The twins were slowly fading away, but their father didn’t understand why. Before leaving, he installed cameras to make sure nothing was threatening the children. But when he saw the footage, he took the first flight back immediately…

And call an ambulance. In the children’s room, Thomas and Carl were sitting on the bed for the first time in a long while, enthusiastically playing a board game. Rebecca watched them with tears in her eyes.

The experiment was over. Now she had all the evidence she needed. Marcus arrived an hour after Rebecca’s call, holding an envelope with the test results.

His face was grim. You were right. The powder contains heavy metal salts.

This is slow poisoning. Rebecca took out her notes. Look, I documented everything.

Tiffany was preparing the food for the children, and their condition started to improve. Here are the blood test results. And here, photos of the medications I found.

She wasn’t giving them the prescribed medicine. Instead, she was. Marcus sank heavily into the chair.

How long has this been going on? According to the medical records, about three months. I found receipts from a chemical laboratory where she ordered these drugs. Rebecca also played the voice recording.

Tiffany’s voice, mumbling about conversations with her late sister, filled the room. We need to call the police immediately. Marcus reached for the phone.

Wait, Rebecca stopped him. First, we need to secure the children. I asked Alice to take them to the back room and lock the door.

Now listen to my plan. They didn’t notice Tiffany standing in the doorway. Her eyes were strangely empty.

What are you doing in my room? She asked in a lifeless voice. Tiffany, sit down, Rebecca calmly suggested. We need to talk.

About what? About how you’re interfering with me helping the children? Fiona is asking to take them with her. They need to be with their mom. Fiona died three years ago, Marcus said softly.

She can’t come to you. No. She comes.

Every night. She asks me to save the children from this life without her. I found a way.

Slowly. Painlessly. Rebecca placed the test results on the table.

You poisoned them. Gradually. Day by day.

Here’s the evidence. Tiffany grabbed the papers and started tearing them apart. It’s not true.

I was helping them. They would just fall asleep and wake up with mom. Call an ambulance, Rebecca whispered to Marcus.

And the police. Just quietly. Where are the children? Suddenly, Tiffany asked.

What did you do to them? They’re safe, Rebecca replied. And you won’t be able to poison them anymore. Tiffany rushed toward the door, but Marcus managed to intercept her.

Let me go. I have to finish. Fiona is waiting for them.

A few minutes later, the sound of sirens was heard. Tiffany slumped in Marcus’ arms. Tears were streaming down her cheeks.

I just wanted them to be with their mom. That’s all. The house became unusually crowded, paramedics, investigators.

Marcus was examining the boys in the presence of the medical commission. Surprisingly, but serious consequences were avoided, he said, checking the children’s reactions. Thanks to Rebecca’s timely intervention.

In the next room, Tiffany sat in a chair, her hands limp. The investigator was patiently taking notes of her disjointed account. It started after Fiona’s anniversary, she said quietly…
