Harry kills a Black Court vampire with a laser-guided frozen turkey dropped from an airplane passing overhead. Sure, it was someone else's curse that Harry redirected, but the end result had even the other blampires going WTF.
"For my next trick," I panted into the startled silence, "anvils."
Murphy refusing to break under the White King's mind control. Granted, that doesn't seem like much in this series, but not even Lara managed to do that before Harry told her that her dad was powerless.
Doubles up: Harry, who had no reason to believe Murphy hadn't started to break and was really, truly, out of it, only needed two words to be bet-his-life certain.
"Leave me alone, Mister Dresden."
Awesome moment for Jim Butcher: Blood Rites has two of the best opening and closing lines in all of fiction. Opening: "The building was on fire, and it wasn't my fault." Closing: "'Hey. Why did you get large breed puppy chow?'"
Harry and Murphy, with a little magical help, motorcycle-joust a car loaded with Lord Raith's goons and send the car hurtling away on fire.
The climax, where Harry tricks Lord Raith into revealing his weakness—namely, his inability to feed due to Margaret Dresden's death curse—with Lara Raith as a witness, thereby allowing her to take over in a coup d'etat. Even Lara, no slouch at political intrigue herself, is impressed. Harry might not resort to subtlety often, but when he does he is good at it.
Lara Raith:You've made me the cat's-paw for you, Dresden. While making me think I had the advantage of you. You've played me at my own game, and ably. I thought you capable of nothing but overt action. Clearly I underestimated you. Harry: Don't feel bad. I mean, I look so stupid.
Which is also a lovely call back to Summer Knight:
Lloyd Slate: Spooky. He doesn't look all that smart.
Harry, Murphy, and Kincaid's assault on Mavra's base, with the likes of Kincaid's impressive moves with his spear-slash-shotgun, Harry holding on to his shield despite his hand being burned away, and Harry and Murphy using the vampires' own land mine against them. And all without any of the children they saved getting hurt.
The next book reveals that it was simultaneously a villainous example for Mavra herself, as she'd not only survived, but staged it all in order to collect blackmail material on Murphy.
