1 ESO. Boy With The Dark Secret (Tapa blanda)

There's a new boy at school called Mats and he's from Sweden. Mats is very clever and speaks perfect English. He seems nice, but looks sad. He won´t join the kids for ice cream after school. He won't come to their houses or invite anybody home. A big black car arrives every day at exactly 4.05 pm to take him home from school and Mats never seems happy to get into it. What's going on? What dark secret is he keeping? And who can help him?.
