Anna did not sleep after seeing the photograph of her house. The four words beneath it—You missed one file—kept returning with the maddening rhythm of a dripping faucet. The message could have been bait. Morales said as much. Someone who understood that Anna had copied Dererick’s archive might be trying to lure her back into the house, force a mistake, or make her distrust the evidence already in hand. Yet another possibility was harder to dismiss. If the sender truly knew the structure of Dererick’s files, then the message might be accurate.
Morales took Anna’s phone and documented the message before asking whether any folder, device, drawer, or storage location had seemed incomplete. Anna went through the study in her mind: desk, locked drawer, flash drives, notebook, computer, tea cabinet. She remembered Dererick’s black case but had never searched it. She remembered the camera beside the bed, which he had removed before dawn. She remembered labels on vials she had been unable to read. None of those felt like a “file.”
Clare sat across from her with both hands around an untouched cup of hospital coffee. “Maybe they mean a digital file.”
“Or a physical folder,” Anna said.
“Or nothing at all,” Morales replied. “Do not let an anonymous sender choose our next move.”
Anna appreciated the caution, but the message had changed the shape of the problem. Whoever had sent it knew she had copied enough of Dererick’s material to notice what was absent. That suggested access deeper than casual acquaintance.
Morales asked Anna to reconstruct exactly how she navigated the flash drive. She described the directories she remembered opening. He took notes while Clare sketched the folder structure from memory. Names. Initials. Date ranges. Neutral abbreviations. One directory labeled with a single underscore had seemed empty when Anna first clicked it. She had ignored it.
Morales looked up. “An empty folder?”
“I thought it was.”
“Did you check hidden files?”
Anna shook her head.
Clare leaned back. “Could something have been there without showing normally?”
“Yes,” Morales said. “Easily.”
The copy Anna had made was no longer in her possession; Morales had secured one version, while another remained with Clare. He arranged for a digital forensics technician to examine the drive without altering metadata. Anna wanted immediate answers, but he resisted rushing. If they opened files carelessly, he explained, they could damage timestamps or later create arguments about evidence handling.
Waiting became its own form of pressure.
While the drive was examined, Anna underwent medical testing. Clare stayed nearby but did not enter the room unless asked. Blood was drawn. Urine samples were taken. Questions came carefully: when had the strange mornings begun, what did the tea taste like, how often did she wake confused, did she take any prescribed sleep medication, had she experienced blackouts before marrying Dererick? Anna answered each one and felt as if she were describing someone else’s life.
The clinician warned that many substances left the body quickly. A negative result would not prove nothing had happened. Anna understood, though part of her had wanted a test that could deliver certainty with a number.
Afterward, she sat in the corridor and stared at the adhesive bandage inside her elbow.
“I kept thanking him for making the tea,” she said.
Clare sat beside her.
Anna laughed once, without humor. “I used to tell people how lucky I was because my husband noticed when I was tired.”
Clare did not answer with reassurance. She only said, “You were reacting to the information you had.”
That was more bearable.
By late afternoon, Morales received the first report from digital forensics.
There was indeed hidden content.
The underscore directory contained an encrypted archive that had not appeared during Anna’s hurried inspection. It was copied onto the drive, but ordinary browsing would not reveal what was inside. Morales could not open it yet. The technician believed it required either a password, a key file, or both.
Anna immediately thought of the anonymous message.
“They knew.”
Morales nodded. “That is now a reasonable possibility.”
“Which means they know the encryption too.”
“Possibly.”
“What would Dererick hide there that he wouldn’t hide in the other files?”
Morales did not speculate.
Anna did.
Everything else she had seen was already terrible. If Dererick considered those records safe enough to leave on an ordinary flash drive, then whatever he had encrypted might represent something worse: identities, transactions, names of collaborators, or evidence linking his documentation to actual harm.
The thought of a collaborator kept returning.
Peterson’s footage showed a second person meeting Dererick near a vehicle. Someone had entered the house while Dererick was supposed to be at work. The unknown sender knew Anna had copied files. The recurring delivery vehicle connected to a company and postal box outside Dererick’s normal finances.
Pieces were forming a shape.
Morales asked whether Dererick used repeated phrases, anniversaries, pet names, or private references that could function as passwords. Anna felt an almost embarrassing intimacy in the question. She listed everything she could remember: their wedding date, the street where they first lived, the name of Dererick’s childhood dog, his mother’s birthday, several favorite quotations, the name of a small lake where he proposed.
The technician tried none of them immediately. Morales insisted on preserving process.
Clare, meanwhile, searched her own memory for things Dererick had said about computers. He disliked password managers. He preferred memorable systems. He once joked that the safest password was a sentence nobody else understood.
Anna remembered another detail.
“He used to say numbers mattered only when you knew what they measured.”
Morales wrote it down.
That evening, Peterson called.
He had seen Dererick.
Anna stood so quickly her chair scraped the floor.
“Where?”
“Your street.”
Peterson’s voice was low. “He drove past twice. Didn’t stop.”
“Did he see you?”
“I stayed inside.”
“Was he alone?”
“I couldn’t tell.”
Morales took over the call and instructed Peterson to remain away from windows, keep his doors locked, and contact police immediately if Dererick approached.
Anna felt useless in the guest room.
Her instinct was to go home, not because she missed the house but because Dererick was moving through a world that still believed he belonged there. He could drive down their street. He could look at their windows. He could test doors and ask neighbors questions. Anna was the one hiding.
The unfairness burned.
Clare recognized the expression. “Don’t confuse anger with safety.”
“I know.”
“You’re thinking about going back.”
“I’m thinking about him walking around like nothing happened.”
“That is not the same problem.”
Anna turned toward the window.
Below, evening traffic moved through the hospital entrance.
“He knows I’m gone.”
“Yes.”
“He probably knows I have the files.”
“Yes.”
“So pretending he doesn’t know isn’t protecting me anymore.”
Clare had no argument for that.
Morales did. “It still protects the investigation. You don’t know what he knows, and he doesn’t know what we know. That uncertainty matters.”
Anna forced herself to accept it.
The encrypted archive became their central problem.
Digital forensics found a clue in metadata. The archive had last been modified two nights before Anna refused the tea. That timing disturbed her. Dererick had updated the hidden material shortly before bringing the camera and vials into their bedroom.
“What happened that day?” Morales asked.
Anna tried to remember.
It had been a Tuesday. She worked from home. Dererick came back late. They ate leftover pasta. He seemed distracted. Nothing dramatic.
Then Anna remembered the package.
A small padded envelope had been delivered that afternoon. Dererick had taken it directly to his study and told her it contained replacement parts for a work device.
“Did you see the label?”
“Only briefly.”
“Courier?”
“I don’t remember.”
The recurring delivery vehicle came immediately to mind.
Morales requested footage from Peterson for that date.
Peterson found it within an hour.
At 3:42 p.m., a plain delivery van stopped outside Anna’s house. The driver carried a padded envelope to the door. Dererick was not home, so Anna accepted it herself.
Watching the footage made her skin prickle.
She remembered holding the package.
The driver’s face was barely visible, but Morales isolated several frames. The person wore a cap low over the forehead. Build average. Height difficult to estimate.
“Could that be the person you saw meeting Dererick?” Anna asked.
Peterson studied both recordings.
“Maybe.”
Not enough.
Morales requested registration information on the delivery company.
The company existed legally but had almost no public profile. It provided courier services to private clients. Its registered address belonged to a commercial office suite shared by dozens of small businesses.
Anna recognized the structure. Another layer.
Dererick did not simply hide information. He separated it.
Different names. Different addresses. Different channels.
The next clue arrived from Clare.
While reviewing the photographs Anna had taken inside the study, she noticed something on the edge of one image: a handwritten number partially visible beneath a stack of receipts. It contained eight digits separated into groups of two.
Anna enlarged the photograph.
“I never noticed that.”
Morales sent it to forensics.
The number did not unlock the archive.
But one technician recognized the pattern as possibly representing a date and time rather than a password.
Anna stared at it.
Four pairs.
Month. Day. Hour. Minute.
The first two digits formed a possible month. The next pair formed a possible date.
The final four matched 02:17.
Her chest tightened.
“That’s when he came into the bedroom.”
Clare looked at her.
The first four digits represented the same month and day as a date marked repeatedly beside Anna’s name in the notebook.
Not the night she stayed awake.
An earlier night.
Anna felt a pressure behind her eyes.
“What happened then?”
She searched her memory.
Nothing.
That was the problem.
She remembered going to dinner with Dererick. She remembered coming home. She remembered drinking tea.
Then morning.
A blank.
Morales stopped the discussion until Anna steadied herself.
The technician used the complete eight-digit sequence not as a password but as a key reference. Combined with another small file hidden elsewhere on the drive, it opened the archive.
No one spoke when Morales received the call.
He left the room to review the contents privately.
Anna watched the door.
Ten minutes passed.
Then twenty.
When Morales returned, his face had changed.
Not dramatically.
Enough.
“What is it?” Anna asked.
Morales sat down.
“The archive contains video.”
Anna’s hands went cold.
“Of me?”
“Some of it.”
Clare inhaled sharply.
Morales continued carefully. “There are recordings involving multiple people. We are still identifying dates and individuals. I do not want you viewing them right now.”
Anna almost argued.
Then she saw Clare’s face.
“What did he do?”
Morales chose every word.
“He documented people while they appeared impaired or unconscious. In several recordings, he performed procedures or took samples. Some files contain spoken commentary.”
Anna closed her eyes.
The syringe.
The vials.
The camera.
The notebook.
The hidden archive did not reveal a new behavior. It proved the behavior she had already witnessed belonged to a longer pattern.
“How many?”
“We don’t know yet.”
“Am I in more than one?”
“Yes.”
Anna opened her eyes.
“How many?”
Morales hesitated.
“Eleven identified so far.”
The room seemed to tilt.
Clare reached toward Anna but stopped before touching her.
Eleven.
Anna tried to locate eleven nights in memory and found only mornings: headaches, heavy limbs, Dererick saying she had slept deeply, tea cups in the sink.
She had believed memory was something that belonged to her.
Now Dererick possessed versions of nights she could not remember.
Morales said the investigation was escalating. Warrants were being prepared. The house, Dererick’s vehicles, known storage locations, and the courier connection would all be examined if approved.
Anna heard the words but barely processed them.
One question rose above the rest.
“Is anyone else in the videos with him?”
Morales looked at her.
“In at least two recordings, another person enters the frame.”
Anna stopped breathing.
“Can you identify them?”
“Not yet.”
“Man or woman?”
“Appears male.”
“The person from the car?”
“We don’t know.”
Anna thought of the anonymous message.
You missed one file.
Whoever sent it might have been warning her.
Or taunting her.
Or both.
Then Morales added one more fact.
The hidden archive contained a recently created folder.
Its title was not initials or numbers.
It was a full name.
Clare’s.
