Will's mum Polly had travelled to the caravan park with Simon's parents, and she and Will were going to be sharing a caravan. Simon's parents would be sharing another caravan, next door to the D'Amato family. Simon and Neil would be sleeping in a tent, and Neil had brought along two thick sleeping bags because, as he told the others, "I can have one bag inside the other if it gets too cold", although as they were identical and the zips were stuck on both, Will suspected he might have a bit of a problem . Jay would be staying with his parents, in the family's own caravan.

It was evening now, and Neil was being particularly cheery, helping all the parents to unpack their things and whistling as he did so. "You seem quite happy", commented Will. "I've got a really good feeling about this weekend", Neil replied. "I think it's gonna be exciting." Exciting wasn't quite the word Will would have used to describe the next couple of days. Part mundane, part embarrassing would probably have been more accurate, what with having to dance with his mum – although he did think the spit-roasted pig at the barbecue might be nice. Just then, Polly called to him from their caravan.

"Will, I've brought along your favourite kebabs for the buffet this evening", she told him. "You mean those marinaded ones?" he asked her. "That'll be lovely, thanks Mum!" The thought of kebabs put him in a much better mood. Maybe even dancing the waltz wouldn't be too bad. And there was a glorious sunset over the caravan park. Jay and Simon were just returning from the shower block. They were carrying towels and looking a lot fresher than they had done in the car. "The showers aren't too bad, you know", Simon said to Will and Neil. "Except for one thing."

"What's that?" Neil asked.

"The shower I was in stopped working when I was halfway through. So if you two still want showers, you'll have to take it in turns."

"Shit!" said Will. "I'll let you have first go if you want", offered Neil. "Oh, thanks", Will replied, brightening up. Neil and Will fetched their towels and soap, and set off in the direction of the shower block. "Have you always known how to do that Strictly dancing?" Neil asked Will as they walked along the concrete path. "You mean ballroom dancing", Will laughed. "No, I don't do ballroom dancing, my mum taught me how to dance the waltz when I was a little boy – just as a party piece for us to do in front of relatives."

"Oh, I see", Neil said. "Do you like your caravan?"

"It's actually quite nice – for a caravan", Will replied. "My mum likes the veranda."

Neil looked confused. "Isn't that the big lady on the telly?"

"No, that's Miranda", explained Will. "The veranda's the kind of platform thing at the front of the caravan. It's just a shame the local chavs knocked down all the railings."

Dusk had fallen by the time they got to the showers, which were on the edge of the caravan park, next to a forest. "Are you sure you don't mind me going first?" Will said to Neil. "Nah, mate", came the reply. "You go ahead." Will stepped under the shower and undressed, hanging his clothes on the wooden cubicle door. Just as he had taken off his underpants, he heard Neil's voice. "Here, Will", he asked. "You don't know if there's a McDonald's round here, do you?"

"I shouldn't think so", Will replied. "It's a caravan park, so people tend to bring their own food."

"I wish I'd known", said Neil disappointedly. "I didn't bring any food except the Doritos and I've not ate nothing since lunch, and now I'm really hungry." Will smiled to himself. "Neil", he said to his friend. "Don't forget there's the buffet at the dance tonight, and my mum's made some beef kebabs."

"Oh, that sounds good", said Neil. Will turned on the shower and started scrubbing himself. Once he had finished his shower, he stood on tiptoe and opened the sliding window at the back of the cubicle to let the steam out - then he dried and put his clothes back on. Neil was absorbed in playing with his phone when Will emerged fully dressed from the cubicle but something caught his eye straight away. "Look at the moon!" he yelled. The cubicle window which Will had slid open was about a foot and a half square, and it showed an enormous full moon with a few small grey clouds scudding across. "See how big it is!" Neil exclaimed. "That's the supermoon", Will told his friend. "It's what you get when the moon is closest to the earth. If I remember rightly, they only happen every 14 to 15 months."

"It looks really lovely", said Neil, drifting towards it as if entranced. Will went outside again to get a better view of the moon. It was darker now, and the last few colours of the sunset were visible over the park. Coming around to the side of the block with the open window, he could hear Neil singing as he took off his clothes. Cow parsley was nodding in the twilight, and the cool evening air was bringing out some kind of fragrance.

The little clouds were moving away from the supermoon now, and it seemed to be shining a lot brighter. Will could hear a small dog yapping at the moon, and then an even bigger dog barking at it. Just a minute. The sound of the bigger dog seemed to be coming from inside the shower block. Was Neil okay in there? "Neil", Will shouted outside the open window, and then a huge furry creature burst through it, slightly wet from the shower. Will froze as the creature's damp fur momentarily brushed against his face, before it landed on all fours and ran away into the forest. Without meaning to, he licked his upper lip to discover some hairs left by the creature. Now springing into action, Will ran into the shower block. "Neil", he shouted. "Neil, where are you?"
