Wendy quickly ran to the left door.
Even with bound hands, she could open the door.
After she entered the room, the door closed again.
And could no longer open.
"no turning back ..."
Before her, Wendy could see several cobwebs and spiders.
In the center of the room was a large spider.
The spiders were busy with another victim.
Wendy had somehow fight through the space, or sneak by the spiders.
