In "Battle Ground", Dresden assigns Murphy to guard the inhabitants of Mac's bar during Ethniu's and the Fomor's assault on Chicago. However, Murphy refuses to remain at the bar and goes to help Dresden save as many people as possible. She heroically kills a Jotun giant with a rocket launcher just before the giant can kill Harry, but then is accidentally shot and killed by a panicked Detective Rudolph moments later. At the end of the book, Gard confirms that Murphy will one day reincarnate into an Einherjar, but that will not be until the memory of her fades from the minds of those who knew her.
