Sidney felt an overwhelming rush of terror and adrenaline and she let out a blood-curdling scream as Billy doubled over, the knife slashing into him again.
She felt flecks of blood hit her, spraying all over the front of her jacket, and she threw her hands to her mouth, recoiling with horror.
The killer spun Billy around, streaks of scarlet painting his chest, blood dribbling from the corner of his chin, presenting the horrible sight to Sidney like a sick piece of artwork.
"Billy!" she screamed, tears falling down her face, reaching out to him.
Billy's eyes stared into Sidney's with urgency as if he was telling her to run, and he reached his hand out to meet hers.
The killer tossed Billy's limp body to the side like a ragdoll, and turned to face her, wiping the blood off the eight-inch hunting knife in his right hand.
A second, even stronger surge of terror trip-hammered through Sidney's system as she backed away in fear, slamming back into the balcony doors and furiously trying the handle to discover they were locked.
There was no escape. She was trapped. She couldn't tear her eyes away from the ghostly white mask and the blade advancing towards her.
Her hands scrabbled for a weapon, finding the lamp on the dresser beside her, and she hurled it at him.
The killer dove to the side to avoid the lamp; it missed, shattering against the wall beside him.
The lamp gave Sidney just enough of an opportunity to make a flying leap over the bed and tear out the door like a rocket.
"Help me!" she screamed, flying down the hallway, not turning around to see if he was following.
The maze of hallways seemed endless, but she finally reached the stairs, racing down them two at a time towards the front door.
And then, she screamed from the bottom of her soul as she saw the killer come barreling out of the kitchen, and up the stairs towards her from the direction she was running.
Sidney backpedaled away, made a U-turn, and ran back up the stairs, feeling his knife slashing at her back.
She bolted inside the first room, slamming the door in the killer's face, sending him crashing to the floor.
Sidney found the lock, and bolted the door shut, finding herself in another bedroom.
What the fuck was she going to do?
No time for thinking, she urged herself, and ran through another door into an adjoining bedroom, slamming the door shut and heaving a dresser in front of the door as a barricade.
Could she hide? No. Fuck that. She had to get the hell out of this house and find Dewey. Where had everyone at the party gone? Where was Tatum?
She had to stop thinking and act fast. She could hear the killer smashing things in anger, searching for her in the adjacent bedroom.
But there was no way out of this room. No other doors or windows.
But there was a panel in the ceiling above the bed; a long drawstring was attached.
It must be the attic.
And it was her only escape.
Sidney jumped on top of the bed and pulled the drawstring. The panel fell open, and a ladder extended down.
Sidney scrambled up the ladder into the attic just as she heard the killer throw his shoulder into the bedroom door.
She scanned her surroundings.
