Chapter 5 - The Blue Key
Rachel sat down because her legs suddenly refused to cooperate.
“What exactly did she say?”
Caleb stood near the hallway wall, the blanket still around his shoulders.
“She asked Mia if she knew where Daddy put the blue key.”
Rachel stared at him.
“Those words?”
“Yes.”
“Why didn’t you tell me before?”
Caleb’s face tightened.
“I forgot.”
Rachel almost snapped.
Then stopped herself.
He was nine.
He had spent the last hour protecting his four-year-old sister from a stranger.
Of course he forgot things.
“Okay,” Rachel said softly. “That’s okay.”
Officer Mercer watched her.
“What blue key?”
Rachel looked toward the kitchen.
“My ex-husband had a small lockbox.”
Mercer waited.
“For documents,” Rachel continued. “Passports, birth certificates. Insurance. Things like that.”
“Where is it?”
“In the basement.”
“Does the key open it?”
“Yes.”
“Where is the key?”
Rachel hesitated.
“I don’t know.”
Mercer frowned.
“You just said—”
“I know where it used to be.”
She looked at Caleb.
“Your father kept it in his desk.”
Caleb shook his head.
“Not anymore.”
Rachel looked at him.
“What?”
Caleb shrugged.
“He gave it to Mia.”
“When?”
“A long time ago.”
Rachel’s stomach turned.
“Why?”
“She liked the color.”
That sounded exactly like Mark.
Rachel’s ex-husband had possessed a remarkable ability to treat important objects like toys and toys like important objects.
“You saw him give it to her?”
“Yes.”
“Where did she put it?”
Caleb looked toward his sleeping sister.
“In her treasure box.”
Rachel stood.
Mia’s treasure box was a purple plastic case shaped like a castle.
It contained stickers, beads, two broken crayons, coins, hair clips, and whatever else she decided was valuable that week.
Rachel walked quickly toward Mia’s bedroom.
Mercer followed.
The castle box sat on the shelf beside her bed.
Rachel opened it.
Plastic jewelry.
A small shell.
Three buttons.
A toy ring.
No key.
She searched again.
Nothing.
Mercer said, “Could she have moved it?”
“She moves everything.”
Rachel’s frustration rose.
Then another thought hit her.
“Why would the stranger know about it?”
Mercer did not answer.
Rachel turned.
“She had Julia’s phone. Julia wouldn’t know about that key.”
“Maybe there was a message.”
“No.”
“You sure?”
“Yes.”
Rachel thought harder.
Then remembered.
A photograph.
Months earlier, Mark had texted Rachel asking if she still had the lockbox because he needed a copy of an old insurance document.
Rachel had replied with a photo of the box.
Mia had been sitting beside it.
Holding something blue.
Rachel closed her eyes.
The family message thread.
Not Julia.
Her own phone.
But Julia would not have those messages.
Unless—
Rachel looked at Mercer.
“Was there more than one stolen phone?”
“Three.”
“One was Julia’s.”
“Yes.”
“Whose were the others?”
“We’re checking.”
Rachel’s mind raced.
Could one belong to Mark?
No.
He lived in Portland now.
Could it be random?
Could the stranger have been collecting phones?
Mercer’s radio crackled again.
He answered quietly.
Then looked at Rachel.
“What?”
He ended the call.
“The suspect has given us a name.”
Rachel felt her shoulders tense.
“Whose name?”
“Your former husband.”
For a moment, Rachel thought she had misheard him.
“Mark?”
Mercer nodded.
“She claims she knows him.”
“That’s impossible.”
“Why?”
“Because he would have told me.”
Mercer’s expression stayed neutral.
Rachel hated that expression.
It was the face people used when they knew not to trust anyone’s certainty.
“She says your ex-husband owes her money.”
Rachel laughed once.
Sharp.
Disbelieving.
“Mark owes half of Seattle money.”
“She says he left something valuable in the lockbox.”
Rachel stopped.
“What?”
Mercer continued.
“She believed the key was still in the house.”
Rachel shook her head.
“No. That makes no sense.”
“Maybe not.”
“What did she want?”
“She says documents.”
“What documents?”
“She hasn’t specified.”
Rachel turned toward Mia’s treasure box.
Something was wrong.
Not just with the story.
With the woman’s entire approach.
If she wanted documents from a basement lockbox, why pretend to be a babysitter?
Why involve Mia?
Then she understood.
Because Mia knew the key.
Or the stranger believed she did.
She had seen the child with it.
Perhaps in a photo.
Maybe she had enough messages from some device to piece together the family.
But whose device?
Rachel turned.
“Where is Julia’s stolen phone now?”
“With evidence.”
“Was it unlocked?”
“Apparently.”
“Did the suspect know the passcode?”
“We’re investigating.”
Rachel thought of Julia’s habits.
The woman had used facial recognition.
Rachel had seen her unlock the phone during their meeting.
If the thief had taken it while it was open…
Rachel’s stomach tightened.
A single unlocked device could contain weeks of messages.
Names.
Addresses.
Photographs.
Schedules.
Security instructions.
But still not Mark’s private information.
Unless Julia and Mark somehow—
No.
That made no sense.
Caleb stood in the doorway.
“Mom?”
Rachel looked at him.
“What?”
“She lied again.”
“Who?”
“The fake Julia.”
Mercer turned.
“What did she lie about?”
Caleb rubbed one foot against the carpet.
“She said Dad told her about the key.”
Rachel’s heart skipped.
“When?”
“Before I locked the door.”
“Why didn’t you say that?”
“You kept asking about Julia.”
Rachel shut her mouth.
Fair.
Very fair.
“What exactly did she say?”
Caleb frowned, trying to remember.
“She said, ‘Your dad said Mia would know where it is.’”
Rachel’s skin went cold.
Mercer asked, “Did your father ever meet this woman?”
Caleb shook his head.
“I don’t think so.”
Rachel looked at her son.
“How do you know?”
Caleb hesitated.
Then said the sentence that changed the entire case.
“Because Dad doesn’t call Mia Mia when he talks about her.”
Rachel stared at him.
“What?”
“He calls her Amelia.”
Rachel’s ex-husband was the only person in the family who refused to use Mia’s nickname.
Always Amelia.
From the day she was born.
Rachel turned slowly toward Mercer.
The stranger had not spoken to Mark.
She was pretending she had.
Just as she had pretended to know Julia.
She had learned facts.
May you like
But she did not know the people.
And Caleb kept catching the difference.
