Chapter 2 - THE CAR HE ABANDONED Phoenix police tracked Brandon’s sedan through freeway cameras while Lauren listened to the audio from the hidden monitoring application.

Most of what she heard was road noise.
Then Hannah cried.
The sound was weak, interrupted by short silences that frightened Lauren more than screaming would have.
“Why does she keep stopping?” Lauren asked.
The dispatcher did not answer.
An officer found the sedan behind a closed gas station twenty-seven minutes later. The driver’s door stood open. Brandon had disappeared into an alley between two storage buildings.
Hannah remained strapped inside her car seat.
She was alive.
Her body felt strangely limp when the paramedic lifted her. Her breathing was slow, and milk had dried beside her mouth.
Lauren climbed into the ambulance beside her.
“What happened?”
“We don’t know yet.”
At the emergency department, doctors discovered that Hannah’s heart rate had dropped dangerously low. Her blood pressure was unstable, and she responded sluggishly to light.
Dr. Lawson arrived before the toxicology results.
He examined the baby bottle recovered from the house and smelled the liquid.
“This isn’t formula alone.”
“What is it?”
“I need the laboratory to confirm it.”
Lauren looked through the hospital-room glass. Florence sat in another room with a bandage around her head, speaking to police.
“She knew.”
Dr. Lawson did not defend her.
“She may know part of it.”
Detective Mara Ortiz entered carrying Brandon’s phone, which officers had found beneath the passenger seat. Most messages had been erased, but one remained open.
Increase the evening amount. Fear response still inconsistent.
The sender was saved only as N.
Lauren read the message twice.
“Fear response?”
Ortiz placed a photograph beside it.
Police had found a small plastic case inside the trunk. It contained empty medicine droppers, adhesive skin sensors, and memory cards labeled with dates beginning six weeks earlier.
Every date matched a day Florence had watched Hannah.
Lauren entered Florence’s room.
Her mother-in-law looked older than she had that morning.
“What did you give my daughter?”
Florence began crying.
“Brandon said it was reflux medicine.”
“For six weeks?”
“He told me the pediatrician prescribed it.”
“Which pediatrician?”
“I never saw a name.”
“You never asked?”
“I did. He became angry.”
Lauren struck the table with both hands.
“And that was enough to make you stop asking?”
“No.”
Florence admitted that Hannah’s reaction changed after the third week. She began stiffening whenever Brandon entered the room. Sometimes the baby cried when she heard his car in the driveway.
Florence confronted him.
He said Hannah was entering a developmental phase and accused his mother of interfering with his parenting.
“Yesterday, I told him I would tell you,” Florence whispered. “He promised the medicine was gone.”
“Then why was it in today’s bottle?”
“I didn’t put it there.”
Lauren stared.
Florence claimed she had poured the bottle herself and left it on the kitchen counter for less than a minute while changing Hannah.
When she returned, Brandon had not yet entered through the front door.
But the back door had been unlocked.
Someone else could have reached the bottle.
The toxicology report arrived.
Hannah had been exposed to clonidine, a powerful medication that could reduce blood pressure and heart rate. But the laboratory also detected an unidentified synthetic compound.
Dr. Lawson stared at the chemical pattern.
“I’ve seen this before.”
“Where?”
His expression tightened.
“In a discontinued infant-monitoring trial.”
