Meanwhile, Brooke returned to her apartment and began examining the notes she had collected during the previous eight months.
She had written down every conversation with Andrew, every message from Emma's friends, and every unanswered question.
One entry stood out.
May 14. Andrew said Emma had contacted a therapist before leaving. He said she was convinced people at work were stealing from the company.
Brooke remembered the conversation.
Andrew had made the claim while sitting in a café, speaking with the careful patience of a man who wanted to appear concerned rather than defensive.
He had told Brooke that Emma's suspicions were becoming difficult to manage.
"She was convinced someone was changing the invoices," he had said. "I tried to reassure her, but she wouldn't listen."
At the time, Brooke had assumed Andrew was describing an ordinary disagreement.
Now she wondered whether Emma had discovered the truth.
She called the number for Mercer Residential's former accountant.
The woman who answered had left the company the previous year.
Her name was Felicia Ward.
When Brooke explained who she was, Felicia fell silent.
"I wondered when someone would call about Emma," she said.
Brooke sat down.
"You knew something was wrong?"
"I knew she was worried."
"About Northstar?"
A long pause followed.
"Who told you that name?"
"Emma wrote it in a letter."
Felicia exhaled.
"I can't discuss confidential company information without understanding what you have. But I can tell you this: your sister wasn't the only person who noticed the inconsistencies."
"Who else noticed?"
"Daniel Price."
Brooke closed her eyes.
"He's missing too."
"What?"
"He contacted me, then disappeared."
Felicia's breathing changed.
"Listen carefully. Daniel kept copies of the payroll reconciliations. He was afraid Andrew would destroy them, so he stored them somewhere outside the company."
"Where?"
"I don't know. But before he resigned, he asked me whether a person could be held responsible for falsified accounts if they had been ordered to approve them."
Brooke felt cold.
"Did you tell him?"
"I told him to speak with a lawyer."
"Did he?"
"I think so."
Felicia lowered her voice.
"Brooke, your sister was trying to protect people. She wasn't only worried about money. She believed the records were being used to intimidate workers who couldn't afford to fight back."
"Did Andrew know?"
"Andrew knew everything that happened inside that company."
The call ended shortly afterward.
Brooke sat motionless for several minutes.
Then she opened her notebook and wrote a new heading.
NORTHSTAR: FOLLOW THE MONEY.
She added the names of Daniel Price and Felicia Ward beneath it.
At the bottom of the page, she wrote a question that had haunted her since Emma vanished.
If Emma was running away, why was she still trying to warn everyone?
That evening, Detective Ortega called.
"We've identified a possible connection between your sister's letters and financial irregularities at Mercer Residential," he said. "I can't discuss the details yet, but I need you to understand that the investigation has expanded."
Brooke gripped the phone.
"Does that mean you believe she was in danger?"
"It means we're taking the possibility seriously."
"Can you find her?"
"We're working on it."
Brooke looked toward the window.
Rain had begun falling again.
For months, she had imagined Emma alone somewhere, frightened and unable to reach the people she loved.
Now she imagined something even worse.
Emma had discovered evidence that powerful people wanted hidden.
She had tried to send it to her sister.
She had tried to reach her daughter.
And every attempt had disappeared into the same silence.
Brooke closed the notebook.
"Detective," she said, "there's something else you should know."
"What is it?"
"Andrew didn't look surprised when the letters came out."
Ortega was quiet for a moment.
"What did he look like?"
Brooke remembered the color draining from his face.
"He looked like someone who knew exactly what they were."
The next discovery came from a place nobody had thought to search.
Lily's school.
Detective Ortega visited the school counselor on a Wednesday afternoon. He had obtained the appropriate authorization to review relevant correspondence and wanted to determine whether Emma had attempted to contact her daughter through the school.
The counselor, Denise Harper, remembered Emma as a quiet but attentive parent.
She attended meetings.
She asked thoughtful questions.
She sometimes stayed after school to speak with teachers about Lily's reading assignments.
After the disappearance, Andrew had contacted the school and explained that Emma was taking time away from the family.
He asked staff to direct all family-related communication through him.
At first, the request had seemed reasonable.
Then, several weeks later, a birthday card arrived for Lily.
It was addressed in Emma's handwriting.
The card had been returned to the sender's address with a handwritten note from the office manager.
Please direct all correspondence through Mr. Mercer.
The office manager had assumed Andrew had requested the arrangement.
She had not realized that the sender was Lily's mother.
"Why wasn't this given to the police?" Ortega asked.
Denise looked uncomfortable.
"At the time, we believed the family was managing a private matter. We didn't want to interfere."
"Did you see the card?"
"No. I saw the returned envelope in the office."
"Do you still have it?"
The counselor thought for a moment.
Then she remembered that the school retained certain returned mail in a storage cabinet until the end of the academic year.
She led Ortega to a small administrative room.
Behind a stack of old attendance forms, they found the envelope.
The card itself was missing.
But the envelope had been opened and resealed with transparent tape.
The handwriting was Emma's.
The postmark was dated five weeks after she disappeared.
Ortega photographed the envelope and requested that it be preserved.
He also asked the school to provide any other records involving returned correspondence.
There were three.
One had been addressed to Lily's classroom.
Another had been sent to the school counselor.
The third had been addressed simply to the person who can help my daughter.
That envelope contained a folded note.
It was not a letter to Lily.
It was a request for help.
My daughter has been told that I no longer want contact. This is not true. I am trying to reach her safely. Please do not give my location to anyone who claims to be acting on my behalf without verifying their identity.
The note included an email address and a telephone number.
Both had been disconnected.
Ortega immediately forwarded the information to the team searching for Emma.
He also asked a digital investigator to examine the email address and determine whether it had been used to communicate with any known contacts.
The results were troubling.
The account had been created under a false name, but it had exchanged messages with a legal-aid organization specializing in domestic abuse and emergency relocation.
The organization confirmed that it had received an inquiry from a woman who identified herself as Emma.
She had requested information about protective arrangements, secure communication, and how to preserve evidence of financial misconduct.
The organization had not been able to verify her identity at the time.
The woman had stopped responding after several weeks.
When Ortega informed Brooke, she covered her mouth with both hands.
"She was trying to get help."
"Yes," he said.
"And nobody knew."
"Some people knew pieces of it. They didn't know how the pieces fit together."
Brooke looked down.
"I should have understood."
"You weren't responsible for what happened to your sister."
"I knew she was frightened."
"You suspected she was frightened. That's different from knowing what she was facing."
Brooke did not answer.
She had spent months replaying every conversation with Emma, searching for a moment when she should have recognized the danger.
The truth was that Emma had been careful.
She had hidden her fear beneath ordinary conversations and half-finished sentences. She had asked for help without explaining why. She had tried to protect people by keeping them unaware of the details.
That protection had also made her easier to isolate.
Later that week, Lily asked Brooke to visit.
Andrew had been instructed not to interfere with the ongoing investigation, and a family-services professional had arranged a supervised conversation between the sisters.
They met in a quiet room at the community center.
Lily sat on a sofa with her hands folded tightly in her lap.
Brooke sat opposite her.
For several minutes, neither spoke.
Finally, Lily asked, "Did Mom write those letters because she wanted to come back?"
Brooke swallowed.
"I believe she did."
"Then why didn't she?"
"I don't know everything yet."
Lily's face tightened.
"Dad said she didn't want to see me."
Brooke leaned forward.
"I know."
"He said she was sick. He said she needed time to get better."
"I know."
"He said if I kept asking about her, I'd make things worse."
Brooke felt a painful pressure behind her eyes.
"Lily, listen to me. Whatever happened between your parents, none of it was your fault. Your mother never stopped loving you."
Lily looked away.
"How do you know?"
Brooke reached into her bag and took out a photocopy of the letter addressed to her niece.
The original remained in police custody.
She placed the copy on the table.
"Because she wrote to you."
Lily stared at the page.
Her hands trembled as she picked it up.
