lied and said they were happy for me.

He was thirty-one years younger.

I was a retired literature teacher with a townhouse, investments, and a villa in Malibu my late husband and I had once called our old-age dream.

Ethan was handsome, flexible, attentive, and strangely unbothered by criticism.

He told me people feared unusual love stories because they were too timid to live one.

I mistook that line for courage.

When I opened the front door that afternoon, Ethan called from the kitchen as if nothing in the world had shifted.

There you are, little wife.

I was just making lentil soup.

His voice floated toward me warm as steam.

I stood in the entryway with my purse still on my shoulder and looked at the life I had been living: his running shoes by the stairs, his ceramic tea cups on the rack, the cardigan I had bought him folded over the chair.

Every object seemed to belong to a play that had ended while the actors were still smiling.

I answered him in the same tone I always used.

That became my first act of survival.

The performance started that night.

He brought me my usual warm water with honey and chamomile at ten-fifteen.

I took it from him, kissed his cheek, waited until he went downstairs for his phone, and emptied the glass into a mason jar I had hidden beneath the bathroom sink.

Then I rinsed the glass, filled it with tap water, and placed it back on the nightstand half-empty so it would seem I had drunk most of it.

When he came back up, he smiled at the sight of the glass.

The next morning I called my niece Ava.

Of everyone in my family, she was the one I trusted most to do the practical thing first and the emotional thing second.

She was thirty-four, sharp as winter glass, and worked in estate litigation.

We had not been as close during my marriage as we once were.

She never hid her distrust of Ethan, and I never forgave how bluntly she had delivered it.

But when she answered and heard my voice, she did not waste a second on I told you so.

I need you to come over, I said.

She arrived in forty minutes with her hair twisted into a loose knot and three legal pads in her bag.

I told her everything from the amber vial to the doctor.

As I spoke, the color drained from her face, then returned in a colder form.

Do you have the bottle from the clinic? she asked.

No, they kept it for testing.

Have you saved any more?

I showed her the mason jar under the sink.

Good, she said.

Save every single dose from now on.

Date them.

Photograph them.

Do not confront him.

Do not sign anything.

And Aunt Lillian…

from this moment on, assume he is not improvising.

Assume he has a plan.

Those last words landed hardest because I already knew she was right.

Two days later the hair test came back.

Repeated exposure.

Not for a week or two.

For months.

Possibly longer.

The doctor explained that because
