Harry never saw it coming. Spoilers for SH3. (I make up the most imaginative titles ever.)
He'd tried to teach her how to use a gun, but she hated it, so he gave her a tazer instead. He'd signed her up for self defense classes. He'd taught her never to be afraid, that fear made you do stupid, messy things. And he taught her love, and respect, and told her he loved her, every single day. Every morning, every night, every phonecall. He had to make sure she knew, always, that she was his special little girl.
It took him hours to get the words right, to make the horror understandable. He sat down the moment she went out and wrote, and wrote, and then when he was finished, he sat in his favorite chair and he waited for the end.
Harry Mason never felt it coming, but he expected it anyway.
