Andrew, Duffy, Marie, Aunt Elise, and Andrew's mom are going on a walk in the woods.
After that, they arrive at the house they are staying at. A friend told Aunt Elise that they could borrow it.
What was that?!?!?!?
They quickly found out that the house was a mess! To make things even worse, Andrew found a creepy note written on the wall.
Beware the Sentinel
You forgot your jacket, stupid.
Their moms left to get groceries. Shortly after, the three kids heard a scratch on the door.
They quickly found out that it was the sentinel! He was like a giant bloodhound, and could track them within seconds. Where ever they ran too, the giant sentinel followed. He even knocked down the door!
To their surprise, the sentinel was just trying to return a jacket that Duffy had left in the woods!
