Unexpected and very good story. Matthew is 12 and is afraid of germs. What I don't expected is the start of a Rear Window type of story.
A toddler is missing and Matthew is the last person who saw the baby. So while the adults, parents, neighbors and police are all looking for the missing child, Matthew started his own investigation.
As he didn't want to leave the house, he has a side-kick, Melody.
Matthew suspected that it is a neighbors who had taken the child. And he is going to find out.
Once it turned into an investigation, it run really well.
