Chapter 7 - The Children Before HannahThe investigation into Nathan Mercer expanded beyond anything Briarwood Police could manage alone.
State investigators joined.
Federal agencies coordinated medical records from three states.
Hospitals opened archives that had not been touched in years.
Nathan’s career became a timeline.
At every institution where he trained or worked, investigators looked for unexplained pediatric illnesses clustered around his access.
Most meant nothing.
Children become sick.
Treatments fail.
Rare conditions exist.
Nobody wanted to turn tragedy into accusation merely because Nathan happened to have been present.
But patterns began emerging.
One patient stood out.
Eli Patterson.
Six years old when Nathan was a resident.
Eli had entered the hospital for a minor infection and subsequently developed a series of bizarre symptoms.
His mother, Denise, complained that Eli seemed worse after certain overnight shifts.
She was dismissed as exhausted and anxious.
Then Eli was transferred to another hospital.
His mysterious symptoms stopped.
Completely.
Denise had filed a complaint.
The hospital investigated.
Nathan denied wrongdoing.
No evidence was found.
Case closed.
Mara flew to meet Denise.
The woman was now fifty-one, living outside Columbus.
Eli was twenty.
Healthy.
Denise invited Mara into a modest kitchen and placed a cardboard box on the table.
“I kept everything.”
Mara almost smiled.
Mothers and receipts.
Nathan should have learned.
Inside were medical records, handwritten logs, discharge papers, and something unexpected.
A cassette recorder.
“My mother told me to record conversations because nobody believed me.”
The old tapes had been transferred digitally years later.
On one recording, a young Nathan spoke to Denise.
His voice was unmistakable.
Calm.
Reassuring.
Condescending.
“You’re interpreting normal fluctuations as evidence because you’re frightened.”
Denise’s younger voice answered.
“He gets worse after you’re here.”
“That kind of thinking can become dangerous, Mrs. Patterson.”
“You think I’m imagining it?”
“I think stress changes perception.”
Mara felt a chill.
The same language he later used on Emily.
Denise paused the recording.
“You know what bothered me most?”
“What?”
“He wasn’t angry that I accused him.”
She looked at Mara.
“He seemed interested.”
“Interested?”
“Like he wanted to know how much I had noticed.”
Mara wrote the statement down.
“Did you ever see him give Eli anything?”
“No.”
“Any witness?”
“My mother saw him enter Eli’s room once when he wasn’t scheduled.”
“Is she alive?”
“No.”
“I’m sorry.”
Denise looked at the box.
“I spent years wondering if I was crazy.”
“You weren’t.”
Her eyes filled.
“That would have mattered twenty years ago.”
Mara had no answer.
Back in Briarwood, Nathan’s public image collapsed.
The hospital removed his photograph.
Charities distanced themselves.
News stations replayed old interviews in which he spoke about protecting children.
Families demanded answers.
Yet investigators still could not locate him.
Nathan had money, medical knowledge, and years of planning.
But his greatest advantage remained psychological.
He understood institutions.
He knew what documents mattered.
Which databases were monitored.
How people behaved under stress.
Then Lucy provided the clue adults missed.
She was drawing during a therapy session when she sketched a small blue house.
Emily saw it.
“What’s that?”
“Daddy’s quiet house.”
Emily frowned.
“What quiet house?”
“The one where he took us when you visited Aunt Sarah.”
Emily’s heart raced.
“When?”
“Before Aunt Sarah went to heaven.”
“Where was it?”
Lucy shrugged.
“Near cows.”
The therapist immediately notified investigators.
Mara interviewed Lucy carefully.
No leading questions.
The child remembered fragments.
A long drive.
A red barn.
A blue house.
A windmill.
Nathan told the girls they were playing “hospital.”
Hannah had lain on a couch.
Lucy watched television.
“Did Hannah get sick there?”
Lucy nodded.
“When?”
“After Daddy practiced.”
“Practiced what?”
“Being her doctor.”
Mara asked Emily about the trip.
Emily remembered leaving Nathan with the girls for an afternoon while she spent time with Sarah.
Nathan claimed he had taken them to a park.
Property searches found no blue house under Nathan’s name.
Then investigators examined companies associated with his medical consulting income.
One shell corporation had paid property taxes on a rural parcel seventy miles west.
Farm country.
A red barn stood beside it.
And a faded blue cottage.
Police obtained a warrant.
The house looked abandoned.
Inside, however, was one locked room.
Shelves held old files, medical textbooks, and sealed storage bins.
Investigators documented everything.
No dangerous materials were discussed publicly.
What mattered were the records.
Nathan had kept journals.
Not emotional diaries.
Clinical observations.
Human beings reduced to initials, dates, symptoms, reactions.
E.P.
Investigators believed that meant Eli Patterson.
S.L.
Sarah Lawson.
H.M.
Hannah Mercer.
There were others.
Many remained unidentified.
Mara stood in the center of the room reading one entry after another.
Nathan had not viewed himself as a criminal.
He viewed himself as an observer.
He wrote about trust.
Authority.
How easily parents accepted conclusions from a confident physician.
One line made Mara stop.
The diagnosis often matters less than who is permitted to define reality.
Terrence read over her shoulder.
“He thinks everyone is an experiment.”
“No.”
Mara closed the journal.
“He thinks everyone is an audience.”
On another shelf, officers discovered photographs.
Not victims.
Places.
Police stations.
Hospitals.
Schools.
Including Briarwood Police Department.
A photograph showed the front entrance.
Taken months earlier.
Terrence stared.
“He knew where the girls would go.”
Mara shook her head.
“He knew where Emily had told them to go.”
“Same difference.”
“Maybe not.”
Nathan had studied his family’s escape routes.
Meaning he had anticipated rebellion.
But why allow Lucy access to the syringe?
Why leave Emily’s phone?
Why leave clues?
Terrence asked the question.
Mara answered slowly.
“Because he never believed they could actually beat him.”
Hubris.
Nathan’s planning was meticulous.
His understanding of other people was not.
Lucy had not behaved like a frightened child in his mental model.
Emily had not remained isolated.
Sarah had investigated.
Denise Patterson had kept records.
Every woman Nathan underestimated had left something behind.
Near sunset, forensic technicians found a recent item in the cottage.
A grocery receipt.
Three days old.
Nathan had been there after disappearing.
Security footage from the rural store confirmed it.
He wore a baseball cap and glasses.
He purchased food with cash.
A clerk remembered him because he asked about road closures near the county line.
“He was planning travel,” Mara said.
Terrence looked at the map.
“Or checking which roads police were blocking.”
Then an analyst interrupted.
“We found another entry.”
It was dated two months before Lucy and Hannah went to the station.
Nathan wrote:
E suspects more than she says. Sarah’s files remain unresolved. L increasingly observant. H remains suggestible. Contingency may become necessary.
Emily read it.
“L is Lucy.”
“Yes.”
“He knew.”
Mara nodded.
Emily sat down.
“He knew she was watching him.”
Another page contained only one sentence.
If exposure occurs, the family must become unreliable before I do.
Nathan’s plan had been bigger than disappearing.
He intended to discredit them.
Perhaps frame Emily.
Perhaps manipulate evidence.
Perhaps create enough confusion that every accusation became debatable.
Then an officer found a laptop hidden beneath a loose floorboard.
Its drive contained scheduled emails.
Most had never sent.
One was set for the following morning at 8:00.
Recipient list:
News outlets.
Hospital board.
State medical licensing authority.
Police oversight office.
Subject:
CONFESSION OF EMILY MERCER
Mara opened the draft.
It was written as though Emily had composed it.
She supposedly admitted fabricating allegations against Nathan, poisoning Hannah herself, and falsely blaming her husband during a mental breakdown.
Attached were altered documents and edited recordings.
Emily stared at the screen.
“He was going to blame me.”
Mara nodded.
“And tomorrow morning hundreds of people would receive it.”
“Can you stop it?”
“We already did.”
Emily covered her face.
Nathan had almost rewritten reality again.
Then an analyst spoke from the laptop station.
“Detective?”
Mara looked over.
“There’s remote-login activity.”
“Now?”
“Someone tried accessing this computer fifteen minutes ago.”
“Location?”
“We’re tracing it.”
A minute passed.
Then another.
Finally:
“Briarwood.”
Mara froze.
“He came back?”
“Looks like it.”
“Where?”
The analyst read the address.
Emily stood so quickly her chair fell.
“No.”
Mara turned.
“You recognize it?”
Emily’s face went white.
“Yes.”
The address belonged to Sarah Lawson’s former home.
It had remained empty while probate was completed.

Nathan had returned to the beginning.
