Jonathan Maberry - Assassin's code

“Yes, very dramatic,” I said sourly. “Can you give me a physical description of Nicodemus?” She did, and I felt my skin crawl. “Okay, that’s a step over the line into weirdsville. That description exactly matches the inmate.”

“What happened to him?” asked Violin.

“He disappeared.”

“How did he escape?”

“I didn’t say he escaped,” I said. “He vanished from his cell. No evidence at all of a jailbreak. Security cameras went haywire, guards saw nothing, and then he dropped completely off the radar. I was there when it happened. Thoroughly creepy and borderline impossible the way it happened. But even so, it couldn’t be the same man. Could it?”

Before she could reply Church appeared in the doorway and snapped his fingers for us, and we hurried over. Lilith was with him. “Circe,” he said into the phone, “you’re on speaker. Repeat what you just told me.”

“When Rasouli gave the flash drive to Joe, he mentioned the Book of Shadows. When Lilith sent us her scan she included a note saying that Arklight believes that the Book is the secret history of the Red Order and the Holy Agreement. It’s in ciphertext, however, and it’s unreadable. Arklight had it for years and couldn’t crack it. The same ciphertext is used in a book called the Voynich manuscript, which is in a library at Yale. We now have both complete texts, and the language is the same. With me so far?”

She didn’t wait for an answer and instead plunged ahead.

“Rasouli also mentioned the Saladin Codex, which is a text on mathematics. MindReader pulled multiple translations of it and just finished a comparative analysis. The Codex is a work of minor importance and one with a number of flaws. Now, from a distance, we have two unreadable books and one that is readable but seems to be entirely unrelated to this matter.”

“That’s from a distance,” I said. “How about close up?”

“Well… Rudy and I may have made a little progress,” continued Circe. “First, you have to understand that ciphertext isn’t a code. It’s mathematical. However, even when using MindReader to analyze the Codex for a key to the cipher we came up dry. But here’s the thing, and this changes everything… this is where the Voynich manuscript comes in.”

I looked at Church and saw him stiffen. Lilith, too. You could feel the tension crackling all around us.

“We think the Voynich manuscript was allowed to be found by the Order. It puts it out there so that anyone can find it and read it. Every page is on the Net. They don’t care if the average person finds it-it’s gibberish to them. However, if you have that as a reference, and you have access to the other two books, then you can read them all.”

“How do you know?” I asked.

“Because,” said Circe, “we found the key to the cipher.”

“ What? ” demanded Lilith, almost in a shriek.

“At least we think we’ve found it. Bug is programming it into MindReader right now. He says that we should have a full translation within hours.”

Lilith shook her head. “We’ve spent years trying to make sense of it, and we have looked at the Codex as well. There is no key to the ciphertext.”

“There is,” insisted Circe, “and it’s in the Voynich manuscript. Rudy figured it out. Or, he kicked off the line of thinking that’s brought us to this point. He said that we’re overthinking this. You see, if the Book is the history of the Agreement, then the Red Order and the Tariqa want their members to be able to read it. Otherwise… why write it down?”

“Makes sense,” I said. “How does it help us, though?”

“Well, we backed up and looked at the issues of translation from the perspective of two ideologies, two cultures who are effectively at war on a permanent basis. They have different customs, different languages, different points of reference on virtually everything… except one. There is one area in which all advanced cultures can agree, language differences aside.”

I had no idea where she was going with this, but Church and Lilith said it at the same time.

“Math.”

“Math,” agreed Circe. “The Voynich manuscript and the Book of Shadows are written in an invented language that has order and structure to it. Therefore it has mathematical predictability as long as anyone who tries to read it has a set of precise, immutable guidelines.”

“Such as a ciphertext,” I said.

“Yes. And the third book in our mix, the Saladin Codex is a book on understanding the science and functions of math.”

Circe was so excited that her voice bubbled out of the phone. “One of the reasons historians never paid much attention to the Saladin Codex is it was widely regarded as a well-intentioned and fundamentally flawed set of theories about math. The author was so well-respected that the book was given a place of honor in a museum, but it was an open secret that al-Asiri was no true mathematician. Certainly not by the exacting standards of the Muslim world, and let’s remember that they invented algebra.”

“Is the math in the Codex actually flawed?” I asked.

“Yes, but now we no longer think that al-Asiri made a mistake. We think that he made a very precise set of deliberately flawed computations. Thousands of them. And somewhere in those flawed numbers is the key to the ciphertext.”

“How’s the Voynich book play into it?” asked Church.

“There are celestial charts and drawings all through that book. We know that algebra and trigonometry are used in celestial charting and navigation. The connection seemed obvious, or so I thought. Anyway, I had Bug use MindReader to plot the positions of the celestial charts in the Voynich manuscript, but we got error after error because the diagrams are wrong. The astrological star patterns in the Voynich book aren’t exactly in the right place. Scholars had dismissed this as the errors often found in old sky maps made before the invention of ultraprecise telescopes.

“Then Bug had the idea of trying those same calculations based on algebra and trigonometry as it appears in the Codex. Al-Asiri’s calculations have long been decried as bad math. They aren’t. They’re brilliant math, but they’re deliberately flawed math. When we charted the same astrological star patterns using al-Asiri’s skewed mathematics, they matched exactly with the star patterns in the Voynich manuscript.”

Church and Lilith looked stunned. So did many of the Mothers.

“Um,” I said, “speaking on behalf of C students in math everywhere, what the hell are you talking about?”

“Joe,” said Circe, “math is an exact science. However if you build a flaw into it, then the flaw becomes an exact flaw and every computation is exactly wrong in the same way.”

“So what? How does that help us?”

“If you look at the errors, you have a key to understanding math from a certain perspective. You can actually use al-Asiri’s errors to do proper calculations. That predictability and regularity is a cipher. It’s a key to understanding anything else that is based on the same code. We began applying it to other drawings in the Voynich manuscript. A predictable mathematical sequence is one of the most common replacement ciphers. We applied it to English and got nowhere. We tried French as it was spoken in the twelfth century, and nothing. The same thing with Arabic and Persian. Nothing. Then we thought about commonalities. Charles LaRoque and Ibrahim al-Asiri were diplomats as well as deeply religious men. They were creating an agreement designed to preserve their churches, correct? So, in what language would these men write that agreement? We thought they might have written it in Hebrew, the original language of the Old Testament, but LaRoque was a Christian and al-Asiri was a Muslim, and Hebrew was the language of the Jews. Both men would probably have had some anti-Jewish sentiments. The Bible was often translated into Greek and Aramaic. And Aramaic was the language of diplomacy throughout the Middle East for a thousand years, and virtually all Middle Eastern languages can be traced back to it; and the Aramaic alphabet was eventually adopted for writing the Hebrew language. Formerly, Hebrew had been written using an alphabet closer in form to that of Phoenician. Everything fit. We now know that Aramaic is the language used to write the Holy Agreement.”
