'These are the corridors in which Earl Illingham would chase his beloved kids but now they are the barren passageways to hellish rooms.'

'This woman's great, isn't she?' Clara sarcastically bit. 'I can just see her working for Location, Location, Location.'

Walking down another corridor, a couple overtook Bucky and Clara meaning they were now at the back and Clara felt as if she was being followed. Looking behind her, she saw an empty dark corridor with a vase at the end. As she turned the corner, she failed to notice the silhouette watching her.

Bucky reached into his pocket and pulled out his particle communication device and activated it so Clara turned it off again, much to Bucky's disappointment.

'Put that thing away!'

'Clara,' Bucky adopted an alluring cheeky smirk. 'People will wonder what you're seeing.'

Jokingly punching his arm, Bucky giggled but Clara crossed her arms as they continued walking with the group.

'I'm serious,' the female snatched the device out of his bare hands. 'We're walking through air which has loads of particles so it'll go off every two seconds.'

'Actually it's designed to lock onto a change in particles. Fitz and Simmons said that in the presence of a figure or living being, the particles move more to allow space for the being to be there. This detects that change.'

The event manager opened a new door which lead to a staircase, elongating down into a pit of total blackness.

'These were the dungeons,' she led the group down into the unknown. 'Earl Illingham was extremely clear about those that crossed him. In fact, in one of his many autobiographies he said the following – 'Those who disobey or cross thee shall end up in the cages of despair. There they shall face punishment and devastation.'

'Lovely,' a man whispered to his wife.

Bucky heard his phone ping and ignored it when he saw something out of the corner of his eye. Screaming, he made most of the group jump and Clara asked him what was wrong. He pointed to the figure in one of the cells but the event manager laughed. Turning the torch on, she shined a light on the figure to reveal it was a plastic human-sized mannequin.

'Don't worry sir,' she snorted to herself. 'You're not the first person to scream at them.'

Continuing on with the tour, Clara laughed to herself and stared at an embarrassed Bucky. He went a little red and ushered her out of the dungeons just as another figure stepped out from the shadows.

Skimming through the book shelves, Clara pulled out a poetry book. Noticing a poem called 'Lights Out', she started reading it.

You hear it sometimes, don't you?

You tell yourself you're wrong

That there's nothing there at all

But you always hear its song

The darkness sometimes waits for you

It waits sat on your bed

Sometimes it chooses to follow thee

And waits inside your head

'OK,' Clara placed the book next to her and crawled into her sleeping back. 'That's quite enough of that.'

'Goodnight,' the event manager said to everyone as they bedded down in the main hall. 'Sleep tight and don't let the ghosties bite.'

As she flicked the main light off, Clara placed her head on the pillow she brought with her. Staring at the ceiling, she noticed the large silver chandelier. Surprisingly, it seemed as if it was swinging a little. Shaken, she turned on her side where she tried to drift off but it wasn't easy.

Bucky Barnes was awoken by a shoulder shake. Opening his eyes, she saw Clara crouched over him. Asking her what she was doing, he remembered where he was.

'Bucky,' she quietly admitted. 'I need the toilet but I am not walking through that corridor on my own.'

'Clara,' he sat up and rubbed his eyes. 'You're 28. The Bogeyman isn't going to snatch you.'

She folded her arms and so Bucky pulled the sleeping bag duvet off of him and stood up.

'Come on then,' he helped her off of the floor. 'If a ghost comes I'll save you.'

Opening the door to the corridor by the main hall, Clara spotted the toilet door at the end of it. However it seemed like it was miles away. Darkness spilled out onto the passageway and then Bucky tried to find the light switch but he couldn't.

'Go on then.'

'Come with me.'

'Oh for heaven's sake,' he rolled his eyes unintentionally.

As they began walking down the corridor, the silence screamed at the pair. Bucky started feeling a little nervous as they left the safety and security of the group who were all asleep.

'Don't you find it weird?' she said to Bucky. 'This house used to have so much history and now it's the focus point of some money-grabbing company.'

'My feet are freezing,' Bucky moaned.

'Well you're the one that decided to walk down a laminated corridor with bare feet.'

Suddenly, Clara noticed the particle communication device in Bucky's pocket. She questioned him about it and he said he didn't know he had it in there.

Without warning, Clara shrieked and stopped her boyfriend in his path. When he realised why she stopped, his heart stopped beating. There, in front of them stood a figure in the darkness, guarding the toilet door. Only its outline was visible and Bucky hesitantly and slowly held the device up.

'Don't run,' the device said in an almost screeching tone. 'Please. Don't run.'

'What… what are you?' Bucky was too scared to even move never mind run.

'I am the darkness. I can never find my brothers and sisters.'

'Hang on,' Bucky began breathing heavily as Clara held onto him tight. 'The particles are reacting. The particles… the particles are alive and conscious.'

'I don't know what my brothers and sisters look like. I'm lonely. We're all lonely. We never see our brothers and sisters.'

'If the particles are living why do they take on the form of human figures?' Clara bravely managed to ask.

'Humans will only talk to humans. They never hear me when I'm just particles floating in the air. They never see me. When I take human form I want them to recognise and speak to me but they run and hide. I'm so lonely.'

'Right,' Bucky tried to process this. 'The particles in the darkness are alive and conscious. There are millions of particles around you so why can't you see them?'

'We never see one another. One particle can create human form if it's lonely enough. They're all around me but I can never see them.'

The device began screeching loudly and then sparks flew out of the device. Dropping it, Bucky and Clara watched as the figure decayed into nothingness.
