Matthew is 12 and he is afraid of germs.
This condition is triggered by the death of his baby brother who he didn't got the chance to meet in real life. He just know that his baby brother died and he thought it is his fault.
So he tried to stay away from germs by being careful and clean. Also his need of staying away from germs make him stay home a lot and he was afraid to go to school.
He watched his neighbors through the windows. He recorded what he saw in his notebooks.
A toddler went missing and right before he was missed, Matthew was watching him through the window.
Melody is a strange girl who wants to be Matthew's friend. They communicate via email. Now that the toddler Teddy is missing, and Matthew is house-bound. Melody is going to be his sick-kick investigator.
Things got more interesting. There is also a bully called Jake who was Matthew's friend.
The missing Toddler Teddy and the three young friends are going to solve this.
The story is exceptionally touching. It is wonderful.
Highly recommended it.
