Chapter 1

Catherine Willows pulled in at the side of the road and stepped out of the large black car. The air was warm and heavy, and dark clouds were brewing above her. She knew she had to clear the scene before the rain washed away any potential evidence. Picking up her case, she walked over to Nick and Warrick.

All Catherine knew was that the murder had taken place at a high school on prom night. Grissom had phoned her on her night off, so naturally, she wasn't happy to be here. She fought off a yawn and continued walking.

Looking around, she saw that all the students were being held in the dance hall for questioning. Once she reached Nick and Warrick, she knelt down on the road and put some rubber gloves on.

"Hi, sorry I'm late." She whispered, looking down at the girl.

"No problem Cath," Warrick replied, "you haven't missed much."

"Is the coroner here?"

"Yes, I'm here!" Catherine looked over her shoulder to see David waving at her. She smiled- you could always rely on David to lighten the mood. He walked over and stood next to Nick.

"COD?"

"Asphyxiation due to strangling. We'll find out more after the autopsy."

"Thanks David."

"Anytime." David slowly turned and walked over to the van to collect a body bag.

"Does she have any ID on her?"

"No, but some of the students identified her as Nicole Jones." Nick said.

"Nicole Jones?"

"Yes, why?"

Catherine looked down at the girl again. This time she recognised the curly auburn hair and glowing green eyes. Her pretty blue prom dress was torn at the bottom and the neckline was stained with blood.

"I know her- she's one of Lindsay's friends." Catherine suddenly remembered. She had met Nicole at one of Lindsay's birthday parties. Lindsay was here too, it was their school's prom.

Cool droplets of rain began to fall, bouncing off the tarmac. A loud crack of thunder echoed around the car park. "We need to get out of here!" Nick shouted. "Take as many photos as you can before the rain destroys the evidence!" Everyone else suddenly started rushing around in the rain, but Catherine didn't move. She just stared into the girl's lifeless eyes.
