Nightfall

                                    

                                          
Two beady red eyes stared out from the window. Their source sat on a chest of drawers like a patient little predator, just watching his prey. Two hunters below it, on their car, loading guns of rock salt, silver and god knows what else. They really had no clue what it was that they were dealing with, did they? Well - anyways, they were going to be the ones to finally give him back his Tailypo. With this thought, the creature flicked its bloody stump of a tail against the cupboards in boredom. 'Give it back, give it back, give it back!' He whispered, quietly through the darkness, and then shirked away from vision like a hissing shadow. 
                          
Meanwhile, Dean was still sat there - having finished his pie and watched the sun go down. Sam was rooting around in the trunk (somehow failing to discover Crowley), and packing everything that he could find for dealing with with every monster that he could think of. Holy oil, for angels. Rosemary, for lamias. Silver, for wraiths, werewolves, and shapeshifters. The lore hadn't been helpful in providing any sort of idea about what this thing was, but it had provided a reason that it was here... 
Sam walked up to Dean, and placed his hand on his shoulder briefly to get his attention. 'Okay. I've got an idea as to why Tailypo's in this house. This was the place that he originally attacked. It was refurbished and renamed after the dude was killed in the 1920s.' 
'Hmm.' Dean replied, 'Any clue as to what it actually is? How to kill it?' 
Sam shook his head in annoyance. 
                          
'Okay. I feel safer already.' Dean smiled foolhardily, and walked straight up to the door of the house, holding an EMF meter. First, they needed to at least try to work out what they were dealing with. Sam caught up to him quickly, and pushed open the door with the barrel of his handgun. Taking a look around, Dean felt hairs on the back of his neck stand up, and Sam jumped backwards slightly as both brothers heard a massive crashing noise from upstairs. 
With its familiar, grating ring, the EMF meter started up. Sam twitched his head around, smelling a familiar scent. 'Ozone, Dean. It smells like a spirit.' He announced, and changed the bullets in his casket from silver to rock salt. 'But I thought that you said that it was an animal, with teeth and claws and stuff?' His brother replied in a hushed tone. 'Well, yeah - but who's to say that animals don't have ghosts?' 
                          
Sam had to stop himself from accidentally pressing the trigger with shock as a chest of drawers flew out from a darkened dining room and crashed against a wall. 'Where is it?' A cutting, almost serpentine voice slithered around the corner and flowed into the air all around them. It physically hurt their ears. 'Have you bought me my Tailypo?' The same voice continued, slowly morphing into more of a terrifying growling, than anything else. A shriek that sounded like a vixen rounded the corner following this, and the noise of smashing china echoed out across the house. 'Bloody hell.' Dean mumbled, and then moved towards the corner...
