I was reading the mystery Have His Carcase by Dorothy Sayers this week, and in a list drawn up by the sleuths for 'Things to Be Noted' and 'Things to be Done', I kept running into the initials N.B.
Since N.B. always came toward the end of each note, setting off the last thing mentioned in each section, I thought at first that it was a variation on P.S., but after a while I decided that didn't work, so I abandoned the novel and went to my primary dictionary, which informs me that NB (the periods seem to have been dropped over the years) means "note well" and is derived from the Latin nota bene.
Ooh, this could be useful. I wonder why it's not in common use?
P.S. As far as the mystery goes, Have His Carcase is rather more gruesome, complicated, and clever than I wanted. Being by Sayers, it has a great deal of wit and substance, but it is decidedly more graphic in places than you might expect from a British mystery from 1932. Overall it's pretty good, and it places it heads toward brilliant, but it has a high enough "yuck" factor to take it off my "recommend it to everybody" list. If you like codes and ciphers, though, toward the end of the book it has some rather detailed lessons in making and breaking a certain type of cipher.
And, yes, Lord Peter Wimsey fans, this is one of those books starring that hero and Miss Vane, where he knows he's in love with her, but she isn't sure what she thinks about him.
Update: Hmmm. Now that I know about NB (or N.B.), I suppose it's going to pop up all over the place, and I'll feel silly for not knowing about it already. Exhibit A: see this multi-book book review post, specifically the review for Girls Gone Mild: Young Women Reclaim Self-Respect and Find It's Not Bad to Be Good by Wendy Shalit.
K-Drama Movie Review: Detective K: Secret Of Virtuous Widow - Detective K: Secret Of Virtuous Widow; a movie rather than a series. Features Kim Myung-Min (King of Dramas, Bad Family) as Detective K, a brilliant though...
