Cheryl was lying on her back, staring up at the underneath of the car, when three sets of feet appeared next to the car.

'You know, I checked that car for evidence already. There is nothing there.' Came Eric's voice.

'I'm not looking for evidence. I'm looking for a number.'

"I'm not sure under a car is where you're going to find the number of your next boyfriend.'

Cheryl shot out of the car and looked up, 'ha ha, Speed. Very funny. Actually, I was looking for this.' She got to her feet and wafted a piece of paper around. On it was a very long number.

'What's that?' Asked Calleigh.

'Mazda decided to try a prototype GPS system on their Miata's. Basically, if the car was stolen, you'd call up with the registration as per normal, but, if you wanted to know where exactly the car had been, you'd check the little black box, metaphorically speaking.'

'And what's the little black box?' Asked Eric.

'A twenty-seven digit code, that's found on the box, under the car. It sends a message via satellite to a computer, where it's stored for three weeks, before it's over written.'

'And how do you know about this?'

'Well, much as I'd love to say I created it, I'd be lying, as my speciality is engines, not electronics. However, after tweaking my Hummer, and all the moderations to my other cars, I placed the same GPS system on my cars, so I know how it works.'

'So, let's run it through the computer.'

'Ah, that's where the problem lies.'

'And what's the problem?' Asked Calleigh.

Well, technically speaking, you need to get it through Mazda, but I've already spoken to my friend there, and their computers are on the blink.'

'And what use is that to us?'

'If you look at it that way, it's bad, but I happen to have a copy of the programme myself. So, wait a minute and I'll get my Hummer in.' And with that, she hurried out of the garage before the others could say anything. They were still standing there when she drove the car in minutes later.

She hopped out of the car and headed to the back door, before opening it for the others to see.

'Whoa,' exclaimed Speed, who hadn't seen all the extra items of kit earlier, 'I know where I'm going when I get short.' But the back of the car was also impressing Calleigh and Eric who had only seen it in the dark, and briefly.

'Oh my lord,' said Calleigh. The back of the car was impressive. Inside was the most enormous sub and two speakers. But in the centre, in the back of the rear seats, was a black panel, matching the leather interior.

'How much does the NYPD pay these days?' Asked Speed.

Cheryl ignored him, and pressed a button on the car keys. It flicked down the panel to reveal a built in computer. 'This computer contains all my music, but it also contains one of the copies of the GPS software. The other copy is on my home computer, just in case this gets stolen… although good luck to them,' she half explained, as she began hitting keys on the keyboard.

'Okay, hang on a minute. I'm serious here, how on earth have you managed to get a car like this?' Asked Speed.

Cheryl stopped what she was doing and turned to face the others. They were all looking very curious. She took a deep breathe. 'I love cars. I love the freedom of driving. I love the sound of the engine. I just love cars. I did my engineering degree and developed my own kind of engine. It's similar to the engine in this one, although a lot less sophisticated version, actually. And I've sold the design, and now, well, lets just say, it pays for the cars.'

'Are you serious?'

'Yeah.'

'So what's so good about your engine?' Asked Eric.

'Well, I can over 800 miles out of a tank of gas, on this thing… and the tank is only 10 gallons.' The others let out various cries of surprise. 'Look,' she said, as she began typing in the code, 'we can discuss this after we've tracked this car.'

'And why are we tracking this car?' Asked Speed.

Did you find anything at Carla's house?'

'We found the gun. We found several, actually, but none of them was the one that was fired in the club.' Explained Calleigh.

'Did you guys find anything at the club?' Cheryl asked as she waited for the information to be sent to her.

'Yeah, an ID.'

'Who's?'

'Well, here's the thing. We found this ID, the prints match the one's off your glass, Mark's.' Said Calleigh.

'But Mark isn't his name,' said Speed, 'the ID was "Mark Wahlberg".'

'There's nothing more to go on with that case.' Said Calleigh.

'And what about the shooter?'

'Nothing.'

'And that's why I'm at my computer. Basically, we know she was shooting. But she went to the range to cover the GSR trace she knew we might find on her. So if she didn't dump the gun at the club, then she dumped it between the club, and the range.'

'How do you know she didn't dump it after going to the range?' Eric asked her.

'Because, she's clever. She knew the car might get traced before the left the range, so she wasn't going to risk the gun being found in it. And this,' she said, pointing to the screen, 'shows exactly where she stopped, en route to the range, for exactly six minutes. Long enough to dump the gun.'

'I'll come with you,' said Speed.

Cheryl shut the door, and made to move around to the driver's seat, when she stopped. She turned around to face Calleigh and Eric. 'I'm such an idiot,' she exclaimed. She unbuttoned the top of her overalls to reveal her dress.

'Now's not the time for dancing, Cheryl,' said Speed, staring at her.

Cheryl just glared at him. 'I'm wearing part of the crime scene,' she said to Calleigh and Eric. 'There may be traces of him, on me.' She ran back round to the trunk and pulled it open. Next to one of the speakers, hidden in the side of the wall, was a little compartment. In it was a spare set of trainers, a pair of shorts, and a little, white vest-top. 'Oh, give me a break,' muttered Cheryl, as she pulled the clothes out.

She looked at Eric and Speed, 'look, I'm about to take the evidence off and get changed. I have no intention of trying to find my way back to the locker room either,' she told them, as she began pulling the overalls down to her feet, leaving her back in her heels and dress. She bent over, picked them up, and dumped them in a brown bag which she handed over to Calleigh, 'sorry, but I don't know if anything transferred onto the inside of the overalls.'

Seeing that the men had turned around, she quickly pulled off the shoes and dress, and dropped them in a separate bag, before pulling on her other clothes. Once changed, she hurried round to the driver's seat and jumped in. 'Come on, Speed, if you're coming. We're going.'

Speed raised an eyebrow at Eric, who was pulling a face at him, before joining Cheryl up front in the Hummer. 'Were you serious about the engine?' He asked her, as they pulled out of the crime lab garage.

'Yes.'

'But, you're a girl. What do you know about engines?'

Cheryl leaned over and punched him as hard as she could on the arm.

'Hey!' He objected, rubbing his arm.

'Timothy! What is the deal with girls and cars? You don't have a problem with Calleigh and guns!'

'I'm sorry, but you constantly surprise me.'

'You should stop spending so much time with Delko. He said the same thing earlier.'

'You are going to have to explain a few things about yourself, you know.'

Cheryl glanced over at him. 'Whatever,' she said, pressing a few buttons on the touchscreen on the dashboard. Within seconds, loud rock music was blaring out of the speakers in the back. She turned the music down slightly.

'The Who?' Asked Speed

'One of the greatest bands in history.' Said Cheryl, nodding her head.

'Which song is it?'

'Wont get fooled again.'

Speed looked out of the window, 'Cheryl,' he said, eventually, 'I'm sorry if I upset you.'

Cheryl pulled over, having finally reached their destination. 'I'm sorry if I hurt you.'

Speed laughed, 'you pack a punch there. Where did you learn to hit like that?'

Cheryl looked over at him, an expression in her eyes which he couldn't quite read, before turning of the engine and jumping out.

In front of them was a drainage ditch containing water about half a foot deep. The sun was slowly beginning to rise over the horizon. Cheryl stood staring at it, as Speed walked over to her, joining her on the embankment of the ditch. 'I didn't realise how late it was getting.' She said, mainly to herself, 'pretty, isn't it?'

'Yeah.'

Cheryl turned to grab her kit and noticed Speed staring at her. 'What?'

'Nothing,' he told her, before reaching down and grabbing his torch from his kit. Cheryl grabbed hers and the two began shining their lights across the murky water.

'I think we're going to have to go in.' Said Cheryl. She leant over and slipped her trainers off, before lowering herself in the water. 'Man, this is cold!'

'You should have shoes on,' Speed told her, as he rolled his trousers off. 'You have no idea what's in there.'

'I was hoping for a gun.'

'That's not what I meant, and you know it.'

'I know, but I have no other shoes with me, and I don't want to drive back bare foot. I'll be fine. I'm more worried about alligators.'

'Gators in the sewers are a myth.'

'Firstly, Speed, this is a drain, not a sewer, secondly, you come from New York, not Miami, and thirdly, there was a case in New York not so long ago where a sewer worker was killed by an alligator.'

'I have lived here for a while, Cheryl. Besides, I listen to what Delko tells me.'

'Yeah, you proved that earlier,' said Cheryl, pointing the flashlight at him. 'Why is the water so deep?' She asked, before he could apologise again, 'it hasn't rained for ages.

'It's the water that's come down from further upstate.' The two of them continued to wade through the water, until Speed's light picked something up. 'I think I've got something.'

Cheryl hurried over, carefully placing her feet. She shone her light over Speed's, seeing the gun instantly. She pulled a glove out of her pocket and put it on, before leaning down, and sticking her hand in the water to pick up the gun. 'This had better match the bu-' She stopped and looked at Speed, 'what is that rumbling?'

They both turned around. Not too far off, a wall of water was heading towards them, along the drain. 'Speed, move!'

They ran towards the sides, the water heading towards them. Cheryl flung the gun towards the car, not hearing it land on the gravel over the roar of the water. She leapt up at the banking and heaved herself up, ignoring the immense pain she was feeling in her feet, before turning to see what Speed was doing.

At some point, he had tripped and was just reaching the bank. Cheryl reached out and grabbed his hand, as the wall of water came crashing down over him. He pulled with such a jolt, it felt like her arm was being yanked out of its socket. And then she felt his fingers begin to slip from hers.

She flung her other arm into the water, and over his wrist, before pulling with all her might. She wasn't quite strong enough to pull him out, but she was strong enough to hang on to him.

Finally, just when she felt she couldn't hold on any more, the water began to subside, and she was able to pull him out, and drag him onto the grassy bank. She turned him over. He wasn't breathing.

Without wasting another second, she began the CPR she had been taught, but had only ever had to use once. She didn't know how long she had been pumping his chest, nor how long she had been breathing into him, but finally, after a breath, as she pulled away, he took a deep breath and began choking, coughing up the water.

Cheryl sat back and took a deep breath, suddenly aware that the only time she had been breathing, was when she had been breathing for him.

Slowly, Speed sat up and looked over at her. She was shaking uncontrollably and there were tears streaking down her face. He scuffled over before wrapping his arms around her. She looked up at him, watching the water drip from his hair down his face. 'That's the second time I've saved your life, and that's the same number of days that we've worked together.' She told him, her words almost tumbling over each other.'How on earth have you managed to stay alive all this time?'

Speed said nothing, instead leaning over and kissing her.

Thanks for reading. I hope you are enjoying it. Hmmm, you know, although I said I wasn't bothered about reviews, it would be nice to know people are reading, even though I'd continue to write anyway, so if you fancy making my day, just leave me a little message saying you've read it. It only takes a minute, and you dont have to say whether you liked it or not, or what worked and what didn't...
