One of the men managed to hit her a good one across the back. Then the other man moved in. She got away, scrambling up over a pile of boxes. They chased her. Once, she tripped longwise and didn’t roll away fast enough and got herself kicked in the belly.

Around the edge of the yard, a dozen boys did nothing . . . Hawker squinted into the eyepiece. No. That was probably girls and boys. Hard to tell from here.

Five minutes. Ten. Eventually it stopped. The men backed away. The girl struggled back to her feet and leaned over, arms braced on her thighs, braids falling straight down to brush the backs of her hands.

The two men motioned another kid over and began the creative process of beating the hell out of him in a purely instructive way. The girl limped to join the group lined up along the wall. It made him hurt, just looking at her.

He glanced across at Owl. “Some men take their pleasure in strange ways. Is that what you brought me here to see?”

“Yes.” She held her hand out for the field glasses, wrapped them up carefully in a checked cloth, and gave some attention to settling both pairs, and the gun, neatly in the basket. “What do you think?”

I think there’s men better dead. “She’s a nimble little thing.”

“She has been in training for a few years, I would think. She is good at fighting. Today, they are being taught that one may be hurt and hurt and hurt again and still continue. It is a valuable lesson. Those men, the Tuteurs who rule that house, repeat it frequently. Let us go. Someone might possibly look up and see us in this tower where we have no business being.”

“Who are they?” He stepped in front of Owl, blocking her way. Not touching. A man risked whatever part of his body he laid on Owl, careless-like.

She looked away from him, down into the spiral of descending dark in the opening of the trapdoor. “They are called the Cachés. The hidden ones. They are being groomed to be sent to England.”

With the last words, she went off down the stairs, as if she’d said everything that needed saying.

Since he knew a fair amount about women, he didn’t hurry. He came along slowly after her, counting steps so he didn’t trip at the bottom, hearing her footsteps in front of him. At the bottom of the steps he could see the outline of the door. Owl was blocking off some of the light at the lower edge.

If he’d been waiting there, he’d have stood off to the side so he didn’t give away where he was. Lots of tricks Owl didn’t know yet.

He took the last few steps and reached past her to spread his hand flat on the door before she opened it. “What do you want from me?”

She whispered, “We will talk outside. I—”

“We will talk here. Explain, or I walk out and leave you.”

She made some gesture he felt in the air. “You bluff. You will not walk away after what you have seen. You have no choice but to listen.”

“You’d be amazed what kind of choices I have.” He opened the door an inch.

Her fingers touched his arm. “Wait.” It was enough to stop him.

He was looking at a smooth, pretty face that didn’t belong to a child. Determined eyes. Eyes that suggested it was probably not a good idea to cross her. He didn’t know what she saw when she looked at him.

She stood and breathed on his shoulder long enough to make a warm, damp spot. Then she spoke, low and fast. “That place is called the Coach House. They made carriages there, years ago, in the work building behind the courtyard. There is a school now in the house where the master once lived.”

“A damn strange school if you ask me.”

“When one considers its purpose, it is not so strange.”

“Are we going to stand here and play guessing games? Spit it out or swallow it.”

“I am deciding what you should know.” A moment passed. “I take a great risk. In all of Paris, there are no more than a dozen people left who know the Coach House exists and what happens there.”

“Well, I’m not one of them yet, am I?”

“That is because you are an imbécile and keep interrupting me.” Another minute passed. “They are orphans, those children. A man of the Police Secrète searches for young orphans of a particular quality.” The long slit of light from the door fell on her face. Her mouth pulled in at the corner. “There have been many orphans in France, since the Revolution.”

“They’re a glut on the market lots of places.” The streets of every city ran full of strays in various stages of starvation. He knew. He’d been one. “Common as lice.”

“These children are not so common. They are the clever ones. Some are so beautiful they make the eye ache. They are brought there at eight or nine or ten years and it begins. In that house, every spoken word is English. They eat English food and learn the lessons and games of little English schoolchildren. You would not know they were born French. They are trained to fanatic loyalty to France and to the Revolution. Then they are sent to England, to be spies.”

Interesting. “Not much use sending kids that age, if you ask me.”

“You say that, you, who are younger than many of them. I would be amused if I had leisure to be amused with you.” She shook her head. “Think, ’Awker! Someday, they will not be children. They will be grown men and women who have worked their way into the circles of power.”

“That’s planning a long time ahead.”

“We speak of the Secret Police. Twenty years is a nothing. Governments rise and fall, but the Police Secrète remain.”

“And that is a thought to take home and have bad dreams about.”

“Do not smile at me in a superior manner. We speak of dangerous matters here, not foolery.”

“I’m listening.”

“Probably not, but I will speak anyway.” She bent her head closer and lowered her voice to a whisper. “The children are reborn in the Coach House. The Tuteurs strip away from them all they have, even their names. When a place is found for them, they are sent to England and pass as orphans, or as children lost from English families. They are so young, no one questions whether they are what they appear to be.”

That was a satchel of news to bring home to Doyle. Kids planted in England, waiting to be let loose someday. Spies still in the pod. “You know a lot about it.”

“It is part of my charm to be knowledgeable in many fields.” She batted his arm. “Move aside. I want to go out into the light to speak of this.”

He didn’t budge. “Why did you bring me here?”

“We will put an end to this. You and I. Tonight.”

He said a couple of French words he’d learned recently. He wasn’t sure what they meant, but it was something obscene. “Don’t tell me your people couldn’t have stopped that, Chouette. Any day. Any week. If you gave a damn about—”

Her hand twisted into the cloth of his coat. She held him, furious, snarling into his face. “We did not know.”

“You knew.”

“Écoute-moi, Citoyen ’Awker. You are the newly minted spy. You strut about with your insouciance and your black knife and you understand no more than a flea. This is the battle of shadows we fight here in Paris. There are a hundred factions. There are secrets the Secret Police themselves do not know. Men too powerful to be challenged.” She let go of him. Pushed him away. “The Tuteurs who rule the Coach House were such men. They were untouchable.”

She stood, breathing heavily, her teeth gritted. If he kept quiet, she’d get to the rest of it.

She did. “Three days ago, the Head of the Coach House followed Robespierre to the guillotine. Now, secrets creep into the daylight. Men say openly that the Tuteurs of the Coach House have committed the most evil acts.”

“What exactly does that mean when you put it in plain words? Being as I’m an expert in evil, I take a certain interest in the variety of depravity in this—”

“Do not play the dunce. You are not the only connoisseur of evil here. We have all waded deep in blood since the Revolution.” Her voice was brittle as glass. “You may accept my judgment. The men who placed those children in England were monsters. They have committed enormities. The Secret Police themselves are appalled.”

“What enormities?” When she didn’t answer, he said, “Go ahead. Name them. Impress me.”

She set her fist to the wall. Just set it there and looked at it. “Many of the Cachés—most—became children built of smoke. False names and false histories. English children who never existed. But some were more solid than that. Sometimes, the Tuteurs traded a child for a child.” She hit the wall, suddenly, with the side of her fist. It must have hurt. “Stand aside. I will go out from here. I am sick of darkness.”

He let her shove him away. When he followed her outside, she was waiting for him at the iron railing that separated the churchyard from the road, holding onto one of the bars with her free hand, looking at the ground.

He said, “Now you tell me what that means. A child for a child? What’s that?”

She breathed deeply. Twice. “Sometimes, the Cachés became real English children. They became orphans without close family, sent to live with distant relatives.” She let go of the railing. “How do you think so many very convenient orphans are created? Walk beside me. I must tell you what we will do tonight.”

“Hell. Are you saying . . . ?”

“I am not saying anything. Now, attend.” She strode down the street, every bit of her the firm, busy, basket-on-her-arm house servant. A kitchen maid in a hurry. Not one speck of spy showed. “These Tuteurs must close that house if they wish to avoid an accounting for what they have done. They must place the last children in England, and do it quickly and brutally. I will not allow this.”
