The museum was absolutely crammed with tourists. Excited young children rushed past the humungous whale skeleton that had been hung on the orange wall, adults laughed at the stuffed bears in the Animal Kingdom section and tour guides rolled their eyes when yet another guest tripped over the wires leading out from the projector screen in the main hall. Popcorn had been introduced to the museum to attract tourists and it seemed to be working. More people flocked to the building than they had ever done before.

Bucky was stood beside the stuffed zebra in the fake jungle room with the cardboard popcorn box in hand. He didn't understand as to why the Zebra had been placed beside a polar bear. They don't even share a habitat. He was about to inform Clara of this mistake when he turned around and noticed that she was no longer there. Instead, she was halfway across the room reading information on illegal poaching. She could feel the sweat beginning to drench her red blouse and she blew onto her hair. Bucky's hand grabbed hold of her shoulder and she rotated to face him.

'It's too hot in here,' she protested against the heat, cheekily wiping a bit of sweat on Bucky's blue jumper. 'I don't know how you can wear that jumper.'

'I didn't know it was going to be this warm,' he wiped his brow. 'There's something called air-conditioning and I'm pretty sure this museum would do so much better with it.'

'I have to agree with you there, babe. Let's go and see what is in the other room. Quite frankly that massive stationery elephant terrifies me.'

Before Bucky could even say anything, Clara grabbed hold of his hand and pulled him past the still sloth on the artificial branch and into a very unusual corridor. After seeing the next room, the pair strolled in and realised it was a Mayan exhibit. Old stone vases were protected by thick glass and large paintings of Chechen Itza were hung on the dark walls.

'Eurgh,' winced Clara as she approached a six foot long coffin in the middle of the room. Staring up at her was a mummified person. 'That is ghastly.'

The mummy was beige in colour and its ribs were poking outwards. Its eye sockets were black and without eyes and its grotesque mouth seemed to move slightly. Its feet didn't exactly look indestructible and you could have easily scooped them up with one finger and thumb. A large blue ribbon stopped anyone from touching it.

'Apparently this mummy was a female called Catalina,' Bucky read from the grey information stand. 'Died after being sacrificed.'

'How cheery.'

'Wait,' he bent down and examined the bottom of the coffin closely. 'Look at this.'

Engraved into the stone coffin were multiple Mexican symbols according to the museum but to Bucky and Clara they didn't look earthly. They looked unearthly.

'What do you think it all means?'

'Hang on,' Clara tried to edge as close to the coffin as she could. 'I think I've seen these symbols before.'

After four minutes of scrolling through the camera roll on her phone, Clara found a picture she had taken from an adventure with the Doctor from about six months ago. The symbols were of an unknown origin and she had taken a picture of them all. Bucky was grateful. People kept walking by and staring at them, wondering why they were on the floor.

'Umma Tegubda Liches Dian Raptore.'

Just then, one of the light bulbs in the room flickered and they shot both their heads up to look at it.

'Is that what it says on the coffin?' Bucky asked her, standing up and offering out his hand to help her.

'Yep. But what does it mean? It could be a message.'

'But what kind? Good or bad?'

'Who knows?' she said.

Bucky slapped her hand as she reached for a handful of popcorn. Reeling it back in, she glowered at him and then he noticed the wooden sticks of fire on the walls.

'Adds to the Mexico feeling!'

'Yeah. Anyway, as fascinating at this exhibit is, all the dead things are starting to make me feel uncomfortable. Wanna go and have a look at the Roman pottery again?'

'Sure.'

He placed his arm around her and she grinned as they both exited the Mayan exhibit but what they didn't notice was the mummy's soulless eye sockets flashing a dazzling purple.
