I had never killed anyone before, but I didn’t even think about what I did next. I shoved Mitch’s face back into the snow, ignoring his muffled shouts and protests as he struggled for air. He was a big, strong guy but not bigger and stronger than me. There was a point when I could have stopped and let him go—no major harm done—but I wasn’t about to let him go back to Sadie after I had pissed him off like that.
