The mamba hissed and raised its head even higher.
Lara slowly, ever so slowly, began crouching down. The snake’s head lowered as it kept its eyes level with hers. When she felt she could reach her boot without any awkward motions, she moved her right hand down and slowly, gently pulled out the Scalpel of Isis.
She straightened up, and again the mamba raised its head. The snake was no more than two feet from her, within easy striking distance.
But I’m within easy striking distance of you, too, she thought.
She reached her left hand out very slowly. The snake watched it, unblinking. There was a box of tissues on the sink. Ever so carefully she pulled one out of the box and slowly moved it toward the mamba until it hissed again.
Then, tensing, she dropped the tissue. It fluttered toward the floor, and the mamba struck—and as its deadly fangs went through the tissue, she grabbed it just behind its head with her left hand and stuck the dagger up through its underjaw with all her strength. The blade went up through the mamba’s tongue and out the top of its mouth, pinning its jaws shut.
It began struggling in her grip, but it was unable to sink its fangs into her. She brought the snake’s head down again and again against the hard enamel edge of the sink. At some point she realized that it was dead, had been dead for a few moments and was simply jerking spasmodically. She walked to the door of the cottage, pulled the Scalpel of Isis out, and tossed the dead mamba onto the stone patio.
