The children are exploring around the cabin. The cabin hasn't been used in a while so it is dirty inside. They aren't very enthused that it is so dirty inside.
When the children were cleaning up a room to sleep in Andrew had found a sign on the wall. The sign had read, " Beware of the sentinel." This had scared Andrew and Duffy, and Andrew's mom said to stop scaring Marie.
The children had went on a hike on a trail into the woods. Andrew had a feeling that someone was following them throughout the hike. Duffy had left his jacket behind on the trail when they went back to the cabin.
Beware of the Sentinel
The children's parents had gone to the store leaving them in the cabin alone. The children were playing monopoly together when they started hearing scratching at the door. This scratching had scared the children.
The children had walked towards the door in fear. Duffy looked through a window to see what was out there. He couldn't figure out what it was but the children thought it was a type of bloodhound that had smelt Duffy's jacket and scented them.
The creature had been a sentinel and had caught the children in a room of the upstairs of the cabin. The sentinel had said that they found the jacket and was returning it to the children.
