You get out of the car and sneak around to the backside of the house. Her family unusually leaves the backdoor unlocked, and as fate would have it, it is. Even though you had just used the wand to turn yourself invisible, you still take great care to make sure the door is silent. No need to freak them out. With care fit for defusing a bomb you shut the door behind you and begin your search for Stephanie, Lindsey's sister.

With that, you go silent. She can't see you so she assumes you left. Her face take on a look of deep thought as she considers your dark offer. A few times she even makes her way to the door before turning around. In the end though, she decides...
