My name is Elena Moreau , and I am fifty-nine years old. Six years ago, I married Daniel Keller , a young German architect thirty years my junior. Everyone said that love knows no age, and for a while, I wanted to believe it. Daniel called me “my little wife ,” and although the expression sounded childish to me, his soft voice made it feel like a caress. We lived in a modern house on the outskirts of Marseille, where the air smelled of pine and salt.

From the beginning, Daniel insisted on a peculiar habit: every night, before going to sleep, I had to drink a glass of water that he prepared himself. He said it was for my health, to keep me hydrated. At first, I thought it was a sweet gesture, until I started noticing strange things.

Some mornings I would wake up with a metallic taste in my mouth and a kind of mental fog that prevented me from remembering the details of the previous day. Daniel attributed it to my age. “The body changes, my little wife,” he would say, smiling, as he stroked my hair. But one day, checking the calendar, I discovered that almost a week had passed without me leaving the house. I didn’t remember cooking or speaking to anyone. I only had vague images: the light in the hallway, Daniel’s voice telling me to rest.

That night, I pretended to drink the water. When he fell asleep, I went down to the kitchen. The clock read two in the morning. Everything was tidy, as usual. I opened the refrigerator: bottles of white wine, vegetables, and a clear pitcher of water. I noticed a faint, almost imperceptible white sediment at the bottom. My hands were trembling. I looked for my phone, but it wasn’t where I’d left it. Then I heard a noise: a drawer closing in Daniel’s office.

I crept closer and, through the crack in the door, I saw him. Daniel was going through a folder with my name on it: “ Elena – follow-up .” Inside were sheets with medical notes, medication schedules, and photographs of me asleep. In the top corner, a word was underlined in red: “Cognitive control – final stage . ”
I felt the air leave my chest. My husband, my young and attentive Daniel, was dosing me something every night.

And that jug of water was just the beginning.

I didn’t sleep that night. When Daniel woke up, I pretended everything was normal. I poured him coffee, smiled, and even thanked him for his concern for my health. Inside, a whirlwind was raging. I needed to understand what he was doing to me.

During the day, while he worked in his studio, I searched the house. On the desk, I found a small key inside an envelope. It opened a basement door, a place he never went into because he said he kept “dangerous tools” there. I went downstairs, my heart in my throat.

The air was thick, laced with the smell of metal. On a table lay test tubes, boxes of medicine, and bottles labeled in German: Memorin, Clorazet, Neurofix . In a corner, a computer displayed graphs with my name and a line that descended week after week: “retention capacity – 38%.”

I opened a file. It was an email addressed to someone named Dr. Heinrich Bauer . Daniel wrote:

“The subject shows mild memory loss but still maintains autonomy. Nighttime dose adjusted. Promising results.”

The subject. That’s what he called me. I was his experiment.

Everything clicked at once: the forgetfulness, the drowsiness, the days erased from my mind. I remembered that Daniel had worked in a pharmaceutical lab before becoming an architect. He had vaguely mentioned a project on neuroplasticity and behavioral control.

When I heard his car return, I locked everything up and went back upstairs. That night, when he offered me the glass of water, I smiled and took only a sip. I put the rest in a bottle that I hid under the bed.

For the next few days, I feigned obedience while I had the substance tested at a nearby pharmacy. The chemist who helped me was surprised:
“Where did you get this?” he asked.
“My husband gives it to me every night,” I replied.
He lowered his voice.
“This isn’t water. It’s an experimental tranquilizer. Some labs use it to induce states of submission. It’s banned in human trials.”

I left there trembling. Daniel, the man who called me “little wife ,” was slowly erasing me from his life.

I had to act before my mind completely fell apart. But how could I confront him without him suspecting anything?

The following night, when he offered me the glass, I asked him to drink with me. He smiled, but his expression changed for barely an instant. I understood then that he knew that I knew. And at that moment, the real danger began.

The following days were a silent charade. We feigned affection, but every gesture was a trap. I continued to save the doses he offered me; he, increasingly restless, began to observe me with scientific detachment.

I decided to contact Sophie , my niece, a journalist in Paris. I told her everything in a coded message. I asked her not to reply, just to come. She arrived two days later, pretending to be a family visitor.

While Daniel left for work, we went down to the basement and filmed everything: the jars, the emails, the samples. Sophie was crying as she filmed. “This is a crime, Auntie,” she kept saying. I could barely stand. Fear had aged me ten years.

That night, when Daniel returned, the tension was unbearable. He poured me water as usual, but this time he placed it directly into my hands.
“Drink, my little wife. You need it.
” “Why don’t we drink together?” I replied.

Her smile crumbled. The silence that followed was long and icy. Then, in a calm voice, she said,
“You don’t understand, Elena. It’s not poison. It’s protection. You volunteered.”

His words hit me hard. “Volunteer?” I searched through my memories and something surfaced: a signature on a document, six years ago, when we first started dating. He had asked me to participate in a study “to improve memory in older women.” I, in love, trusted him.

Daniel continued:
“You agreed. You said you wanted to stay young, lucid. We did it together. But when the effects kicked in, you became unpredictable. I had to keep an eye on you.”

I stared at him, incredulous. There was no madness in his tone; he spoke like a researcher justifying his experiment. At that moment, Sophie appeared from the hallway, her camera rolling.
“Everything’s on record,” she said firmly. “That’s enough, Daniel.”

He tried to snatch the camera from her, but tripped over the table. The glass shattered into a thousand pieces. Amidst the shards, water formed a small puddle.
When the police arrived—alerted by Sophie before entering—Daniel offered no resistance. He simply repeated one phrase:
“I loved her. I wanted to protect her from herself.”

Months later, I testified at the trial. Doctors confirmed that I had been ingesting microdoses of an experimental sedative for years. My body recovered, but my mind has gaps I will never fill.

Sometimes, when I drink a glass of water before bed, I still hear his voice: “My little wife, this is for your own good.”
And then I remember that love, when disguised as care, can be the most subtle poison of all.
