Tears began to spill down her cheeks. “I don’t understand.”
So I told Helen everything. I told her about the list, and how Ahmed used Viyaja to threaten everyone on the Council, including me. I told her about Jin and the messages he’d intercepted and how I believed that Ahmed was in cahoots with the pirates. And I told her about North Point and what had happened there, including the video conference where I saw Jamal.
“So now you understand, don’t you? I can’t send him up there… not without knowing what they’re up to,” I said.
I could tell she didn’t fully understand, but at least she had stopped crying. She dried her eyes with her apron and stood up straight with her chest pushed out. “Well then… you better get cracking.”
“I’ve been cracking ever since I got my hands on Jin’s data mat. I’m just not finding anything useful. He was a clever guy… too clever.”
She walked over and took my empty cup, stared me in the eyes, and said, “Poppy cock! You are just as clever as he was. I knew Jin too, you know. He used to come in here and have tea with me sometimes back when you boys were putting up that tower. Such a sweet man.”
Raising my eyebrows, I said, “Sweet? Not exactly the adjective I would use to describe him. Smart, yes. Clinical, definitely. But sweet… no.”
“Well I guess you didn’t know him as well as you thought. All the man used to talk about was his family. He went on and on about them. Used to say how the only thing important in his life was his family. They meant everything to him, you know.”
I knew that he was a family man, but he didn’t talk about them much to me. Maybe he knew the pain that it would cause. The only time I remember him mentioning something about family was when he spouted off those stupid Chinese proverbs like ‘A happy family is but an earlier heaven’ and ‘The strength of a nation derives from the integrity of the home.’ His favorite was ‘A man searches the world for what he needs and returns home to find it.’
I jumped to my feet and said, “That’s it, Helen. It has to be. You’re a genius!”
I kissed her on the cheek and ran out of the kitchen. As I ran past the tables in the dining room, I heard Helen say, “Glad to be of help.”
William was still on his bed playing video games when I returned. He gave me a quizzical look as I grabbed Jin’s data mat and sat down.
By now, I knew the folders and their contents better than the trail around this island. Every folder was meticulously labeled and all of them contained files related to the IICN or the satellite hacking project. The only exception was the one labeled ‘Family.’ It was the one I had barely examined. It only contained photos and videos of his family, some taken in China, but most on the island.
I created a new folder and then copied each picture into it. Then I searched through his apps until I found a pattern recognition tool.
It took the tool about ten minutes to analyze the first picture in the folder. After I finished running the tenth picture through the app and I received another negative match, I said, “Shit! It’s gotta be here.”
“What are you doing?” William asked.
“Huh,” I said, looking up to find William peering over my shoulder. “Oh, it’s kind of complicated.”
“I’m not stupid, you know. I wrote that video game on my own.”
“You’re right. I’m sorry.” I smiled. “It’s a tool that your dad, Jin, and I had used to analyze signal patterns over the network. It’s pretty basic, uses something called an SVN model. That stands for Support Vector Network.”
He nodded as if he understood, but I could tell from the expression on his face that I had already lost him.
“The SVN model recognizes data patterns by using a non-probabilistic binary linear classifier regression algorithm.”
“Oh.” He nodded again. “So what kind of pattern are you looking for?”
“That’s just it… I don’t know. I think Jin left me some kind of message embedded in one or more of these photos.”
His face brightened up. “I get it. It’s like those holograms. The ones you stare at and then eventually you see a hidden picture inside?”
“That’s right. But to find an embedded picture, you need to know how to look at it. It’s not as easy as you’d think.”
There was a whole academic field dedicated to it called steganography. I wasn’t an expert in the field. Hell, I barely passed the class in college.
“So if you don’t know how to look for it, how can you find it?” He said.
“I configured the app to look for any known patterns. Here, see?” I pointed to the screen. “I set the pattern probability to ninety nine percent. The tool analyzes the pixels that make up the picture.”
A window popped up on the data mat to let me know that it didn’t find any patterns. I selected the next photo in the list, a recent family shot taken in front of Jin’s hut, and I let the tool do its thing.
“Is there anything I can do to help?” William asked.
“No. It just takes time. Probably be another few hours before—”
A window popped up again, but this time it read:
POSITIVE HIT: 99.999% CERTAINTY
PATTERN FOUND: RIEMANN ZETA-FUNCTION
“Holy shit!” I said.
William leaned over and read the screen. “What’s a Riemann Zeta-Function?”
I shook my head. “I have no idea.” Math wasn’t my strong suit. “But whatever it is, it’s the key to seeing the hidden picture.”
After a few minutes of reconfiguring the tool, I had it pull out the bits that fell within the pattern and then reassemble them into a binary file. When it was done, I opened the file with a text editor.
“That sneaky son of a bitch!” Smiling, I turned and grabbed William by the shoulders. “We did it. Look, there’s the message.”
Stepping back out of my reach, he said, “You did it. I didn’t do nothing. I just asked stupid questions, that’s all.”
I stood up. “What are you talking about? I wasn’t getting anywhere until you jumped in. From now on, we’re a team. We’re going to solve this problem together. Deal?” I held out my hand.
He looked at it for a second and then shook it. “Deal.”
Chapter 13
The morning sun illuminated the room. But it wasn’t until I felt the rays pouring through the skylight that I realized it was well into the next day.
I hadn’t pulled an all-nighter like that since I was back in college. I chuckled at the thought of how many gallons of soda and how many pounds of chips I’d consumed trying to meet a homework deadline. Only this deadline was different and the realization of it drained the smile from my face.
I looked over at William. He was staring intently at his data mat. I knew that look. It was the look of a seasoned coder in the zone, oblivious to the world around him.
Last night he’d come up with an idea to bootleg CPU cycles from inactive data mats around the islands. There were probably some pissed off people wondering why their data mats ran so slow, but I didn’t care. His idea had cut the processing time from a few days to ten hours. For the first time since I had started looking through Jin’s data mat, I actually believed that we might be able to decrypt those messages before the ship arrived. Scratch that. I was positive that we’d decrypt those messages. We had to. William belonged up there. I knew that now. After seeing what he was capable of last night and knowing what he could do for the colony… hell, I’d pack him in a box of plantains if that’s what it took to get him up there.
My data mat beeped. It was another message from Shannon. I deleted it. I didn’t have time for her bullshit now.
“It’s done!” William said without looking up. “The last picture is done.”
