"You've never been prescribed this?"
"No."
"Has anyone asked you to sign anything, or given you anything to take?"
I told her about the tea.
"All right," said Dr. Park. She took out her prescription pad and began writing quickly. "Because it's been more than three days since your last dose, a blood or urine test will most likely be clean. But a hair test can look back a month or more. I'm going to send a sample to a lab I trust. I'll document everything."
She clipped a small lock from the back of my head, tied it with a strip of foil, and sealed it in an envelope with her signature across the flap.
"Results in about ten days," she said. "And Nora, if this comes back the way I think it will, this isn't a family squabble. This is a crime."
That afternoon, I called the Fairlawn Family Pharmacy. I told the pharmacist I was checking on a prescription in my name.
"Yes, ma'am, we filled that October sixth," the pharmacist said. "It was picked up by Lorraine Bennett, your authorized representative."
"I never authorized anyone."
There was a long silence on the line.
"I'll note that in the file," the pharmacist said slowly. "You may want to speak with your attorney."
Ray came to my house the next day, dressed as a man from the cable company.
He carried a toolbox and a clipboard, and he spent twenty minutes in my kitchen "checking the wiring" while Lorraine sat in the living room with a crossword and Derek was out on a job.
When he left, there was a small white USB wall charger plugged into the outlet by the toaster, where I charged my phone every day.
It was a camera. Video only, no sound. It sent everything to a private cloud folder that Ray and Tamika and I could open.
"It'll catch whatever happens in that kitchen," Ray said quietly, on the front porch. "I need you to be somewhere else at eight thirty."
That night, I told Derek I was taking Eli over to Marisol's for a movie night, and I'd grab milk on the way home.
"Sure, babe," he said, distracted, looking at his phone. "Mom, do you need anything?"
"No, no. I'll just make Nora her tea before she goes," Lorraine said. "So it's ready when she gets back."
I sat in Marisol's driveway at 8:34 p.m., with Eli inside eating popcorn, and opened the video on my phone.
I watched my mother-in-law walk into my kitchen.
