My Mother-in-law Smiled While My Daughter Choked At Sunday Dinner. She Thinks It Was An Accident, But I’m An Er Nurse And I Know She’s Poisoning Her. How Do I Catch Her Before It’s Too Late?

“She’s beside herself with worry.”

“Is she?”

I said flatly.

“Of course, she’d never intentionally—”

I didn’t say she did, but I was thinking it. I’d been thinking it since the moment Katie’s throat started closing because I’d seen Patricia’s face.

I’d seen that calculating look before the concern slid into place like a mask. Katie spent the night in the hospital, and I stayed with her, dozing in the chair beside her bed, waking every time a monitor beeped.

Around 3:00 in the morning, when the hospital was at its quietest, Katie whispered,

“Mom?”

“I’m here, honey.”

“The chicken tasted funny. Just for a second. Like oily.”

“Oily? How?”

“I don’t know. Different. But I thought maybe mother was trying a new recipe.”

I sat up straighter.

“Katie, when you say oily—”

“Just… I don’t know, Mom. Maybe I imagined it.”

She closed her eyes again. The Benadryl was making her drowsy, but I couldn’t sleep anymore.

Oily. Peanut oil had a distinct taste if you knew what you were looking for.

And Patricia Morrison was an excellent cook. She would know exactly how to disguise it.

The next morning, Katie was discharged with a new EpiPen prescription and instructions to follow up with her allergist. Brian picked us up, fussing over Katie and shooting me nervous glances in the rearview mirror.

“Mother wants you both to come over,”

he said.

“She wants to apologize in person.”

“For what?”

I asked sharply.

“Accidentally almost killing your wife?”

“Mom,”

Katie said softly.

She always hated confrontation—my gentle girl who’d rather swallow broken glass than make a scene.

“We don’t know it was the food,”

Brian said.

“Could have been anything. Dust, pollen in March in your mother’s spotless house.”

I couldn’t keep the edge out of my voice.

“Brian, Katie ate one bite of that chicken and went into anaphylactic shock.”

“One bite. We can’t prove—”

“I want the leftovers tested.”

The car went silent. Katie looked at me with wide eyes.

Brian’s hands tightened on the steering wheel.

“That’s… that’s ridiculous, Margaret,”

Brian said finally.

“Mother would never.”

“Then the test will show nothing and we can all rest easy.”

But Brian didn’t offer to get the leftovers tested. And when we got back to Katie and Brian’s condo in White Plains, Patricia was there, sitting in their living room with her own key like she owned the place.

“Katie, darling!”

Patricia stood, arms outstretched.

“How terrifying that must have been.”

Katie hugged her mother-in-law dutifully. I stayed in the doorway, watching Patricia’s face over Katie’s shoulder.

Patricia’s eyes met mine for just a second. In that second, I saw the truth, and she knew I’d seen it.

“I’ve brought you homemade soup,”

Patricia said, releasing Katie and gesturing to a covered pot on the kitchen counter.

“Chicken noodle. Nothing exotic. Nothing that could possibly cause a reaction.”

“That’s very kind,”

Katie said, ever the peacemaker.

“I’ll just put it in the fridge for you.”

Patricia moved toward the kitchen. I followed.

“You tried to kill her,”

I said quietly once we were out of earshot.

Patricia’s hand paused on the refrigerator handle. Then she laughed—a light, tinkling sound.

“Margaret, you’re being hysterical. The stress of last night—”

“You used peanut oil in that chicken. Katie tasted it.”

“Katie was confused. Anaphylaxis causes disorientation. I’m a nurse. Don’t play doctor with me.”

Patricia turned to face me fully. Her smile was gone now, replaced with something cold and sharp.

“You’re a retired nurse with a persecution complex. My son married your daughter out of love, but you’ve never accepted me as family. Now you’re creating drama where there is none.”

“Katie could have died.”

“But she didn’t, thanks to your quick action with the EpiPen.”

Patricia’s voice was syrupy now.

*”You were wonderful, Margaret. A true hero. Brian told me how you just took charge.”

She was good; I’d give her that. Every word calculated, turning the narrative, making me the crazy mother-in-law seeing conspiracies.

“Stay away from my daughter,”

I said.

“I’m afraid that’s not your decision to make. Katie is my family now. She’s a Morrison.”

Patricia smiled again, opening the refrigerator.

“Do you take anything in your coffee, Margaret? You look exhausted. Why don’t you let me—”
