Well, that would be a much more unfortunate position.

Cyprian put a hand on Radu’s shoulder. “You have nothing to fear.”

Radu could not agree with that.

Constantine, just like the city he ruled, was not what Radu had expected. He was older, nearer to fifty than forty. His hair had thinned on top. In place of an elaborate crown, he wore a simple metal circlet on his head. Though every other man adhered to the fashion of layers, the emperor did not follow suit. His white shirt and purple breeches were simple, even austere. He seemed utterly devoid of pretense.

What a luxury honesty was.

Radu and Cyprian stood at the back of the crowded room. Constantine paced near the front, his tall, thin body leaning into the movement so that his head led the way with every step. With a start, Radu realized the emperor’s feet were bare. He stifled a surprised laugh at the absurdity of the emperor of Rome walking around without even stockings.

“What of the Golden Horn and the seawall?” the emperor asked.

“We have nothing to fear there,” a man said, waving dismissively. He was tall and broad, his body a blunt instrument of war. “A handful of poorly trained ships against my Italian sailors is nothing. We are perfectly safe on the seawall.”

Radu saw his opportunity. Telling Constantine the truth, and about something easily confirmed, would solidify his status. Knowing what they faced would not magically replace the seven ships that had already fled, or line their walls with men that were not coming.

“You are not safe there,” Radu said. Every face turned to him with curiosity. “When I left, Admiral Suleiman had six large galleys. Ten regular. Fifteen small. Seventy-five large rowboats for transporting men and navigating small spaces. Twenty horse transports.”

The change in the air was palpable. “Who are you?” the Italian man demanded.

“Radu of—” Radu paused, again not knowing what name to give himself. “Radu most recently of Edirne, where I served at Mehmed’s—the sultan’s—side these last several years. Most particularly overseeing the secret development of his navy.”

Cyprian put a hand on Radu’s shoulder. “This is the man who saved my life, Uncle.”

Constantine pointed at a man near the door. “Send word to the governor of Galata. Tell him we are drawing the chain across the horn to block all entry.” No one moved. “Now!” he shouted.

The man stood, bowing, and ran from the room.

“Is that to be his main point of attack, then?” Constantine asked.

Radu shook his head. “He means to press you on all sides. If he can get through on the seaward side, he will. But his focus is the land walls.”

“The walls will stand,” a priest said. “They have always stood. They will always stand.”

“They have always withstood attacks before, but attacks change,” Radu said. “The sultan spares no expense on new methods and weapons. He has studied the walls, has even been here in person. He means to focus on the Lycus River Valley and the section outside the palace.”

A man near the front frowned. He wore clothes closer in fashion to the Ottomans than to the Byzantines. “Those are obvious choices. We already know this.”

“Orhan is right,” the Italian man said. Radu startled, looking closer at the oddly dressed man who had just spoken. Orhan was the false heir to the Ottoman Empire—a man whom Constantinople had used to threaten Mehmed’s rule since before it began. Even now, Mehmed had to send money periodically or else Constantine would send Orhan into the empire to stir up civil war.

Orhan had been and was an actual, active threat to Mehmed’s life. Anger flared in Radu’s heart. He wanted something to hurt these people, to make them feel the fear they should. “He has artillery.”

“We have seen artillery!” a portly man shouted. “So he throws some stones. Our stones are bigger.” Laughter echoed through the room. Encouraged, the man continued. “The Ottomans have never had stones as big as ours.”

Radu offered a tight smile in response to the man’s dirty bravado. “They have a cannon four times my height that can shoot a six-hundred-pound ball over a mile.”

No one laughed at that, though several scoffed visibly. Constantine sighed. “We may as well bring in food. And I hope someone is writing all this down?” He gestured for Radu to take an empty seat nearby.

Radu sat. He was in, for good or ill.

Constantine looked at the ceiling as though an answer were there. “What if we relinquish Orhan’s claim?”

Radu looked at the pretend heir. Orhan stared down at his hands, which were soft and pale. Not warrior’s hands, like Constantine’s or the Italian’s. Orhan nodded.

Constantine reached out and squeezed the other man’s shoulder. “We release any threat against Mehmed’s legitimacy. We graciously decline payment for the land the Rumeli Hisari is built on. We increase our payments to him.”

Radu wondered if he should encourage that. Perhaps Mehmed would want it. But he would still attack. And everything here would be Mehmed’s in the end, so it did not matter. Radu would tell the truth. “His mind is set on the city with a singular focus. He has spoken and dreamed of little else since he was twelve. I do not think anything will deter him now. You can offer, but short of surrender, you should prepare for siege.” Radu dared to hope that after hearing his tales of men and cannons, they would surrender. He could deliver the city, unharmed, directly to Mehmed!

Constantine turned to the Italian, eyebrows raised expectantly. “Giustiniani?”

Giustiniani’s Greek was heavily accented, but he spoke with a command and even a joviality that demanded confidence. “We are nearly settled, your grace. We stretched your purse as far as we could. All the food and water is stored. We have enough to last for a year, with minimal supplementation.” He smiled bitterly. “There are advantages to so many leaving, after all.”

Radu wilted inside. No easy surrender, then.

Giustiniani continued. “We may be outmatched in artillery, boats, and men—overwhelmingly outmatched in men—but rest assured, Constantinople is still the best-defended city in the world. It will not fall easily. Tell me, Radu: do you think we can outlast Mehmed?”

Radu weighed the truth. Surrender was not on their minds yet. And they were right to make an effort. Even speaking the words felt disloyal, but acknowledging reality would not change it. “If you can draw out the siege long enough, you have a chance. The Ottomans have come against Constantinople before, and they have always failed. They are superstitious; they will see portents of doom in any delay or failed initiative. Mehmed will be fighting time and morale. He is better prepared than anyone who has ever come before, but he is betting his throne and his legacy on this single assault. If you can outlast him, he will never be able to amass the support to make another attempt.”

“So if we do this, the city is safe from him.”

Radu nodded. “I do not doubt that if Mehmed fails at the wall, he will not live long afterward. There are too many powerful men who do not like him.” The thought terrified Radu. Halil Vizier was still with Mehmed, working against him at every possible turn. How could Radu protect Mehmed from here?

Constantine stared blankly at the floor, his expression far away. “All we have to do is outlast him, then.”

It was as simple and as impossible as that.

Late March

“WHERE ARE YOU going?” Bogdan asked.

Lada whipped around, knives in her hands. Taking a deep breath, she put them away. It was near midnight. She had thought her furtive exit from camp would go unmarked. She should have known Bogdan would mark it, as he did all her movements. He had a way of tracking her, watching her without watching. His childhood loyalty had grown as broad and strong as he had. Usually Lada found comfort in that. But lately it felt far more serious, like he was not only looking for her but also looking for something from her.

She had been deliberately vague about their purpose on the shared border of Hungary, Transylvania, and Wallachia. None of her men had questioned her disobeying Hunyadi’s directive and leaving the Transylvanian passes they were supposed to guard.
