Feeling your heart pounding in your chest, the taste of copper in your mouth, you push through the forest, shoving twigs aside and ducking under branches. Grace's scream had been close, and now you can hear more: the sound of bodies thrashing and struggling against the grass. Grace's voice rises again, starting another shriek—
—which is cut off in a choking gasp.
You sprint forward, driving yourself through the thick foliage. Suddenly, up ahead, you can see a splash of color past the leaves, stumbling to a halt.
The headmaster is kneeling over Grace. His hands are wrapped around her throat, squeezing tight, his knuckles showing white through his skin.
You've got no time to think. You need to make a decision—now.
