The Door Someone Wants Locked

Cassian had a lock fitted to the door before dawn broke. The side he meant to lock wasn't the hearth room. It was Noah's bedroom. Serena asked for the key. He put it in his pocket and answered.

"I'm trying to keep him from getting hurt."

The words were true. That was what made them dangerous.

Cassian had spent the whole night thinking about the distance between Noah's hand and the golden heating coil. Two knuckles' width. One of Mara's gloves. If the bell had rung half a beat later, that distance would have been gone.

He fitted a new sheet of iron across the corridor between the hearth room and the east wing. The old door still opened from both sides, but once the iron plate was pushed shut, the handle on Noah's side wouldn't turn. The idea was to block the path to the hearth room. If there was a fire, Noah could go out the window on the other side of the corridor. The physician's assistant would bring medicine. The call cord was by the bed.

Written out line by line, it looked like a safe plan.

Nowhere in that plan was a moment when Noah might want to open the door himself.

Serena examined the iron plate in nothing but a coat thrown over her nightgown. She pressed the inside handle with her finger, then measured the distance between the call cord and the door.

"Can Noah open it from inside?"

"No."

"Orsen?"

"I open it for him."

"If you're out on the perimeter?"

"I hand the key to my deputy."

"Who confirms that you handed it over?"

Cassian didn't answer. During the war, one key had meant one person responsible. Two people responsible meant the door opened late. He knew what could happen inside a door that opened late.

"There's no time to discuss this today."

"There was time to lock it, though."

"The child went back to the hearth."

"He stopped before he touched the coil, he told us why, and we built a procedure for adult confirmation."

"Next time Mara might not be there."

"Next time you might not be there either."

The words landed square in Cassian's chest. He spoke lower.

"I'm not leaving this castle."

"That doesn't mean you get to hold the only key."

Serena laid out, one after another, Noah's stop signal, Orsen's second confirmation, the nighttime log of the open door. Cassian didn't look at the papers. A door moved faster than paper. A door that closed before a hand ever reached the coil.

"If you fail, you can just go back to the royal court."

The words left her mouth and the air in the corridor turned cold.

Serena didn't argue back right away.

"So has an outsider like me ever tried to hoard a key?"

"You hold the power to rule on dissolution."

"You hold the muscle on the ground and the doors. Checking each other is one thing. Locking a child in is another."

Cassian rested his hand on the iron plate. Under the cold metal, he thought he could hear knocking from long ago. One, two. After the fingernail broke, the sound had gotten quieter. He tightened his gloved hand.

A small sound came from inside the room.

Tap, tap.

Serena raised her head.

Cassian didn't hear it. Or rather, he took it for the latch of the iron plate catching. He kept talking, looking at Serena.

"We only need to block it once. Until the remote marker system is in place."

Tap, tap.

This time Serena knocked on the door.

"Noah?"

"Please open the door."

Cassian reached into his pocket for the key. Serena held out her hand first.

"The key."

"I'll open it."

"You still haven't let go of the decision."

"There's no time to..."

"Noah knocked twice and you didn't hear it."

Cassian's hand stopped. The iron plate hadn't blocked the heating coil. It had blocked a child's signal.

He took out the key. Serena didn't snatch it. She held her palm open and waited. That waiting was harder to bear than if she had grabbed it. Cassian let the key go.

When the door opened, Noah was sitting on the floor, not in bed. The call cord was at the head of the bed, too far to reach from the door.

"Why did you come to the door?" Cassian asked.

Noah answered simply.

"To see if it was locked."

"I was trying to keep you from going to the hearth room."

"What if there's a fire, then?"

"You go out the window on the other side..."

"What if I can't open the window latch?"

Cassian thought of the latch's height. It was above Noah's shoulder.

"I'll lower it."

"Or you could just leave the door open."

Noah didn't try to make peace between the two adults. He didn't say he'd been scared, either. He had tested whether the door would open, and remembered the answer when it failed.

Marie came down the far end of the corridor carrying a basket of medicine. One look at the iron plate and the three faces told her what had happened.

"If you lock this passage, where does the medicine go?"

"Use the stairs by the physician's quarters," Cassian said.

"Going around those stairs with the laundry adds half an hour. Did you account for that half hour of wages and the shift change?"

"It's a temporary measure."

"Temporary isn't free."

Marie held the medicine basket out to Cassian.

"You carry this morning's medicine yourself. Waiting on a locked door isn't part of my job."

She didn't wait for Serena's instructions. She wrote the width of the laundry cart and the turnaround time in chalk under the iron plate. It was proof that not just Noah's freedom of movement, but the paths for medicine, soup, and laundry too, had all been trapped behind one door.

Cassian took the medicine basket. The cost of his own plan had just gone up by the weight of two hands.

At noon, an open key board was mounted on the wall outside the hearth room. Serena wrote the new rules in three lines.

No locking by a single person. Noah and a second adult must be able to open it from either side. If a lock is needed, the reason, start time, end time, and the holders of both keys must be posted.

Cassian added a line underneath.

Whoever locks it must personally test that it works before the next shift, but must not enter the room to do so.

"Why not enter the room?" Serena asked.

"If the person testing it is inside, they can pass their own plan with their own key."

It was an accurate correction. It wasn't an apology.

Noah saw the two keys. One hung on the open board, the other on a low hook inside his bedroom.

"What if I knock twice?"

"The door opens first," Cassian said. "The reason comes after."

"What if you don't hear it?"

"The corridor watcher knocks the board. The second adult is Orsen."

Noah didn't nod.

"Let's try it today."

Cassian didn't try to talk the boy into it. He took the iron plate off entirely and put handles back on both sides of the original door. In the first test, Noah's key hook was mounted too high. Even standing on his toes, Noah's fingers only scraped air below the hook.

"We'll put a chair there," Cassian said.

Noah dragged a chair over and climbed up. The hem of his nightgown caught on his legs and he had to brace one hand against the wall.

"If there's smoke, do I look for a chair first?"

Cassian removed the chair immediately. He lowered the key hook to Noah's waist height. When he went to hammer in the nail, Marie passed by pulling the laundry cart and said,

"Mount it there and it'll catch on the cart handle."

"It's on the inside of the door, though."

"So is where the medicine basket sits. You carried it yourself this morning."

Cassian pulled the nail. The left side of the doorframe was where the cart passed, and the right side was the wall Noah gripped when coming from the bed to the door. He asked Noah,

"Which side is easier to reach?"

Noah touched the low post on the right.

"Here. But if the cord is too long, it'll catch my foot."

Cassian tied the key to a short leather cord and checked three times that Noah could pull it free with one hand. The first time, the knot was too tight and it wouldn't come loose. The second time, the key struck the wall with a loud clatter. Only on the third try did it reach the handle in one motion.

There was a failure on the corridor side too. Noah knocked twice from inside, but Orsen couldn't tell it apart from the sound of the medicine basket being set down. Marie hung an empty brass bowl beside the door. If the corridor watcher heard the signal, they would strike the bowl once and raise a white card.

"If there's too much noise, you'll miss it again," Serena said.

"That's why we only strike it once," Marie answered. "Two knocks is Noah's signal, one strike is the answer that we heard."

They tested it again. Noah knocked twice from inside, the corridor watcher struck the brass bowl once, and Orsen opened the door from the other side. At the same time, Noah turned the inside handle with the key from the low hook.

The door opened from both sides. Cassian never touched it.

On the test log, before the word "success," there were entries for hook height failure, knot failure, sound confusion failure. Serena added that the same test would be repeated the next day at the same time with a different watcher.

After the test ended, Serena asked.

"Why did locking the door come first?"

Cassian looked at the extinguished hearth in the room beyond. The smell of metal and wet ash hung together. His left hand, inside the glove, went numb.

"Noah could have gotten hurt."

"That's the result. I'm asking why locking was the only thing you saw."

"It's not something I need to explain."

"Then you'll put up the same door the next time you're afraid."

Instead of answering, Cassian signed his name under the key board. No locking alone. Two-person confirmation. The child's key. The end strokes of his handwriting dug deeper into the paper than usual.

Serena checked the signature but didn't say she forgave him.

"I'll accept the rule. I'll judge trust after it's been tested."

"For how long?"

"Until the next time you're afraid."

Cassian's first sentence grew long and then swallowed its own end.

"By then, will you still be..."

He couldn't ask it. Asking an outsider who was meant to leave whether she would stay felt like demanding a promise to remain in exchange for handing back a key.

Marie took the iron plate away, saying she'd use it as a stand for the laundry cart. "Better for drying cloth than for blocking doors." She looked at his soot stained gloves and held out her hand.

"Those need washing."

Cassian stepped back.

"I'll do it."

Near the cold hearth, his hand gripped the glove tighter. Marie didn't force it off him.

"Then put your name on the laundry sheet. Don't hand it off to me as night work."

Cassian did.

When he hung the key on the open board, a bit of old black powder fell from the fingertip of his glove. Unlike the coal dust from that morning, it was fine soot. On the ash covering the floor, a single short mark remained, starting at about a child's eye level. The same height mark showed faintly on the inner wall of the hearth too.

Serena saw it, but she didn't call it a name. Cassian didn't explain it either.

The door opened. There were two keys now. Even so, Noah slept that afternoon with his feet turned toward the door, and Serena left a blank space beside Cassian's name on the next shift verification sheet.

The second key stayed right where it was, on the low hook inside Noah's door.
