From Protector of the Grey House:
Natalia swung the small extinguisher over her shoulder, holding it with her right hand while her left went to her side. She was leaning into her left leg, her feet shoulder width apart, ten feet from Alexandra. She stared at the kneeling mass of charred vampire, a slight smirk on her face. The room was so quiet she could hear Alexandra’s skin crackling. She waited, and watched as more and more of the creature’s skin healed, knowing the woman was still capable of hurting her. Seconds later, Alexandra moved toward her. Natalia swung the extinguisher and connected with Alexandra’s head when the woman was two feet from her reach. The solid TANG! of extinguisher hitting skull echoed in the high ceiling room and Alexandra went sprawling. The side of her head was sunken in, but she was still healing herself.
Natalia, tired of waiting for the vampire to turn to dust, stepped forward swiftly, swung her weapon around and brought the flat bottom down hard. The unyielding metal slammed into the vampire’s head, crushing bone and brain. It was finally enough. Alexandra tried once more to heal the damage and failed, turning to dust with one final wordless sound. Natalia looked up and caught Vincent’s eye, then glanced around the room. She stood tall and left the extinguisher on the ground.
