By lunchtime, the rain had stopped.

The screaming hadn’t.

Detective Elias Vale stepped beneath the yellow police tape and looked up at the school’s brick walls.

Students crowded behind the barriers, whispering to one another. Teacher

s tried to keep them away from the scene, but no one could stop them from looking.

Or from wondering.

At the center of the courtyard, a white sheet covered a body.

Elias’s eyes moved away from it and settled on the words painted across the wall.

WHAT HAVE YOU DONE?

The red paint dripped slowly down the bricks.

It looked almost like blood.

“Detective Vale?”

Elias turned toward the police officer approaching him.

“What do we have?”

“Victim is Emily Carter. Seventeen years old. Senior at the school.”

“Cause of death?”

“We believe she fell from the roof.”

Elias glanced upward.

The roof was three stories above them.

“That belief based on evidence?”

“A few students heard a scream. Then they heard something hit the ground.”

“Anyone see her fall?”

“No.”

“Anyone see her on the roof?”

The officer shook his head.

Elias looked back at the message.

WHAT HAVE YOU DONE?

“Then we don’t believe anything yet.”

The principal’s office was quiet except for the ticking clock on the wall.

Margaret Holloway sat across from Elias, twisting her hands together.

“This has never happened before,” she said.

“That’s usually how murder works,” Elias replied.

Her face went pale.

“I didn’t say she was murdered.”

“No,” Elias said. “You didn’t.”

He opened his notebook.

“Tell me about Emily Carter.”

Margaret sighed.

“She was a student here for four years. Her grades were average. She wasn’t involved in many clubs.”

“Friends?”

“A few.”

“Enemies?”

The principal hesitated.

Elias looked up.

“Ms. Holloway?”

“Emily had problems with other students.”

“What kind of problems?”

“Teenage drama.”

“That’s not a kind of problem. That’s a way to avoid describing one.”

Margaret looked toward the window.

“There were rumors that Emily bullied another student.”

“Who?”

“I don’t know.”

“You’re the principal.”

“And there are hundreds of students in this school.”

Elias closed his notebook.

“Then let’s find the ones who knew.”

By the end of the day, Elias had learned one thing.

Emily Carter had plenty of secrets.

And apparently, so did everyone else.

Her best friend, Sophie Bennett, claimed Emily had been receiving threatening messages for weeks.

“I told her to go to the police,” Sophie said.

“Did she?”

“No.”

“Why not?”

“She said she could handle it.”

Elias showed Sophie Emily’s phone.

The threatening messages had been deleted.

“Who was sending them?”

“I don’t know.”

“Were you?”

Sophie stared at him.

“No!”

“Why are you crying?”

“Because she was my friend!”

Elias said nothing.

After a moment, Sophie looked away.

“We had a fight yesterday.”

“About what?”

“I don’t know.”

“That seems to be the most popular answer in this school.”

The next student was a boy named Mason Reed.

He refused to look Elias in the eyes.

“You and Emily didn’t get along?”

“No.”

“That’s interesting.”

“Why?”

“Because I have three students who said Emily made your life miserable.”

Mason’s jaw tightened.

“She did.”

“So you lied.”

“I didn’t kill her.”

“I didn’t ask if you did.”

Mason went silent.

Elias leaned forward.

“What happened between you and Emily?”

“She spread rumors about me.”

“What kind of rumors?”

“I don’t want to talk about it.”

“Then I’ll assume they were serious.”

Mason stood up.

“You don’t understand.”

“Try me.”

His hands clenched into fists.

“She ruined everything.”

Elias watched him carefully.

“And yesterday?”

“What about yesterday?”

“You saw Emily.”

Mason’s expression changed.

Only slightly.

But Elias noticed.

“I saw her.”

“Where?”

“On the roof.”

Elias leaned forward.

“Alone?”

Mason said nothing.

“Mason.”

The boy swallowed.

“She wasn’t alone.”

“Who was with her?”

“I don’t know.”

“You saw them.”

“It was raining!”

“Who?”

“I couldn’t see!”

Elias stood.

“Then tell me what you could see.”

Mason’s breathing became unsteady.

“Two people were arguing.”

“About what?”

“I couldn’t hear.”

“And then?”

“I left.”

“You just left?”

“Yes.”

“Why?”

“Because I didn’t want Emily to see me.”

“Why?”

Mason looked down.

“Because she knew what I did.”

Elias went still.

“What did you do?”

Mason slowly raised his head.

“I sent the messages.”

The room was silent.

“You threatened her?” Elias asked.

Mason nodded.

“She threatened me first.”

“With what?”

“She found out I cheated on an exam last year. She told me she’d expose me.”

“So you threatened her.”

“I never meant to hurt her!”

“Did you meet her on the roof?”

“No!”

“Did you push her?”

“No!”

“Who was the second person?”

“I told you, I couldn’t see.”

Elias studied him.

Mason was guilty.

But not of murder.

Not yet.

That evening, the medical examiner called.

Elias stood outside the school as the last police cars remained in the parking lot.

“Vale.”

“We have a problem,” said Dr. Harper.

“Those are my favorite kind.”

“Emily didn’t die from the fall.”

Elias stared toward the school.

“What?”

“She was already dead.”

The words painted on the wall suddenly felt different.

WHAT HAVE YOU DONE?

“What killed her?”

“Poison.”

Elias’s expression darkened.

“What kind?”

“Something administered within an hour before she died.”

“So someone poisoned her, took her to the roof, and threw her off?”

“Possibly.”

“Possibly?”

“There was something else.”

“What?”

“A large dose of a sedative was also in her system.”

Elias looked toward the dark windows of Westbridge High.

“She couldn’t fight back.”

“Exactly.”

The call ended.

Elias remained outside.

Someone had planned this.

Someone had poisoned Emily.

Someone had drugged her.

Someone had taken her to the roof.

Someone had made sure everyone would think she simply fell.

But why leave the message?

WHAT HAVE YOU DONE?

It wasn’t a question for the police.

It was a question for someone else.

Elias returned to the school.

Only one person remained inside.

The nurse.

Mrs. Evelyn Hart.

She was sitting behind her desk, organizing medical files.

“You’re still here,” Elias said.

“So are you.”

“Occupational hazard.”

She smiled.

“You found something.”

Elias watched her.

“Why do you think that?”

“You have that look.”

“What look?”

“The one detectives get when they believe they’re smarter than everyone else.”

Elias smiled slightly.

“And are we?”

“Not usually.”

He walked into the office.

“Emily came here yesterday.”

Mrs. Hart stopped organizing the files.

“Did she?”

“You tell me.”

“I see hundreds of students.”

“You keep records.”

“Yes.”

“Then let’s see them.”

Her smile disappeared.

“I can’t show you confidential medical information.”

“You can show it to the police during a murder investigation.”

Elias placed his badge on the desk.

“Should I get a warrant?”

For several seconds, Mrs. Hart didn’t move.

Then she opened a drawer.

“Emily came in yesterday afternoon.”

“Why?”

“Headache.”

“What did you give her?”

“A painkiller.”

“That’s all?”

“Yes.”

Elias picked up the medical record.

Emily Carter’s name was written near the bottom.

3:14 PM — Headache.

Medication administered.

Elias looked closer.

The medication was listed as a common painkiller.

“Interesting.”

“What?”

“You have a security camera in the hallway.”

Mrs. Hart looked at him.

“And?”

“It recorded Emily entering your office.”

“Yes.”

“It also recorded her leaving.”

Mrs. Hart remained silent.

“But there was a twenty-minute gap in the footage.”

Her face changed.

“Technical problems.”

“Of course.”

Elias pulled out his phone.

“The technician checked it.”

Mrs. Hart stared at him.

“He said the camera didn’t malfunction.”

Elias stepped closer.

“It was manually turned off.”

The nurse’s hands slowly tightened.

“You don’t know that I did that.”

“No.”

Elias nodded.

“I don’t.”

He placed another photograph on the desk.

It showed a small storage room.

“But I know someone cleaned the roof this morning.”

Mrs. Hart looked at the photograph.

“And?”

“The cleaning supplies came from this office.”

Her eyes moved toward him.

“You can’t prove I killed her.”

“No.”

Elias reached into his pocket and placed a small plastic evidence bag on the desk.

Inside was an empty vial.

“But this was found in the trash outside your office.”

Mrs. Hart stared at it.

“The poison in Emily’s body came from that vial.”

For the first time, she looked afraid.

Elias watched her carefully.

“Why?”

Mrs. Hart said nothing.

“Why kill a seventeen-year-old girl?”

“She was a monster.”

The words came out quietly.

Elias didn’t move.

Mrs. Hart slowly sat down.

“You don’t understand what she did.”

“Then explain it.”

“She destroyed him.”

“Who?”

“My son.”

Elias remained silent.

“Last year, my son Daniel was a student here. Emily accused him of cheating.”

Elias remembered Mason.

Emily had known everyone’s secrets.

“Was he cheating?”

Mrs. Hart looked away.

“Yes.”

“Then she told the truth.”

“She humiliated him.”

“No. His actions humiliated him.”

“You don’t know what happened after!”

“Tell me.”

Her eyes filled with tears.

“He was expelled. He lost his scholarship. Everyone turned against him.”

Elias’s voice softened slightly.

“And?”

“He died.”

The room went silent.

Elias understood.

Not enough to excuse her.

But enough to understand.

“He killed himself,” Mrs. Hart whispered. “And Emily kept telling everyone she did the right thing.”

“So you decided to kill her.”

“She had no guilt.”

Mrs. Hart’s eyes moved toward the message written in one of the crime scene photographs.

WHAT HAVE YOU DONE?

“I wanted her to feel it,” she said. “Just once.”

“You painted the message.”

“Yes.”

“But Emily was already dead.”

“I painted it for everyone else.”

Elias frowned.

“What do you mean?”

Mrs. Hart laughed bitterly.

“You really don’t see it?”

She pointed toward the school.

“Every single person here did something to her. Sophie fought with her. Mason threatened her. Students bullied her. Teachers ignored what was happening. The principal knew about the problems and called it teenage drama.”

Her voice cracked.

“Everyone had a reason to hate Emily.”

Elias looked toward the door.

“Maybe.”

“And no one did anything.”

Mrs. Hart looked back at him.

“That’s the funny thing about guilt, Detective.”

He said nothing.

“Sometimes you don’t have to kill someone to be responsible for what happens.”

The next morning, the police arrested Evelyn Hart for the murder of Emily Carter.

The truth spread quickly through Westbridge High.

Mason was charged for his threats.

The school opened an investigation into the bullying accusations.

Principal Holloway was suspended for ignoring previous reports involving students.

Sophie admitted she had known about the threats and had deleted messages from Emily’s phone because she was afraid the police would discover she had threatened Emily too.

Everyone had done something.

But only one person had killed her.

Elias stood outside the school as workers removed the red message from the wall.

For a moment, the words were still visible beneath the fading paint.

WHAT HAVE YOU DONE?

An officer approached him.

“Case closed?”

Elias looked at the wall.

“Emily’s murder?”

The officer nodded.

“Yes.”

Elias put his hands into his coat pockets.

“Then yes.”

He started walking away.

Behind him, the school continued trying to erase the message.

But some things couldn’t be washed away.

Not guilt.

Not secrets.

And not the things people did when they believed no one would ever find out.

Elias’s phone rang.

He answered without looking at the number.

“Detective Vale.”

A panicked voice spoke on the other end.

“There’s been another murder.”

Elias stopped walking.

This time, it wasn’t at a school.

It wasn’t even in the same city.

A new location.

A new victim.

New suspects.

New secrets.

Elias closed his eyes for a moment.

Then he opened them.

“Send me the address.”

The call ended.

Detective Elias Vale looked back at Westbridge High School one last time.

One case was over.

Another had already begun.

And somewhere else, someone was waiting to be caught.

End of Chapter One.
