A/N: Thanks to Twilight Rose2 for the inspiration for this story. Since Avatar has ended, I've been having a dry spell where my Muse ditched me. But I'm back and all my stories will be updated. Woot! Anyway, if the August contest isn't over, then this is for the contest.

Rules:

This month's is something easy and fun. The gAang gets stuck in a mall for one whole night. It's your choice whether the stores are open or closed or if there's anyone else there. But there's a twist, this isn't just a simple fun overnight trip. I want mystery! Danger! Maybe even a murder? It's all up to you :D No sex scenes, oneshot or multichaptered, AU, someone must say "Okay, let's split up and search for clues", it must have mystery. MUST.

Full Summary: When the mall closes early, Sokka, Katara, Aang and Toph get stuck inside. To make matters worse, Azula, Ty Lee and Zuko are stuck with them. Azula challenges the GAang to come to a séance the three of them are holding. They want to talk to the ghost of a man who murdered a girl in the house that used to stand where the mall is now. But when the light goes out, Sokka senses something is going to go horribly wrong. And he's right. When the lights come back on, Azula is gone. Before long she is found murdered. And then another person from the séance dies. The remaining survivers know they must find out what has happened, or they may be next. And someone knows more than they are saying.

Chapter 1: Disappearance

"Can we please get out of here?" Toph whined for what seemed like the fifth time that night. She was standing outside the door to the women's dressing rooms. The mall was closing in five minutes according to the loud speaker. "The mall is closing." If it had been any other place, Toph wouldn't have given it a thought. But there was nothing less fun than watching Katara try one clothes.

"That's impossible," Katara's muffled voice said. "It's seven o'clock. The mall doesn't close until ten. It's probably just a mistake."

She emerged from the dressing rooms with her old blue t-shirt and jeans back on. Taking the dress she had been planning on buying, the two of them headed from the back of the store to the cash register in the front. There was no one there. Huh. Toph was sure she had seen someone a few minutes ago. But they could here no one in the shop. In fact, looking outside, the only people were their friends, Sokka and Aang. Leaving the dress on a rack, they headed outside.

"Where is everyone?" Katara asked Sokka.

"The mall closed a few minutes ago. We figured we'd wait and a security guard would let us out," he explained.

"But, it's too early for the mall to close."

"Everyone left, Katara. The mall is closed," Aang said, not unkindly.

"Look, who cares? Let's just go downstairs and get a guard to let us out so we can go home," Toph snapped.

"Too bad there aren't any guards down there."

The four friends whirled around. Standing behind them were Azula, Ty Lee and Zuko. Azula was glowering at them, her arms folded across her too-tight midriff shirt. Ty Lee was bouncing on the balls of her feet, grinning as usual. Zuko on the other hand, looked rather uncomfortable and out of place. Perhaps that was due to his company; he usually never hung out with his sister and her friends. Or perhaps it was because it was the mall and he hated the place almost as much as Toph did.

"How do you know?" Sokka demanded.

"Because, we're stuck here too," an irate Zuko barked.

It was then that Katara noticed that they weren't empty handed. Azula had a handful of candles and Ty Lee had wrapped herself in some kind of odd-looking dress. It was brown with crosses and weird patterns. She also had her head covered. All together, she looked ridiculous. All of this escaped Katara's mind. They were stealing!

"You can't just take that stuff!"

"Sure we can," was Azula's cool reply. "Our father owns this mall."

"What are you doing with those things anyway?" Toph asked, her curiosity getting the better of her.

"Oh, we're holding a séance!" Ty Lee chirped.

Both Zuko and Azula shot her dirty looks. But then, slowly, Azula turned to them.

"Would you like to join us?"

"Why on Earth would you hold a séance in a mall?" Toph snorted.

"You don't know?" Ty Lee leaned forward as if she was telling a great secret. "The mall is haunted. It was built on the ruins of an old house where a man named Benjamin killed a girl named Serenity. Both their ghosts haunt the hallways of the mall since their home was destroyed. Azula wanted to see if we could talk to them."

"Ghosts?" Toph cackled. "You believe in ghosts?"

"Ty Lee says she can contact the dead," Azula informed them, ignoring Toph. "You want to come?"

"No way!" Aang protested immediately. "You'll probably tell them we stole the stuff."

"Scared?"

Zuko shifted on his feet, obviously impatient.

"No we are not!" Sokka yelled.

"Prove it. Come to the séance."

"Fine! We will!"

Azula smirked as if she had won the lottery. "This way," she told them.

They would be holding the séance at the Hot Topic in the corner of the mall by the stairs. There were black curtains drawn across the window and the black "closed" sign took up the entire window on the door. Ty Lee immediately told them to sit in a circle. She locked the front exit to the store. Azula sat to her right with Zuko next to her. Sokka sat next to him. Then came Toph, Katara and Aang directly to Ty Lee's left. She placed the candle in the middle of the floor and then lit it with Zuko's lighter. No one ever knew why Zuko carried it around. He didn't smoke or anything. Ty Lee got up and switched off the light before coming back to sit in her spot. The candle light was meager and showed everyone's faces only slightly.

"Everyone needs to hold hands," Ty Lee said quietly. They all did. "Spirits! I call upon the spirit of Benjamin! Are you here Benjamin?"

There was electricity in the air. Sokka did not know if this was just his own fear or an actual spirit. He was shaking. The candle light started flickering. He could hear fast breathing from his left. It wasn't Zuko though. It was Azula. And she was scared.

"Can you hear me, Benjamin?"

Suddenly there was an ear-piercing shriek from Azula. Zuko's hand yanked out of his.

"Azula!" he heard him call.

Azula went right on shrieking and then something knocked over the candle. All of them reached in, patting out the fire before it could spread. The shrieking stopped and someone could be heard running for the lights. The flicked back on. Azula was gone.
