Princess Hazelyn needed one spy she could trust, and she had none. She stood in a cold storeroom beneath the castle, far from the throne she had left behind. Her lavender gown dragged through brass dust. Her tiara felt heavy and useless here. Ethen carried his whole cause alone, and she meant to build him a hidden order of loyal eyes and ears. But a single wrong recruit could sell him out and end everything. For three nights she had watched candidates slip through this room. Not one had proven safe. Tonight she tested the last one. She set out a false letter on a crate, sealed with a forged mark. It named a secret meeting place and a time. If her recruit carried the lie to an enemy, she would know. If he kept it quiet, she could trust him. The door creaked. A young grey tabby cat padded in, clockwork parts clinking in the small pack on his back. His cinnamon eyes found her at once. "You left that letter where anyone could grab it," Ramen Wandercog said. He did not touch the crate. "Sloppy. Or a trap." Hazelyn kept her face still. "Read it." He lifted the letter, scanned it, and set it back down exactly as he'd found it. "This meeting place is wrong. The seal is wrong too. The real mark has seven gears, not six." He tapped a gear on his chest strap. "Whoever you're testing, Princess, you should test them with something true. A lie this clumsy only catches fools." Her heart jumped. He had spotted the trap and refused the bait. He had not run to tell a soul. Instead he had come straight back to warn her. "How did you know the seal?" she asked. "I fix things. Locks, letters, old engines." He shrugged, and a spring in his pack chimed. "I notice when parts don't fit. Yours didn't." Hazelyn crossed the room and took the false letter from the crate. She tore it in half. "I was not testing someone else," she said. "I was testing you." Ramen's ears flattened, then rose. "And?" "You passed." She held out her hand. "I serve Ethen's cause. He thinks he stands alone. I am building people who will stand with him, in secret. I need someone who sees what others miss. I need you." He studied her hand a long moment. Then he shook it, his paw small and cool against hers. "I'm in," Ramen said. "But a spy who works alone gets caught. One recruit isn't an order. We need more, and we need them fast." Hazelyn nodded. He was right. She had her first loyal recruit at last. Now she had to find the rest before Ethen's enemies found them first.

Three days after Hazelyn recruited Ramen, the news reached her in the castle's clock tower. She climbed the brass stairs with her gown bunched in one fist. Ramen waited at the top, his pack ticking fast. He held a torn strip of paper. "One of our coded messages got out," he said. "Ethen's enemies took it. I don't know how much they can read." Hazelyn's stomach dropped. The message named her first agent and where he would move next. If the enemy had cracked the cipher, that agent walked straight into a trap. She needed to learn what they knew, and fast. "Can you break their copy?" she asked. "No," Ramen said. "But I can watch who reads it." He tapped a gear on his strap. "Letters pass through the castle's mail drop below the great clock. If an enemy hand touches it, I'll see." They worked through the night. Ramen rigged a thin wire to the brass mail chute, weighted so it would trip when a package passed. Hazelyn crouched beside the iron pipes that ran along the wall, listening. Steam hissed through them. Her tiara knocked against a valve, and she shoved it into her pocket. A princess hiding in a chute was no princess at all. Near dawn the wire sang. A gloved hand pushed a folded message into the chute. Ramen snatched it before it dropped. He read it by the light of a glowing dial. "They have our cipher," he whispered. His cinnamon eyes went wide. "Half of it. They know the agent's name. They don't know the meeting changed to the lower gate." Hazelyn breathed out. The enemy knew enough to kill, but not enough to catch them both. "Then we move the agent to the lower gate tonight," she said. "We let their trap close on empty air." Ramen grinned. "And we feed them one more lie. Make them think the old plan still holds." He copied the enemy's message in the same hand. Hazelyn changed one line, naming the wrong hour. Ramen slid it back down the chute. They watched the gloved hand return and take the bait. Below, boots gathered at the empty meeting place long after her agent had already passed through the lower gate, safe. By morning Hazelyn stood beneath the great clock, its hands grinding above her. Her agent was alive. But she had learned something colder than relief. Her cipher was half broken, and the castle itself held an enemy who moved its mail. "We can't trust the old code anymore," she told Ramen. "We build a new one. And we find who wears that glove." Ramen nodded. "An order needs secrets no one can steal," he said. "I'll start tonight." Hazelyn pulled the tiara from her pocket and did not put it on. She had saved one agent. Now she had to protect every agent still to come.
