What are you doing in here with my daughter?' / Marty looked around the room, as if an explanation might be hiding somewhere. / 'Nothing!' he insisted hastily. 'It's all a mistake! I'm in the wrong house!' / The younger brother jumped up and down. He was really getting into this. / 'Whoop him, Dad!' he yelled happily. 'He's lying!' / 'Shut up, Harold,' his father told him. He looked past Marty at his daughter. 'Loretta, did he touch you?' / The girl nodded her head vigorously. / 'He jumped on me!' / He did not, Marty thought! He more like — fell on her. But how could he explain that? "
