I place my bets on it being either the Winchester Mad Bombings or the Detective War, they are the only areas of the past that haven't been covered in detail, unlike LABB were the story is like 100% known.
wait wait i know what the detective war is (and hell yeah I’LL TAKE ANYTHING L-RELATED PLS AND THANKS) but what are the winchester mad bombings and where are they mentioned
i’m a bad fan omg why don’t i know these things?
(Edited this a bit.)
This one too! I’m overactive on Tumblr this afternoon I guess?
Both of these were in Another Note. The Winchester Mad Bombings were the case that 8-year-old L stuck his nose into in such a way that he got Quillsh Wammy’s attention.
These would have taken place around 1987-1988 (depending on the time of year), so my personal assumption related to them has always been that they could have been suspected IRA bombings in and around Winchester, which is a “charming country town” sort of place. IRA bombings were still a present fear in England at that time, and it would be interesting if something that initially looked like them turned out not to be.
Someone else mentioned that the Winchester Mad Bomber gets a mention in the LCTW tie-in novel, but that’s not where the idea originated. The mention is a nod to Another Note. That particular novelization is weird because it’s definitely not canon to the main DN universe (it’s like the writer never read a single thing Ohba said about L and had the most fanon interpretation possible), and it’s not quite a faithful representation of the plot of the movie, but the writer still made a point of tying it in to both the movieverse and Another Note (while Another Note itself is mangaverse). The LCTW novelization is like an AU unto itself.
There’s a lot of minutiae in Another Note that tends to fall by the wayside because it’s in the form of super offhand comments in the text — not part of the main action at all.
