He counted three seconds after it did. I watched him do it.

“Before you pick up that phone,” he said, “you’re going to want to hear what she actually saw down there. Because you’ve got this backwards, and once you make the call, there’s no putting it back.”

My hand was on the table beside my phone. Close enough to touch. Close enough to grab.

“What did she see?”

Dennis leaned back. The chair gave a soft wooden creak.

“A man.”

I looked toward the hall. Molly’s room was at the far end, past the coat closet. Her door had stayed shut.

“A man in the basement?”

“That’s what she says.”

“You just told me I had it backwards.”

“You think I locked her down there. You think I made her keep quiet.” He rubbed his thumb along the edge of his napkin. “I didn’t. I was trying to keep her from going down there again.”

“Why didn’t you tell me there was someone in our basement?”

His mouth opened. Shut.

That part, at least, looked real.

“Because I didn’t know how to tell you without sounding insane.”

“Try me.”

“I heard him the first time on Thursday. The week before last. Molly was in the laundry room, and I was in the garage. I heard somebody moving around downstairs.”

“The basement door was unlocked.”

“Yes.”

“And you went down.”

“No.”

He said it too fast.

I picked up my phone.

“Call whoever you want,” he said. “But listen first.”

The phone screen lit my hand. Nine fifteen. No missed calls. No messages. My thumb hovered over the emergency button, then moved away. I hated him for making that tiny delay feel like a choice.

“What did you hear?”

“A chair scrape. Then three knocks.”

“From the basement?”

“From behind the basement wall.”

That should have sounded ridiculous. It didn’t. The basement ran beneath the kitchen and the old den, a square of poured concrete and exposed pipes. There was a storage room under the front steps, but no finished rooms. No second entrance. No place for a man to stand unless he was inside the furnace closet or under the stairs.

“There is no room behind the wall.”

“I know.”

“You saw someone?”

His eyes dropped to the table.

“Not clearly.”

There it was. The careful piece. The part he had been saving.

“What does that mean?”

“I saw a hand.”

Something tapped under the kitchen floor.

Three times.

Not loud. A dry little knock, close beneath my chair.

Dennis stood so hard his knee struck the table. My plate jumped. Gravy slid across the mashed potatoes.

From the hallway, Molly called, “Denny?”

“Stay in your room,” he said.

He didn’t raise his voice. That made it worse.

The knocking came again.

Three knocks.

I moved away from the table. Dennis crossed the room and took the basement door by the handle. The new lock sat above his shoulder, bright and clean. He had installed it from the kitchen side, not the basement side. I hadn’t thought about that before. The screws showed on the door. Four silver heads. New wood around them.

“When did you put that on?” I asked.

“Tuesday.”

“Why Tuesday?”

“Because she opened the door.”

“Molly did?”

“She said somebody asked her to.”

My phone buzzed. A text from Karen, asking if book club was still on for Monday. I almost laughed. The sound came out wrong, thin and wet.

Dennis pushed the lock shut.

On the other side of the door, something dragged a fingernail down the wood.

Molly began to cry.

I went to her room. Dennis grabbed my wrist.

“Don’t let her see your face like that.”

“Let go.”

“She’ll think it’s back.”

The words sat between us.

“What do you mean, back?”

He released me.

Behind him, the basement door gave a slow, soft bump.

I found Molly under her bed. She had pulled her blanket in after her, along with a plastic flashlight and the stuffed rabbit she had owned since she was three. Only one eye showed between the bedskirt and the floor.

“Honey, come out.”

“Is he mad?”

“Who?”

She pressed the rabbit’s head against her mouth.

“The man.”

“Where did you see him?”

She shook her head.

“Molly.”

“He doesn’t like when people ask.”

I lowered myself to the floor. My knees struck a Lego. Pain shot up my leg, bright and useful.

“Did he touch you?”

Her face disappeared behind the rabbit.

“No.”

“Did Denny touch you?”

She didn’t answer.

That was answer enough to make my stomach turn.

“He told me to sit still,” she said. “The first time. He said it was a test. I got up because my leg hurt, and he got mad.”

“Denny got mad?”

“No. The man.”

There was a faint blue mark on her left wrist. I had seen it that morning and blamed the monkey bars. I had kissed it while she complained about my cold lips.

“What did he look like?”

“Like Denny.”

I stopped breathing for a second.

“No. Not his face. His shirt.”

“What shirt?”

“The blue one.”

Dennis owned a blue work shirt with a torn pocket. He wore it when he fixed the fence, changed the oil, hauled branches to the curb. It had been missing since Tuesday.

I crawled backward and stood. My hip caught the desk. A cup of colored pencils tipped over, rolling red and yellow across the floor.

Dennis was waiting in the hall.

“You need to tell me everything,” I said.

“I was going to.”

“No. You were going to tell me enough to keep me from calling the police.”

“The police won’t help.”

“Try me.”

“They’ll search the basement. They’ll open the wall. They’ll find nothing. Then they’ll ask why Molly has been talking about a man who looks like me.”

“Why does she say he looks like you?”

He rubbed both hands over his face. When he lowered them, he seemed older. Not tired. Older.

“Because he does.”

Downstairs, the lock clicked.

Once.

Then again.

Someone was testing it from the other side.

“You said there was no way to open it from down there.”

“There isn’t.”

“Then who is doing that?”

Dennis looked past me toward Molly’s bed.

“The same person who has been calling her.”

“Calling her where?”

“The basement phone.”

Our old landline handset had disappeared months ago. I remembered asking Dennis about it. He had said the battery was dead and he’d thrown it out. We had kept the number because it was tied to the alarm system, though the alarm had been disconnected long before we bought the house.

“There is no phone in the basement.”

“There was.”

He walked to the linen closet and pulled out a ring of keys. His fingers shook now. Not much. Enough.

“The previous owner had a workroom down there. Behind the storage wall. We found the door during inspection, but it was sealed. The inspector said it was probably an old coal chute.”

“You knew about this.”

“I knew about a sealed door.”

“And you never told me?”

“I thought it was just old house junk.”

“You thought wrong.”

He went downstairs.

I took Molly’s hand and followed. She squeezed twice, our old signal for stop. I ignored it. I wish I hadn’t.

The basement smelled of wet cardboard and the sour dust that gathers behind appliances. Dennis switched on the ceiling light. Three bulbs came alive. One flickered.

The door under the stairs had been painted the same gray as the wall. I had never noticed the outline. Now I could see it plainly: a narrow rectangle, no knob, no hinges. The blue work shirt lay crumpled at its base.

Inside the wall, a phone rang.

Molly made a small sound and climbed behind me.

Dennis put the keys down.

“Don’t answer it.”

The ringing stopped.

Then a voice spoke through the wall.

“Mom?”

Molly’s voice.

Not a recording. Not exactly. The word came out stretched and damp, like someone copying it without knowing where the sound belonged.

My daughter buried her face in my back.

The voice tried again.

“Mom, I’m cold.”

Dennis stepped in front of the hidden door.

“Stay upstairs,” he told Molly.

“Denny, don’t.”

He looked at her. His face changed.

“What?” I asked.

“She called me that before.”

“Who did?”

“The person behind the wall.”

Something knocked from inside.

Three times.

Dennis took one of the keys and pushed it into a small hole beneath the paint. The door opened inward without a sound.

There was a room behind it.

Not a coal chute. A narrow room with concrete walls, a cot, an old telephone, and a wooden chair set facing the door. On the cot sat a child-sized figure in Dennis’s blue shirt.

Its head was bowed.

Its hands rested on its knees.

For one foolish second, I thought Molly had gone around me.

Then the figure lifted its face.

It had Dennis’s eyes.

Its mouth opened too far.

“Quiet game,” it said.

Dennis shoved the door closed. The thing struck it from inside. Once. Twice. The frame jumped.

He turned to me.

“Now you know why I locked it.”

“You let Molly play with it.”

“I didn’t know she could hear it.”

“You knew enough.”

His face folded, and for the first time since dinner he looked scared of me.

“I thought it wanted me.”

The door shook again.

Molly pulled my coat. “Mom, we have to go.”

She was right. I grabbed her and ran for the stairs.

Behind us, the lock snapped open.

We reached the kitchen. Dennis came after us, stumbling on the last step. I shoved the basement door closed and turned the lock. His hand landed over mine.

From below, Molly’s voice began counting.

“One.”

Dennis stared at the door.

“Two.”

“What happens at ten?” I asked.

He didn’t answer.

“Denny.”

“It comes out.”

“Then why are you standing there?”

“Because it only comes out when somebody breaks the rules.”

Molly’s counting continued from the other side of the door.

“Three. Four. Five.”

I pulled my phone from my pocket and called 911.

At six, Dennis grabbed the phone.

At seven, Molly stopped counting.

At eight, the basement door unlocked.

At nine, somebody knocked from inside the kitchen wall.

Three times.

At ten, the voice behind us said, “Mom?”

Molly’s hand slipped out of mine.

I caught her sleeve, but the fabric tore in my fist.

She stood beside the refrigerator, staring at the basement door.

Then she smiled at whatever was waiting there.

“I won,” she said.

And the lock appeared on the kitchen door.
