Justin has been missing for two weeks now. I miss him a lot.  61  I’m worried that something bad has happened to him. I’m sure he came home that night at around 11p.m. 62 我听见他放自己最喜欢的CD。I wonder where the aliens with large black eyes have taken him.

Mavis told me that creatures from outer space took her away a few years ago. They did some  research on her. 63  The whole experience was very frightening, just like a nightmare, but at least they returned her home. I hope they will return Justin soon.

64 警察没有取得多大进展。Now they are searching for other witnesses. They say Justin might have been murdered. Dad is very disappointed with them. He thinks they are not doing their job properly. Mum is really worried, too. She can’t sleep well.  65  I hope Justin will come home soon and tell us what happened to him. I want all of us to be together again.
