The nanny began to notice strange marks every time she changed the baby’s diaper: at first she tried not to pay attention to them, but one day she decided to install a hidden camera — and what she saw made her freeze in horror 
Laura Martin had worked as a nanny for more than five years and believed she had seen almost everything. That’s why, when she started working in the Blake family’s home, nothing seemed suspicious to her. A spacious house in the suburbs, a well-kept yard, friendly parents, and a nine-month-old baby named Noah.
His mother, Claire, spent all day at work. The father, Michael, was a programmer and usually worked from home, shut away in his office downstairs. The first weeks passed quietly.
But then Laura began to notice something strange.
Every time she changed the diaper, she saw thin red marks on the baby’s thighs. Not a rash and not irritation. They looked too even, as if someone had squeezed the skin with their fingers. At first, she blamed the diapers — perhaps the wrong model or fastened too tightly.
After a few days, the marks disappeared. But then they appeared again.
And then came the sounds.
While Noah slept during the day, Laura increasingly heard footsteps upstairs. Floorboards creaking. Soft movements. When she asked Michael about it, he calmly replied that he had been sitting at the computer the whole time. Once, Laura went up to the nursery and clearly heard the door closing from the inside, even though the room had been empty just minutes earlier.
Her uneasiness turned into fear.
The next morning, when she saw a new mark on the child’s body, Laura realized she could no longer wait. She ordered a tiny camera and placed it in a corner of the nursery, aimed directly at the crib.
For the first two days, nothing happened. Laura even began to doubt herself and think she had imagined everything. But on the third day, after lunch, she decided to review the footage.
The first minutes were ordinary. Then suddenly the door slowly opened. Almost silently. Someone entered the room.
Laura knew immediately: it wasn’t Claire. And it wasn’t Michael.
It was a completely unfamiliar man. He walked up to the crib, leaned over the baby, and at that moment Laura’s breath caught at what she saw… 
Continuation in the first comment 
When the stranger leaned over the crib, Laura could barely breathe. The man acted confidently, as if this was not his first time. Carefully, almost routinely, he took the baby by the thighs, lightly squeezing the skin.
Noah did not wake up. He only sighed softly in his sleep.
The man stayed there for just a few seconds, then adjusted the blanket and left the nursery just as quietly, gently closing the door behind him.
Laura didn’t wait a second. She grabbed her jacket, the child, and ran out of the house without explaining anything to Michael, who at that moment was calmly sitting at his computer. Within an hour, the police were at the house.
The footage was reviewed several times. Michael turned pale when he recognized the stranger’s face. He knew immediately who it was.
It was his older brother — Ethan.
Officially, Ethan was considered missing. Several years earlier, he had disappeared after a fight with the family, and everyone was convinced that he had either gone abroad or died. But the truth was far more terrifying.
Ethan had been secretly entering the house through an old access point to the attic that only he knew about. For months, he had been watching the family, studying their routine, checking the locks, cameras, and alarm system.
He deliberately left those marks on the child’s body — not too noticeable, but disturbing. He didn’t want to cause serious harm, but to demonstrate something else. He was gathering evidence.
He planned to use all of this to blackmail Michael. Ethan wanted money. He wanted to show that he could easily enter the house whenever he wanted and do anything he wished to the child.
Later, the police found a backpack in the attic containing copies of the recordings, children’s clothes, and detailed notes about every single day of the family. Ethan was planning to contact his brother very soon.
If it hadn’t been for Laura.
