In Norse mythology, Valkyries are warrior maidens who serve Odin, the chief god. Their primary role is to choose those who may die and those who may live in battles, guiding the souls of fallen warriors to Valhalla, Odin's hall, where they prepare for Ragnarok. Valkyries are often depicted as noble and fierce figures, embodying the ideals of honor and bravery in combat. They also sometimes serve as lovers or companions to the heroes they select.

If you're reffering to the movie Valkryie than it is about a true assassination against Hitler with a bomb but it failed
As Valkyrie is young, she can practice more than one 'strain' of magic. This means that she can be a Necromancer and an ELemental, at the same time!
in dark days she takes up necromancy, but we dont find out wether she takes it or not. i think we find out in death bringer or the 7th book.
You can only really see that he likes her in skullduggery pleasant 4, dark days. He might of like Valkyrie in Skullduggery Pleasant 3, the faceless ones, but you don't see it. In number 4 you can actually see written on page 398 in Dark days that Valkyrie trys to kiss him, but fails miserably. Also on the bottom of page 404 in Dark days again, the book says: "I'm with fletcher," valkyrie said quickly. Skullduggery turned his hear to her and didn't say anything. "We're together, kind of a boyfriend/girlfriend thing,". This is true, and I'm not making it up, by the way. It's a good series, and anyone who hasn't got it should buy it.
