I pulled my cell and called Bug and told him to hack the Vatican or whoever certifies priests. “If these Nicodemus guys are legitimate clerics,” I told him, “then there should be records in the registry of holy orders. Find out.”

I slipped the cell back into my pocket.

“Nicodemus is a strange man,” said Violin. “I saw him a few times when I was a little girl down in the Shadow Kingdom.” She cut me a look. “That’s what they call it.”

“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.
