Chapter 1:KNOCK
At 2:13 a.m., Clara Vale woke to the sound of someone knocking on her apartment door.
It was not loud enough to sound urgent. That was what frightened her.
Three slow knocks.
Knock. Knock. Knock.
Then silence.
Clara lay perfectly still beneath the blanket, staring into the darkness of her bedroom. For several seconds, she wondered if she had dreamed it. The apartment was quiet except for the low hum of the refrigerator in the kitchen and the faint ticking of the clock on her bedside table. Rain had been falling for most of the night, tapping softly against the windows, and somewhere outside, a car passed along the wet street.
Then it came again.
Knock. Knock. Knock.
Clara's eyes moved toward the bedroom door.
She lived alone.
She had lived alone for eight months, ever since she moved into the fourth-floor apartment at Westbridge House. The building was old but respectable, the kind of place where people nodded politely in the hallway without knowing one another's names. There were twelve apartments on her floor, but most of them were occupied by older couples or people who worked long hours. Nobody visited her without calling first. Nobody had ever knocked on her door after midnight.
She reached for her phone.
2:14 a.m.
No missed calls.
No messages.
She hesitated before unlocking the screen. The pale light illuminated her face, and suddenly the apartment seemed much larger than it had a moment before. Every shadow looked deeper. Every corner seemed capable of hiding something.
Another knock.
This time it was followed by a voice.
"Clara?"
Her blood went cold.
She knew that voice.
She pushed herself upright, gripping the blanket around her shoulders. Her heart began beating so hard that she could hear it in her ears.
The voice came again, quieter.
"Clara, open the door."
She didn't answer.
She knew better than to answer.
The voice belonged to Daniel.
Daniel Cross.
Her former boyfriend.
The man she had spent three years trying to forget.
Clara's first instinct was to call the police, but her fingers froze over the screen. She stared at Daniel's name in her contacts. She had deleted his number months ago. She had blocked him on every social media account. She had even changed the route she took to work because there was a small possibility she might see him near his old office.
Daniel was not supposed to know where she lived.
Nobody was.
She slowly climbed out of bed and stepped onto the cold wooden floor. She didn't turn on the lights. Instead, she moved toward the bedroom doorway and stopped when she heard something scrape softly against the front door.
Her breathing became shallow.
Someone was standing outside.
She could feel it.
There was something deeply unsettling about knowing that another person was only a few feet away, separated from you by nothing more than a wooden door and a cheap metal lock.
"Clara," Daniel whispered.
She backed away.
"Please."
His voice sounded different.
Not angry.
Not drunk.
Desperate.
That somehow made it worse.
Clara pressed her hand over her mouth to keep herself from making a sound. She remembered the last night she had seen him. She remembered the blood on his knuckles. She remembered him standing in the hallway outside her old apartment, refusing to leave while she cried and begged him to stop. She remembered the way he had smiled when she told him she was finished with him.
You don't get to decide when this ends.
Those had been his exact words.
Then she had moved.
New city. New apartment. New job. New phone number.
She had told herself she was safe.
The doorknob moved.
Clara's stomach dropped.
Someone outside had just tried the handle.
She immediately stepped backward.
The handle moved again.
Slowly.
Carefully.
As if whoever was outside wasn't trying to break in.
As if he already knew it was locked.
Clara's hand trembled as she opened her phone and dialed emergency services. Before she could press the call button, the movement stopped.
Silence returned.
She waited.
Ten seconds.
Twenty.
Thirty.
Nothing.
Maybe he had left.
Maybe Daniel had finally realized she wasn't going to open the door.
Then her phone vibrated.
Clara nearly screamed.
A message.
Unknown number.
She stared at the screen.
I know you're awake.
Her entire body went numb.
Another message appeared.
Don't call anyone.
Then another.
I'm not here to hurt you.
Clara stared at those words until they blurred.
She looked toward the front door.
There was no sound.
Her phone vibrated again.
But someone else is.
Clara stopped breathing.
A second later, the lights in her apartment went out.
The refrigerator stopped humming.
The air conditioner died.
The apartment fell into complete darkness.
Clara's phone became the only source of light.
She stood frozen in the middle of her bedroom, listening.
Nothing.
Then she heard footsteps.
Not outside.
Inside.
One slow step came from the direction of the kitchen.
Clara's eyes widened.
Another step.
She hadn't heard the door open.
She hadn't heard the lock turn.
But someone was inside her apartment.
Her hand flew over her mouth.
The footsteps stopped.
Clara looked toward the bedroom doorway.
A shadow moved across the darkness.
Someone was standing in the hallway.
She couldn't see his face.
She couldn't even tell if it was Daniel.
Her mind screamed at her to run, but her legs wouldn't move.
Then the figure spoke.
"Clara?"
It wasn't Daniel's voice.
She felt something inside her break.
The stranger took one step closer.
"Don't scream."
Clara finally moved.
She grabbed the nearest object she could find—a heavy glass lamp—and held it with both hands.
"Get out," she whispered.
The figure stopped.
For a moment, neither of them moved.
Then a flash of lightning illuminated the room through the window.
Clara saw him.
Dark jacket.
Wet hair.
Blood on one side of his face.
And eyes she had never seen before.
He wasn't old. Maybe early thirties. His face was tense, pale, and exhausted, and there was a deep cut near his eyebrow. He looked less like an intruder and more like a man who had been running from something.
His eyes moved toward the phone in her hand.
"You called the police?"
Clara said nothing.
He took another step.
She raised the lamp.
"I said get out."
He stopped.
"I'm not the one you should be afraid of."
A loud crash came from the hallway outside her apartment.
The man immediately turned toward the front door.
Clara flinched.
Someone else was outside.
The stranger looked back at her.
"Listen to me carefully," he said. "In about thirty seconds, they're going to knock on that door."
"Who?"
He didn't answer.
Instead, he moved toward the kitchen.
Clara tightened her grip on the lamp.
"Don't move."
He ignored her and crouched near the counter. He pulled something from his jacket and placed it on the floor.
A photograph.
Clara stared at it.
She couldn't see it clearly from where she stood.
"What is that?"
The man looked at her.
"Proof."
Another crash came from outside.
This time Clara heard voices.
Men.
Two of them.
Maybe three.
Her fear became something physical, something she could feel crawling beneath her skin.
The stranger stood.
"I need you to do exactly what I say."
Clara shook her head.
"No."
"If they get inside, you're dead."
She stared at him.
"Who are they?"
He looked toward the door.
"The people who killed your sister."
Clara's fingers went numb.
Her sister.
Emily.
Emily had been dead for fourteen months.
The police had called it a robbery gone wrong. Someone had entered her apartment late at night. There had been a struggle. Emily had been found in her bedroom the following morning.
No suspect had ever been arrested.
No weapon had ever been recovered.
Clara had spent more than a year trying to accept that.
She had attended the funeral.
She had identified Emily's belongings.
She had watched the police close the case.
And now a bleeding stranger was standing inside her apartment telling her that the people responsible were outside her door.
"You don't know anything about my sister," Clara whispered.
The man stared at her.
"I know she didn't die because of a robbery."
Clara's eyes filled with tears.
"Get out."
"Clara—"
"GET OUT!"
The knock came.
Three slow knocks.
Knock. Knock. Knock.
Clara stopped.
The stranger looked at her.
Nobody spoke.
Then a man's voice came through the door.
"Miss Vale?"
Clara's stomach twisted.
It was calm.
Professional.
Almost friendly.
"We know you're in there."
The stranger moved closer to Clara and lowered his voice.
"When I tell you to run, you run."
Clara shook her head.
"Why should I trust you?"
"You shouldn't."
That answer stopped her.
The stranger looked toward the door.
"You shouldn't trust me. You shouldn't trust anyone tonight."
The doorknob began turning.
Clara backed toward the bedroom.
The lock clicked.
The stranger grabbed her wrist.
"Now."
She pulled away.
"Let go of me!"
The door suddenly slammed inward.
The chain caught.
A man's arm forced through the gap.
Clara screamed.
The stranger shoved the door back with his shoulder while reaching for the chain.
"RUN!"
Clara ran.
She sprinted into the bedroom and toward the window. Her hands shook as she tried to unlock it.
Behind her, wood splintered.
Someone shouted.
The stranger grunted.
Clara pulled the window open.
She looked down.
Fourth floor.
Too high.
There was no fire escape.
"There's nowhere to go!" she cried.
"Closet!"
She turned.
The stranger was standing in the doorway.
Blood was running down his cheek.
Behind him, the apartment door was beginning to break apart.
"Inside the closet," he said.
Clara stared at him.
"What?"
"There's a service hatch."
She looked toward the built-in wardrobe.
"I don't know what you're talking about."
"Your building was renovated in 1998. The old maintenance passage wasn't completely sealed."
He sounded certain.
Another impact shook the apartment.
The stranger crossed the room, grabbed the wardrobe doors, and pulled them open.
Clara saw clothes, boxes, shoes.
Nothing else.
He pushed aside a wooden panel.
A narrow black opening appeared behind it.
Clara stared.
"Go."
She hesitated.
"You're coming?"
The stranger looked toward the bedroom door.
"Not yet."
"Why?"
"Because if I go first, they'll know where you are."
The front door finally gave way.
Clara heard footsteps entering the apartment.
The stranger looked directly at her.
"Your sister left something behind."
Clara froze.
"What?"
He reached into his pocket and pulled out a small silver key.
"She gave this to me three days before she died."
Clara stared at the key.
She recognized it.
It had belonged to Emily.
A tiny silver key with a blue stone attached to the handle.
Clara had given it to her when they were teenagers.
Her eyes filled with tears.
"Where did you get that?"
The stranger closed his hand around it.
"She told me that if anything happened to her, I was supposed to find you."
Footsteps entered the bedroom.
The stranger shoved Clara into the opening.
"Go."
Clara crawled into the darkness.
"Who are you?" she whispered.
He looked at her one last time.
"My name is Noah Reed."
A man's shadow appeared behind him.
Noah turned.
Clara pulled herself deeper into the passage.
The panel closed.
Darkness swallowed her.
Then she heard a gunshot.
Clara froze.
A second shot followed.
She pressed both hands over her mouth.
For several seconds there was nothing but silence.
Then she heard Noah scream.
And a voice she recognized spoke calmly from the bedroom.
"Where is she?"
Clara closed her eyes.
It was Daniel.
He had never been outside her door.
He had been inside her apartment the entire time.
And suddenly Clara understood the message on her phone.
I'm not here to hurt you.
But someone else is.
The problem was that she no longer knew which man he had been talking about.
