This is a horror story full of suspense . The main character is Ali .Ali thought returning to his childhood home would be nothing more than a painful trip down memory lane. Six years ago, his younger brother Sami disappeared without a trace. Not long afterward, Ali’s mother died, leaving behind one final warning that he never understood: “Don’t open the door when Sami comes back.” Now Ali has returned to sell the old family house—and the nightmares begin. Every night at exactly 2:17 AM, three knocks echo through the house. Then come the voices. His mother. His grandfather. And eventually, Sami. But there is no one outside the door. Behind the wallpaper, Ali discovers a mysterious door that shouldn't exist. Old photographs reveal something even more disturbing: the door has appeared in the house for generations, and everyone who tried to uncover its secret paid a terrible price. With the help of an old man who knows the house's dark history, Ali discovers that the room isn't simply haunted. It can imitate the people you love, steal their voices, and use their memories to convince you that they are waiting for you on the other side. But why does it want Ali? And what really happened to Sami? As the boundary between the past and present begins to disappear, Ali realizes that his family has been hiding a terrifying truth for decades. The room doesn't just appear in the house. It follows the person it wants. And when Ali finally escapes, he discovers that distance means nothing. Because the door has followed him. Now, at exactly 2:17 AM, someone is knocking again. Three times. And this time, the voice behind the door isn't his brother. It's his own.
