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…

The day of departure was gloomy and unsettling. Leon walked around the house, repeatedly checking his phone with the surveillance system. Rebecca, I’ve written down all the phone numbers, mine, Marcus’s, emergency services.

Call at any time, even at night. Don’t worry, Leon. I’ll keep an eye on everything, Rebecca replied calmly, making notes in her notebook.

Dad, will you come back soon? Thomas asked in a weak voice when his father came to say goodbye. Of course, son. Two weeks will fly by, Leon hugged his sons, trying to hide his anxiety.

Listen to Aunt Rebecca and Aunt Tiffany. When the door closed behind Leon, a tense silence hung in the house. Rebecca immediately began her duties, settling into a room next to the children’s room.

At their first dinner together, she observed especially closely. I’ll feed the boys myself, Tiffany declared. Tiffany, let me help.

You’ve been on your feet all day, Rebecca gently offered. No. Tiffany snapped, but immediately tried to soften her tone.

I mean, you see, we have our own ritual. The boys are used to me feeding them. Right, dear? The children silently nodded, but Rebecca noticed them exchange a look.

There was something troubling in the silent exchange between the twins. Late in the evening, when the house had quieted, Rebecca quietly entered the children’s room. The boys weren’t asleep, though they should have been asleep by now after taking their medicine, Aunt Rebecca.

Whispered Carl, Can we not eat that nasty soup tomorrow? What soup, darling? Rebecca asked. The one Aunt Tiffany makes. We always feel so bad after it.

At that moment, footsteps were heard in the hallway. Tiffany stood in the doorway. What are you doing here? It’s late.

The children need rest. I’m checking the condition before bed. It’s a mandatory procedure, Rebecca replied calmly, noticing how nervously Tiffany was fiddling with the belt of her robe.

I can check it myself. I always do. Go back to your room.

You’re the night sitter, so stay in your room. Rebecca nodded silently and left, but didn’t go to her own room. She stopped around the corner.

She heard Tiffany quietly talking to the children, followed by the sound of a drawer opening. Soon, Tiffany came out of the children’s room, holding some bundle to her chest, and hurriedly disappeared into her own room. What’s going on here? Rebecca thought, returning to the children.

The boys were already asleep, but their sleep was restless. Thomas was mumbling in his sleep, and Carl was quietly groaning. Rebecca sat down between the beds, took out her notebook, and started writing down her observations.

The night promised to be long. The morning began with a thorough checkup. Rebecca measured the boys’ temperature, blood pressure, and checked their reactions.

Something was definitely off in the overall picture. She sat at the desk in her room, spread out the medical charts, test results, and her notes in front of her. Let’s go through this step by step, she murmured to herself.

Weakness, drowsiness, coordination issues. But why do the symptoms worsen after meals? And these strange fluctuations in condition. She took out her phone and dialed Marcus’ number…
