It was a quiet night in a small town called Greenfield.
The rain had just stopped, and the streets were almost empty. Most people were already asleep.
At exactly 11:47 p.m., something strange happened.
Knock. Knock. Knock.
Mr. Daniel woke up suddenly.
He sat on his bed and listened.
“Who is there?” he asked.
Nobody answered.
He walked to the front door and looked through the window.
There was nobody outside.
He opened the door slowly.
The street was empty.
Mr. Daniel looked left.
Nothing.
He looked right.
Nothing.
He closed the door and went back to bed.
But before he could lie down—
Knock. Knock. Knock.
This time, it was louder.
Mr. Daniel froze.
Then he heard another sound.
A voice whispered from outside.
“Open the door.”
He quickly stepped away from the door.
The strange thing was that the voice sounded exactly like his own voice.
He did not open the door.
Across the street, Mrs. Grace had also heard the knock.
She came out of her room and woke her son.
“Did you hear that?” she asked.
“Yes, Mum,” the boy replied.
They checked the front door.
Nobody was there.
Then, suddenly—
Knock. Knock. Knock.
They both jumped.
Mrs. Grace opened the door quickly.
Nothing.
But something was lying on the ground.
It was a small black envelope.
There was no name on it.
She picked it up and opened it.
Inside was a single piece of paper.
It had only four words:
“You heard it too.”
Mrs. Grace became afraid.
By midnight, almost everyone in Greenfield had heard the same three knocks.
The strange part was that nobody heard them from the same place.
Some people heard them from their front doors.
Others heard them from their windows.
One old man even said he heard the knock coming from inside his bedroom.
Everyone stayed awake.
Nobody knew what was happening.
Then the town's church clock suddenly stopped.
12:00.
At that exact moment, every light in the town went off.
The darkness lasted for only ten seconds.
When the lights came back, something had changed.
Every house had a black envelope lying in front of its door.
People were too frightened to touch them.
The next morning, the whole town gathered at the community hall.
Everyone brought their envelope.
When they opened them, they found the same message:
“Tonight, listen carefully.”
Nobody understood what it meant.
That night, people stayed awake.
They waited.
11:45 p.m.
11:46.
11:47.
Nothing happened.
Some people began to laugh nervously.
“Maybe it is over,” someone said.
Then—
Knock. Knock. Knock.
The entire town heard it.
But this time, nobody went to their door.
Instead, everyone looked at the clock.
11:47 p.m.
Then Mr. Daniel noticed something strange.
His clock was not moving.
Neither was Mrs. Grace's.
Neither was the church clock.
Every clock in Greenfield had stopped at 11:47.
Suddenly, Mr. Daniel's phone rang.
He looked at the screen.
The caller's name was:
MR. DANIEL.
His hands began to shake.
He answered.
For a few seconds, there was silence.
Then he heard three knocks through the phone.
Knock. Knock. Knock.
After that, a quiet voice said:
“Tomorrow, someone will open the door.”
The call ended.
Mr. Daniel looked outside.
The street was empty.
But this time, there was something standing at the end of the road.
A person.
Completely dressed in black.
The figure slowly raised one hand.
And waved.
Then the streetlight went off.
When it came back on—
the person was gone.
Nobody in Greenfield slept that night.
And the next morning, one house was found with its front door wide open.
The family inside was gone.
On the floor was a black envelope.
Inside it were five words:
“You should not have answered.”
