writing is great fun. I hope you continue to let your imagination play and to share what you imagine with the community.
Okay, thank you, noted
