Mira

"First, delay the greeting ceremony," I said. We're going to be ass deep in vampires; there won't be time for anything else tonight."
Verne nodded. "Done."
"And I want Mira's head in a basket," I said.

(Blue Moon, page 146, paragraph 3)

* Because she was scorned by Richard, Mira lured Nathaniel into a D & S tryst. With him tied up, she then gave him over to Colin and his rotting vampires so that he could be used as a "message" for Anita.

* Because of what Mira had done, Verne was going to give Anita whatever she wanted to make it right between their clans again. Anita wanted a delay of the vampire meeting and Mira's head in a basket, although the later was meant to be a figure of speech. Verne complied to the letter of the request, and Mira was killed.
