Chapter 4 - The Bottle in the Cabinet.
The pediatric medicine cabinet was in the upstairs bathroom.
Lily had not touched it since Noah's fever broke two days earlier.
Officer Ruiz returned with a detective and sealed the bathroom before anyone could enter.
Detective Mara Voss was a quiet woman with gray eyes and a voice that never rose.
She asked Lily to describe every medicine Noah had taken during the last month.
Lily listed infant acetaminophen, saline drops, and a prescription antibiotic from an ear infection three weeks earlier.
Voss wrote everything down.
"Who administered the doses?"
"Mostly me."
Lily hesitated.
"Sometimes Eleanor."
Ethan's head snapped toward her.
"You let her give him medicine?"
The accusation hurt before he realized how it sounded.
Lily stood so quickly that the chair scraped the floor.
"I didn't let her do anything."
Ethan's face fell.
"Lily, I didn't mean—"
"She took the bottle out of my hand because she said I was measuring it wrong."
Voss raised one hand.
"This is exactly how control works."
The room quieted.
"The important question is what happened, not who failed to stop it."
An evidence technician came downstairs carrying a sealed plastic bag.
Inside was the medicine bottle.
A cloudy residue had settled at the bottom.
Voss looked at Lily.
"Did it look like that before?"
"No."
The answer came immediately.
Ethan sat with his elbows on his knees.
"What could be in it?"
"We won't guess."
Voss's tone was firm.
"We'll test it."
Noah woke and began to fuss.
Lily reached for him, but her hands were shaking too badly.
Ethan lifted the baby and paced slowly across the living room.
Noah settled against his shoulder.
For the first time, Lily watched Ethan really look at their son.
Not as a problem to solve.
Not as a responsibility between meetings.
As a child who might have been harmed inside his own home.
Detective Voss asked another question.
"Did Eleanor ever insist that Noah seemed sicker when Ethan was away?"
Lily went still.
Every Monday and Thursday, Ethan worked late.
Those were always the nights Noah somehow developed a fever, vomited, or became unusually sleepy.
Eleanor would take charge.
She would tell Ethan over the phone that Lily was panicking.
She would tell him Lily had forgotten a dose or misread the thermometer.
By the time Ethan arrived home, Noah was usually improving.
And Eleanor looked like the hero.
"Oh my God."
Lily covered her mouth.
Voss's eyes hardened.
"What?"
Lily told her.
The detective wrote faster.
Ethan stopped pacing.
"She made him sick to make Lily look incompetent?"
"We do not know that yet."
But Voss no longer sounded neutral.
An hour later, Noah was taken to the hospital for bloodwork.
The tests showed no immediate danger.
Lily cried with relief until the pediatric toxicologist entered the room.
He carried a printed lab sheet from the medicine bottle.
"We found an antihistamine in concentrations far above what should be present."
Ethan gripped the bed rail.
"Could it make a child sleepy?"
"Very."
The doctor pointed lower on the page.
"But that isn't the only thing we found."
Lily looked at him.
"What else?"
The doctor took a breath.
"A medication commonly prescribed to adults for blood pressure."

Ethan stared at the paper.
Eleanor took that exact medication every morning.
