It seemed Greg was leaving a trail for them. A deep purple pickup had been recorded following Greg's car for miles, until it emerged from a country lane connecting to where his abandoned car had been found. The car had been tracked across the city, appearing to stop regularly, just off camera. Every stop became a crime scene, with blood evidence that came back to Greg every time. They followed the trail for days until they hit a dead end. The car that they had been tracking was found, abandoned in a deserted farm yard. It too became a crime scene. Nick sprayed luminol over the back seats of the car. Three distinct letters glowed back at him. Run.

Seconds after they had cleared away from the vehicle it burst into a hot fireball. Without the warning they would have been killed within seconds. Michelle had been to every crime scene, hopeful that she would be the first kind face that Greg saw when he was found. She slowly walked backwards away from the burning car and towards Nick's, desperate for the privacy it could provide. Her foot kicked something and it rattled across the road. Looking down she saw what had made the noise- a shiny disk in a battered plastic case.

'Nick?' She called out, not daring to take her eyes off the disk. The older CSI jogged over to where she stood, following her gaze to the floor. He knelt down and picked up the disk in his gloved hands.

'It's warm. Maybe it was near the car when it exploded.'

'What is it?'

'Come back to the lab and we'll find out.'

'Don't you need to finish processing the scene?'

'Nah- Finn, Sara and Morgan can handle it. Come on.'

The disk, though battered, still worked. Archie played it through the large computer screen so that Nick and Michelle could watch.

A figure sat in the middle of an empty room, tied to a chair with a sack covering his head. A long stick crept into shot and removed the sack. The figure looked like Greg but was thinner, dishevelled and clearly exhausted. Michelle let out a gasp. She hasn't seen Greg this way before and it was horrible.

'Collect me at 079 231. Bring the girl.'

The video cut off.

'They've been monitoring us. They couldn't have known about you any other way.'

'I'm going.'

'No- Michelle it's far too dangerous.'

'I don't care. I can look after myself. And, clearly, there is no other way to get him back. Put a wire on me. Give me a gun. Whatever you want to do to cover your back if this goes south. I'm going.' She stormed out of the AV lab and into the corridor. She ran through tears until she found herself on a bench outside the crime lab. Time was passing, she knew it was, but she didn't care.

Morgan's hand on her back made her jump.

'Sorry. I didn't mean to scare you. I just wanted to let you know that your equipment is all set up inside.'

'Equipment?' She sniffed

'Yeah. Nick sorted it all. Now go get our Greg back.'

Michelle smiled. Greg was coming home.
