Chapter 3 - Someone Had Been Dosing My Wife

The doctor was careful.
He didn't call it poisoning.
He didn't accuse Serena.
He explained that Madeline’s blood contained a sedating prescription medication that wasn't listed in her medical chart.
Enough could cause dizziness, confusion, extreme drowsiness, and in combination with other factors, loss of consciousness.
“How long?”
“We can't determine that from one sample.”
“Could it have been given today?”
“Yes.”
“Could it have been given repeatedly?”
“Yes.”
My stomach tightened.
For three weeks, Madeline had been acting different.
Tired.
Forgetful.
She once left the stove on.
Another time she couldn't remember whether she'd given Poppy lunch.
I suggested she see a doctor.
Madeline became defensive.
“I’m exhausted, Preston. Not insane.”
I apologized.
Then quietly started wondering whether motherhood, work, or grief over her father had become too much.
Now I hated myself for doubting her.
“What medication?”
The doctor told me.
Then Serena whispered:
“Claire takes that.”
I turned.
The vial from Serena’s purse contained the same medication.
That looked devastating.
Serena immediately shook her head.
“No. No, Preston, listen.”
“Why should I?”
“Because Claire’s prescription is tablets.”
I froze.
“What?”
“The vial isn't hers.”
“But her name is on it.”
“Claire doesn't use injections.”
The doctor couldn't verify that without records.
Serena became frantic.
“Someone copied her label.”
I almost laughed.
“You expect me to believe somebody manufactured evidence against you?”
Her face hardened.
“Yes.”
Then she said:
“Because that's exactly what Madeline suspected was happening to her.”
I stopped.
“What did you say?”
Serena reached slowly toward her handbag.
Security stopped her.
“My wallet. There's a note.”
An officer retrieved it.
Inside was a folded card.
Madeline’s handwriting.
I knew it instantly.
**If anything happens to me before Friday, do not trust the first evidence you find.**
My heart started pounding.
Below that:
**Ask Preston about the blue tea tin.**
I looked at Serena.
“What blue tea tin?”
“I don't know.”
I did.
At home, Madeline kept a decorative blue tin above the kitchen cabinets.
She hated tea.
I had always assumed it was decorative.
The hospital allowed me to leave Poppy with my sister Rebecca while I went home with appropriate assistance.
I found the tin exactly where it had been for years.
Inside were no tea bags.
There were tiny sealed plastic sleeves.
One for each date.
Inside each sleeve:
A few crumbs.
Powder.
Fragments from food or drink.
Madeline had been collecting samples.
There was also a handwritten log.
**June 3 — dizzy after coffee.**
**June 7 — slept four hours after breakfast.**
**June 11 — confusion after soup.**
**June 14 — Poppy refused my juice and screamed.**
That line made me stop breathing.
Poppy had noticed something.
Maybe smell.
Taste.
Maybe nothing specific.
But Madeline noticed her reaction.
Then came the final entry.
**June 18 — Serena coming tomorrow. If she's involved, I'll know. If she isn't, someone wants me to think she is.**
Someone wanted Madeline to suspect Serena.
I returned to the hospital with the tin.
Serena looked at it and whispered:
“She figured it out.”
“Figured what out?”
Serena's eyes filled.
“That Claire isn't the secret.”
“Then what is?”
Before she could answer, my sister called.
“Preston, there's something in Poppy’s diaper bag.”
“What?”
“A key taped under the lining.”
I went cold.
“Whose key?”
Rebecca read the engraving.
It belonged to a private storage facility.

And underneath it, Madeline had written one word.
**PRESTON.**
