Read Chapter 26: The Letter to the Queen

The candle had burned down to a stub by the time Thomas noticed the pattern. Or rather, the *mis*pattern—a single point where the ciphertext deviated from the rhythm it should have followed. His father had taught him that flaw, one summer afternoon when Thomas was twelve, showing him how a tired man’s hand will slip on the fourth character of every seventh word, as if some muscle memory overrides the mind.

The letter lay across Cecil’s desk in the safe house off Cheapside, a sheet of fine vellum covered in a script Thomas recognized with a cold prickle at the base of his skull. *His own hand.* Not literally—the ink strokes were not his—but the system was. A bilateral substitution cipher, the sort his father had devised for merchant ledgers, with a twist: digraphs were broken across word boundaries. Thomas had taught it to his father when he was fifteen, proud of his invention. He had never seen it used by anyone else.

“You’ve gone pale,” Cecil said from the window. He stood with his back to the room, watching the street below. “Is it the cipher, or the contents?”

Thomas did not answer. He read the plaintext again, his finger tracing beneath the lines he had decrypted in his own careful scratch on a separate sheet.

*My lord, the fleet is ready. The Queen’s guard has been reduced to forty men on Sundays, when she attends chapel at the private gallery. Lady Jane will be crowned at the Tower by the eighth. The French ambassador waits only on your word, and the gold has been delivered to Calais in three separate shipments, as you instructed. The printer’s boy will not trouble us long.*

That last line. Thomas read it again. *The printer’s boy will not trouble us long.*

“It names no one,” Cecil said, turning from the window at last. His face was unreadable in the dim light. “Unsigned. We cannot bring this before the council.”

“It doesn’t need a signature,” Thomas said. His voice sounded strange to his own ears. Flat. Hollow. “The cipher itself is the signature.”

Cecil raised an eyebrow. He moved to the desk and stood over Thomas’s shoulder, looking at the decrypted text. “Explain.”

“This cipher is mine. I invented it. I taught it to my father three years ago, in the shop on Fleet Street, when we were supposed to be oiling the press but instead spent the afternoon with quill and parchment. He was the only one I ever showed it to. Not even—not even Roan knew of it. I was proud of it. I thought it made me clever.”

Cecil said nothing. He had the patience of a man who had spent his life waiting for others to reveal themselves.

“My father taught someone,” Thomas said, staring at the vellum. “Someone close enough to him to learn his deepest secrets. And whoever that is used my cipher to write this letter. It took me an hour to break because I kept assuming the keyword was something my father would choose. A print shop term. A line of scripture. A ship’s name.” He swallowed. “The keyword was *Eleanor*.”

“Your mother’s name.”

“She died when I was nine. My father never spoke of her openly, but he kept her portrait in a locked drawer. I found it once, after he vanished. He had written my name and hers on the back, with a date. I never told anyone that.”

Thomas turned the vellum over, as if the reverse might hold another secret. It did not. The letter was clean, carefully written, the kind of deliberate script a man uses when he knows the document may be examined. The lack of a signature was not an accident. It was protection.

“So the author knew your father well,” Cecil said slowly. “And you believe that person is Howard.”

“That’s the difficulty.” Thomas set the vellum down and massaged his temples. “My father was poisoned by Howard. John Finch didn’t survive long enough to name his killer’s accomplices, but he was certain Howard was the Cipher. But this letter—this cipher—it’s from someone *inside* my father’s confidence. Howard and my father were enemies. They never met as friends. So either Howard somehow stole my father’s private invention, or…” He trailed off.

“Or someone trained by your father is writing letters on Howard’s behalf,” Cecil finished. “Someone who knows the cipher, knows your mother’s name, and knows about you.”

The room was very quiet. The sounds of Cheapside filtered through the shutters—a cart rumbling past, a hawker crying fish—but they seemed to come from a great distance.

“Read the letter’s date,” Cecil said.

Thomas looked. “Three weeks ago. Postmarked from a village outside Dover, based on the seal’s wax. Common grey, the sort a minor household uses. Nothing traceable.”

“And the hand?”

“I was a printer’s apprentice. I read hands the way other boys read weather. This one is educated but forced, as if the writer is copying his own hand carefully. He’s hiding his natural strokes. But there’s a habit he can’t hide—the way he dots his *i* slightly left of the stem. My father did that. He said it was because his hand cramped from press work.” Thomas’s throat tightened. “I taught him to break that habit. He never could.”

“So this is his student.”

“Or his kin.”

Cecil went very still. He had the stillness of a hawk sighting prey. “Explain.”

“My father was in Howard’s circle long before anyone knew Howard was the Cipher. He staged his own death to hunt him from within. He said he got close enough to be poisoned. But in that time—if Howard learned of my father’s methods, if someone in Howard’s household was close to my father, befriended him, learned his ciphers—” Thomas shook his head. “I don’t know. It’s speculation. But someone who knows my mother’s name, who writes in my cipher, who signs nothing, and who speaks of me in the past tense as a problem to be solved—that is not a stranger.”

“Your father had no other family.”

“He had none that I knew of.” Thomas paused. “But he kept secrets even from me. He told me I was an apprentice, not a son, because he feared for my safety. He may have kept others safe the same way.”

Cecil studied him for a long moment. Then he crossed to a small coffer in the corner of the room, unlocked it with a key from his purse, and withdrew a single sheet of paper. He held it out to Thomas.

“I had this from my own source three days ago,” Cecil said. “I have not been able to break its cipher. It may be unrelated. It may not be. But its source is the French ambassador’s household.”

Thomas took the paper. It was heavy, cream-colored, with a seal of red wax—*distinctive*, not grey. And when he turned it toward the candlelight, the first line of text made his breath catch.

*To my Lady Jane, on her claim to the throne—*

He looked up at Cecil. “This is in the same cipher.”

“Then the writer either moves between households or the letters have a common author. One who knows Howard’s plot, the French ambassador’s correspondence, and your mother’s name.”

Thomas stared at the page. The pattern was unmistakable now. The same breaking of digraphs across word boundaries. The same left-dotted *i*.

He had not taught this to anyone but his father.

Which meant his father had taught it to someone else. Someone who had since turned it against everything John Finch had stood for.

Or—the thought came unbidden, cold as river water—his father had not been the only one in his family with secrets.

“I need to see Lady Jane,” Thomas said. “Not the court. The real one. The one who might not know what she’s caught in.”

Cecil’s jaw tightened. “The Queen’s household is watched. You cannot simply walk in and ask for Lady Jane Grey.”

“I’m not going to ask her anything.” Thomas folded both letters and tucked them inside his doublet. “I’m going to warn her that someone in her own circle is writing in a cipher that could hang every one of them—and that the writer knows me by name.”
