The First Thing That Came To Mind
After installing the software that was provided with the baby monitor, both Heather and Adam immediately accessed a monitor on their respective cellphones to keep an eye on their child. Because of this, they were able to keep an eye on their child at all times. They were so concerned that there may be another person in the nursery with her that they used the remote camera controls to pan around the entire room. They were looking for anyone else who might be there.
They looked around to see whether there were any other people in the area. They received the feeling that at least one other person had been present in the nursery at the same time as she had been there. Is there a possibility that their daughter is, in fact, involved in some kind of precarious circumstance?
