Grabs Hecate's head

Thorne had plunged my favourite dagger into Hecate’s heart. She then twisted it three times, as I’d instructed. By then I was at her side; I seized Hecate by her long hair and bashed her head as hard as I could against the edge of the iron cauldron. I had hoped that it might crack like an egg, but to my disappointment it remained intact and I feared that the struggle would be difficult and prolonged.

And so it proved. It would not be easy to slay the Queen of the Witches.
