Maddie kept her head down, working with Becky and Douglas on going back over everything.

They remapped the cave photo and pinned it with the others but just as before it gave them nothing new, no new leads. Maddie sat there staring at it for a while, seeing herself, seeing her lying there and feeling like someone or something was screaming in her head. Suddenly she got up, walked over to the board and flipped it so that there was only the white back and re-pinned it back with all the notes. Neither Douglas nor Becky said anything, if anything they acted like it had always been like that, always hidden and she was grateful that they weren’t probing, weren’t asking her what the significance was.

“There’s got to be something.” Becky muttered after hours of flitting through her notes.

Maddie sighed. It was infuriating, to think they’d got so much intel, so much data but it all led to nothing. She sat back in her chair screwing her face up.

“I’m getting a coffee.” Maddie muttered getting up and heading to the kitchen before coming back with an extra strong cup for all three of them.

“Thanks.” Becky said taking hers.

“Here’s a question, who cracked my code?” Maddie asked after taking a long sip of coffee and burning the roof of her mouth.

“On the video?” Becky said looking up.

“Yeah.” Maddie replied.

“Me. I remembered the weird hand thing you did so we figured the number bit out relatively quickly but then it took us a while to work out what it all actually meant.” Becky said.

“How’d you figure it?”

Becky shrugged. “I’m not sure exactly. It started with just number association. We thought it might be a bank account number but that made no sense. Then I just got thinking about serial numbers, and something made me check the referencing system that Homewell used for their cases and then it all came together.”

“I would have made the clue easier but I had to think on my feet. I only saw a partial name of the train station. The ‘Mark’ bit was all I saw and then the sign itself, the paintwork that told me it was a train station.” Maddie explained.

“It was pretty cool as a puzzle to be honest. Just had to really scratch my head to solve it.” Becky said.

“Sorry.”

“Don’t be. I’m just pleased we figured it out in time. We’d have never have guessed that’s where they were keeping you. It’s pretty ingenious really, because who would think to look at a disused station?”

Maddie gave her a wry smile. “I worked that case right when I started at Homewell. I was the most junior agent on it. It was a horrible one but it taught me a lot.”

“Did the guy really keep her in that tunnel?”

“Yeah. Our team found the remains. We were doing a search of the area around it and someone pulled an old map which showed where the train line used to be. Her parents were heartbroken but at least they got her back, she’d been missing for almost five years by the time we found her.”

“That’s awful.”

“Yeah but we got enough evidence to prove Harkings did it. The Police took over and he’s rotting away now which is at least something.”

“Justice done then huh?” Becky muttered.

“Something like that.” Maddie replied taking another sip of her coffee.
