Anna stood beside the back door with one hand on the lock and the duffel pressed against her leg. The front handle moved once. She pictured Dererick entering, seeing the packed bag, and understanding everything in a single glance. Her plan reduced itself to one action: unlock the door, cross the yard, climb the fence if necessary, and reach Mr. Peterson.
Then came three quick knocks.
Anna recognized the rhythm.
“It's me,” Clare called softly.
Anna nearly collapsed.
She opened the front door only far enough to pull her sister inside. Clare wore hospital scrubs beneath a coat, her hair twisted into an untidy knot, exhaustion visible around her eyes. She looked at the duffel, then at Anna.
“You're coming with me.”
Anna handed her the duplicate drive.
“First look at this.”
Clare did not want to. Anna could see it in her face. Her sister had arrived expecting a frightened woman who needed removing from danger, not an expanding investigation. But when Anna showed her the photograph of the notebook page containing Clare's name, the argument ended.
Clare enlarged the image on the phone.
“That's my workshop.”
“You remember it?”
“Of course. It was at the wellness center.”
“Did Dererick go?”
“No.”
Anna pointed to the notation beside Clare's name.
“Then how did he know?”
Clare stared at the screen.
A memory surfaced slowly. At the workshop she had met a man who said he knew someone from the hospital. He had been friendly, unremarkable, interested in the group’s schedules because he claimed to be organizing another event. Clare had given the interaction almost no thought.
Now both sisters wondered whether it had been accidental.
Clare's professional composure returned quickly. “We take this to the police.”
Anna nodded, but she wanted something else first.
“There's a neighbor who knows he's been leaving at night.”
“Who?”
“Mr. Peterson.”
They crossed the street together.
Peterson listened while Anna described the notebook. When Clare showed him the photograph containing her name, his face tightened. He admitted that Dererick's nighttime habits had become stranger over the past several months. Certain cars appeared briefly after midnight. A delivery vehicle sometimes stopped without leaving packages. Peterson had once seen a man in a dark hooded sweatshirt waiting near the communal mailboxes and assumed he was meeting someone.
“Could you write down what you remember?” Clare asked.
Peterson nodded.
“Dates if you have them.”
“I keep calendars.”
He disappeared inside and returned with an old desk diary. Several dates contained brief notes about vehicles, deliveries, and unusual activity. Peterson had recorded them because he complained regularly about parking and late-night noise.
Anna almost laughed from relief.
The eccentric habit that neighbors teased him about had produced an independent timeline.
Peterson handed Anna a small penlight. “If you're going searching around in dark rooms, stop using your phone flashlight. It announces you to half the street.”
Clare frowned. “She isn't going searching anywhere.”
Anna accepted the penlight.
“I agree with your sister,” Peterson said. “But I also know that telling a determined person not to do something doesn't always stop them.”
Clare looked between them. “Wonderful. I've arrived at a conspiracy.”
For a moment, despite everything, Anna smiled.
It lasted only seconds.
They returned to the house to make one final copy of the evidence. Clare stayed near the front window while Anna worked. Together they created a simple inventory: photographs of notebook pages, copied folders, timestamps, images of the camera, and a written account of what Anna had witnessed at 2:17 a.m.
Clare insisted that Anna write the account immediately while the sequence remained clear.
“Don't interpret,” she said. “Describe.”
Anna understood. She wrote down exactly what she had seen: gloves, black case, camera, vials, syringe, spoken references to timing, and Dererick's behavior when her foot moved.
When she finished, Clare read the statement once.
“This is what you tell investigators.”
“You believe me?”
Clare looked up sharply.
“Anna, I believed you before I saw the files.”
The answer hurt more than doubt would have, because Anna realized how badly she had needed to hear it.
They placed one copy of the evidence in Clare's hospital bag. Anna kept another. A third remained hidden in the house. Peterson agreed to store a fourth if necessary.
Clare wanted Anna to leave immediately.
Anna was about to agree when her attention returned to the flash drive.
Several folders remained unopened.
“We don't know what those initials mean.”
“We don't need to know today.”
“What if they're people?”
“Then investigators can find out.”
“What if investigators decide there isn't enough to investigate?”
Clare had no immediate answer.
Anna had already imagined that possibility. Dererick was respected. He was composed. He had explanations for everything. A camera could be described as a sleep-monitoring device. Medical supplies could have legitimate purposes. A notebook could be called fiction or research. Unless the files clearly established what he was doing, Anna feared authorities might treat the entire situation as a troubled marriage.
“Ten minutes,” she said.
Clare hated the compromise, but agreed.
They opened the copied drive rather than Dererick's original.
The first folder contained photographs of people entering cafés, offices, apartment buildings, and parking lots. Some appeared unaware of the camera. Others were screenshots from public social-media posts.
The next folder contained notes.
Dererick had recorded routines with obsessive precision: when people left for work, where they bought coffee, which nights they exercised, whether they lived alone, who visited regularly.
Clare leaned closer.
“This isn't normal.”
Anna said nothing.
A spreadsheet contained categories. Anna could not understand all of them, but several headings were unmistakable: introduction, observation, access, response.
The language made people sound like projects.
They opened another folder.
This one contained recordings.
Anna played only a short segment. Dererick's voice spoke gently to a woman Anna did not recognize. He asked about work, insomnia, loneliness, and whether she had anyone nearby who could help if she became sick. His manner sounded compassionate.
Then Anna saw the accompanying notes.
Dererick had analyzed the conversation afterward. He recorded which questions produced personal information, which expressions encouraged trust, and what he should try during their next interaction.
Clare pushed her chair backward.
“He rehearsed being kind.”
Anna understood exactly what she meant.
Dererick had not merely exploited trust after receiving it. He had studied how to manufacture it.
They continued.
One folder contained references to substances and quantities. Another included photographs of small containers resembling the vials Anna had seen beside the bed. Dates matched some entries in the notebook.
The evidence did not tell them everything. It told them enough.
Anna was one subject in a larger pattern.
Clare searched for her own name. Nothing appeared directly, but the yoga workshop surfaced in a set of notes concerning social connections. Dererick had mapped relationships outward from people he already knew.
“He was looking through networks,” Clare said.
“Friends of friends.”
“Family.”
“Neighbors.”
They looked at each other.
Mr. Peterson.
Anna closed the laptop.
They crossed the street again and warned him not to accept food, drinks, packages, or unexpected visitors connected to Dererick. Peterson listened without protest. Then he told them something he had not mentioned earlier.
Two nights before Anna discovered the camera, Dererick had asked him an unusual question.
“He wanted to know whether my porch camera recorded your driveway.”
Anna felt the temperature inside her drop.
“What did you say?”
“That it mostly points at my steps.”
“Does it?”
Peterson gave her a thin smile.
“No.”
His camera captured part of Anna and Dererick's driveway.
They reviewed the footage.
There he was.
On multiple nights Dererick left the house carrying the black case. Sometimes he drove away. Sometimes he returned within an hour. On one recording he met another person beside a parked vehicle. The image was too distant for identification, but the exchange was visible.
Clare immediately copied the relevant clips.
For the first time, they possessed evidence Dererick had not created himself.
Peterson's recordings could independently establish his movements.
Anna felt the investigation shift beneath her feet. Until then, everything had originated inside Dererick's private world. He could claim fabrication or misunderstanding. Peterson's camera introduced an outside witness.
“We go now,” Clare said.
This time Anna did not argue.
They planned to leave the neighborhood separately. Clare would take the main road. Peterson would watch for anyone following. Anna would carry only one copy of the evidence so that losing her bag would not destroy everything.
Before leaving, Anna returned home alone for less than five minutes.
She moved through the rooms with the penlight in her pocket, although daylight filled the house. Everything looked exactly as it had that morning. The couch. The half-read book. The kitchen towels. The teapot.
She stopped beside the sink.
For weeks Dererick had stood there preparing her nightly drink.
Anna opened the cabinet where the tea was stored.
Behind the box of chamomile sat a small container she had never purchased.
She did not touch it.
She photographed it.
Then she noticed a second item pushed farther back: a packet with a shipping label partially removed.
Anna photographed that too.
A sound came from the front of the house.
She froze.
Nothing followed.
Anna reminded herself that old houses made noise.
She turned to leave.
Then she saw the study door.
It was open.
Anna was certain she had closed it.
She stepped closer.
The locked drawer containing Dererick's notebook was slightly pulled out.
Her heartbeat accelerated.
She checked beneath the desk.
The key was gone.
Anna did not need to open the drawer.
Someone had been there after her.
She backed away.
Her phone vibrated.
A message from Clare appeared.
GET OUT NOW.
Anna grabbed the duffel and ran through the back door.
She crossed the yard and reached the alley without looking behind her. Only when she arrived at Peterson's garage did she stop.
Clare was waiting beside her car.
“What happened?”
“The drawer.”
“What about it?”
“Someone opened it.”
Clare's face changed.
“Dererick?”
“I don't know.”
Peterson emerged from his back gate carrying his diary.
“I saw a car stop near your house twenty minutes ago,” he said.
Anna stared at him.
“Whose?”
“Didn't recognize it.”
“Did someone go inside?”
Peterson hesitated.
“Yes.”
The three of them stood silently.
Dererick was supposed to be at work.
Anna thought of the unknown figure beside the vehicle in Peterson's nighttime recording, the correspondence on the drive, and the notes that treated people as projects.
For the first time, she considered a possibility more dangerous than her husband acting alone.
Someone else might already know she had begun looking.
