Yesterday I went to a RNA meeting in Holborn, where the talk was by Elizabeth Hawksley (co-author of a book called 'Getting the Point'). It was all about punctuation in dialogue. There were a few readings where punctuation was missing and it sounded awful, and a few exercises of writing in punctuation. These came from the book. I learned a couple of things which I wasn't sure about. These were:
1. When a person has a lot of dialogue, say that goes into two paragraphs. You put one speech mark at the start of the first paragraph, one at the start of the second paragraph and one at the end of that paragraph.
2. When you have a quote at the end of the sentence (like the sentence in brackets above) you put the full stop after the speech mark. This has been something I've not been sure about recently, and now I know.
I found it an interesting talk. It reminded me that I don't know everything, and I needed to get out the book after all, which was in my spare wardrobe. This I did this morning, and is now with a few more reference books at the bottom of this computer desk.
So, if you're not sure about your grammar and punctuation, then buy the book.
