'Okay, wise-guy. That worked a little, so I'll let you have that one.' Sighed Cheryl, as she pulled away. 'But don't go trying that again.'

Speed smirked. 'Glad I could help.'

Cheryl sat back down, slightly calmer and stared at the voice readings on the screen.

'What have you got?' Asked Speed, pulling up a chair next to her.

'Shouldn't you be working on that explosion?'

'We have. The explosion was because of a gas leak.'

'A gas leak? Since when would there be a gas leak in a student dorm?'

'When the student has a canister for his own personal science experiments.'

Cheryl frowned, 'so what caused the spark?'

'According to trace, xylene, or more specifically, meta-xylene.'

'Are you serious?'

'It's amazing what chemistry students can get their hands on.'

'But what causedthe xylenetospark?'

'It looks like it was left on a radiator.'

'A radiator? Which was on? In a Floridian summer?'

'Yeah, we're thinking foul play too.'

'I should think so. Not only is Xylene flammable, but what is it doing on a radiator? A chemistry student should know better.'

'We found the remains of the bottle it was kept in and managed to get a good print off it. Calleigh is running it now.' Speed pointed to the screen, 'so,' he said, 'what are you working on?'

Cheryl frowned at the screen. 'It's the voicemail of Michael Rollins. The voice isn't disguised, but that means nothing without a comparison. And I can't get anything off it, other than the stupid static in the background,' she told him, turning the volume up.

'Remove the voice, and isolate the buzzing.' Said Speed. Cheryl did as he said, and they were left with a monotonous buzzing. 'Sounds like it was recorded near an electrical generator, or something like that.'

'A generator? In Miami? That's going to be easy to find.'

'I think your sarcasm is rubbing off on Cheryl, Speed,' said Dan from the doorway. 'Although I am glad to see that you are in a slightly better mood.' He started to enter the room, and then stopped, 'what's that?' He asked, pointing at the shattered CD floor.

Cheryl flushed bright red, 'um, well.' She was feeling incredibly guilty. Not because it was a Coldplay CD, but because it was Dan's.

'Is that X&Y?' A look of alarm, followed quickly by anger flashed over Dan's face.

'I'm sorry; I'll buy you a replacement!' Cheryl grabbed her phone, and notebook from the floor, and hurried out of the lab, before Dan could pick up one of the computers and throw it at her.

'You'd better!' He yelled after her.

'I am so destructive when I'm angry,' Cheryl told Speed, who had followed her out.

'You think?' They both headed into the trace lab and pulled on some lab coats. 'So, what now?' Asked Speedle, as he watched Cheryl pull out something from her pocket.

'This is the note sent to Michael's parents. Let's see if the kidnapper left anything.'

Speed nodded, 'Okay, I'll run the glue, see if that gives us anything,' he told her, using a pair or tweezers to ease one of the letters off.

'I'll analyse the paper, then.' She told him, as he walked over to the other side of the lab and began to work. Cheryl cut out a piece of paper and placed it into a test tube, before putting the paper into a glass case to allow the cyanoacrylate fuming process to run whilst she began the paper analysis.

A few hours later, and both Cheryl and Speed were about to compare results, when Calleigh walked into the lab. 'Hey y'all,' she greeted them, 'Do y'all have anything?' She asked them, as she sat down, flicking her long blonde hair over her shoulder.

'The glue came back as your every day superglue,' said Speed, 'but it had traces of magnesium in it.'

'Magnesium? That's an interesting ingredient.'

'I'm thinking transfer,' said Speed.

'Mmmm,' agreed Cheryl.

Calleigh nodded, 'maybe not. I ran the prints. They came back to Michael's chemistry teacher. UM check all their teachers before they are hired. I sent PD around to talk, but I think I may go myself.' Ring me if you find out anything new,' she told them, and bounded out of the lab.

'What did you get?' Asked Speed.

'Strangely, there were traces of plutonium on the paper. Everything else is running through the computers.'

Speed looked at her. 'The humming makes sense, now.'

'Sorry?'

'In the background of the voicemail. It was made near the power plant.'

'So we have a location.' The computers started beeping at her. 'Seems we have something else, too.' She walked over to the first computer. 'The letters in the letter came from Helvetica Chimica Acta, which is a Chemistry publication, by the looks of things.' She pulled up the other window. 'And we have a hit on the fingerprint I found on the letter. It's,' she looked up at Speed and smiled, 'Stuart Pinkels. This is also hitting a match to the print Calleigh just ran. Do you want to ring Calleigh and let her know, whilst I run and grab a top of some description, and I'll meet you outside by my Hummer?'

She didn't give him any chance to answer, before she tore out of the lab and to the locker room.

- - - - - - - - - - -

Twenty minutes later and Cheryl was racing down the streets in her car, wearing a black sweater she had found in the bottom of her locker. Speed hung up the phone. He'd just called Horatio to update him on the situation.

'He's having a hard time trying to convince the Rollins's not to go do something stupid.'

'He's not telling us to wait for him?' Asked Cheryl, quickly switching her attention from the road to him.

'No, he thinks we can handle it. Will you watch where you are going!' He shrieked at her, clutching at the support above the door.

Cheryl rolled her eyes and turned back to the road. Before long, they were pulling into the power plant. Cheryl followed the road around to the back, sure that if the Hummer was going to be anywhere, it would be where there where very few people would be around. Sure enough, hidden behind a cooling tower, was the abandoned Hummer. She pulled up a few metres down the road, and the two CSIs got out of the car, their guns drawn.

'Miami Dade Police!' Shouted Speed.

Nothing. The two worked their way to the car slowly, their guns still out. Speed pushed forward and opened the door. The car was empty.

'I suppose that shouldn't surprise us,' said Cheryl, as the two put their guns away. Cheryl went back to her Hummer to pull out her kit, whilst Speed called in for a tow truck.

'It's a busy night,' he told her, when she returned, 'they're going to be a while.'

'It's okay, we can get going and process as much as possible.' She looked at her watch. It was coming up for nine. 'We don't have much time left.' She knelt down and opened her kit. Several of her glass collection containers had broken. 'Crap.'

'What did you do to your kit?' Speed lent over and grabbed a pair of gloves.

'Dropped it earlier. Someone must have put it in my trunk for me.'

She pulled out a pair of gloves herself and grabbed her torch. 'You take the inside, I'll do out?'

Speed nodded and jumped in the passenger side, and started by pulling a hair from the headrest and putting it into an evidence bag. Cheryl worked her way to the front passenger side, and started taking photos of the damage the Hummer had incurred when it had run Eric off the road earlier. After collecting some paint transfer, she turned her attention to the wheels. There was sand and something salt-like stuck in the tire treads. She photographed it, and took a sample. And then she moved onto the ground nearby.

On the floor, her torch picked up a ring. She walked over to it and picked it up. It was definitely a man's ring, gold, thick and set with a red stone, most likely a ruby. She slipped it into another evidence bag, before turning her attention to the tire treads left in the dirt road.

Following procedure, she lay down the measure guide and took some photos, all the while, sure that the worn treads belonged to a Volvo. An old one, judging from the worn pattern.

She headed back to her car and put the evidence in the trunk, along with her kit, before starting to return to the car to help Speed finish up. She had barely gone a few steps before Speed was running towards her, tackling her to the ground.

'What the hell-'

The hummer exploded.

Well, thank you for continuing to read this. I hope you are enjoying reading as much as I am writing!

I'm going to go write the next chapter now - i hope to have it up as soon as possible. Thank you for all the reviews!
