Dad

Dad(Story tree) Arun Sen’s son had not come home since the past two days. He has not been heard of.
Arun had gone to a club on New Year ’s Eve with his brother Arnab. He had to forget his grief in some way. Loud music was blaring. People were dancing in a trance. At one corner people were drinking to all glory. They were sitting at a table, drinking. Suddenly, Arun saw a man of around thirty. And Arun was not mistaken. The same thin figure, black hair, green eyes. The same facial structure as his mother. That was surely his son, Soham!
“Arnab, you go home. I will come later.”
Seeing him, Soham was trying to run away. He was escaping once again Arun chased him. Every now and then he could see the glimpses of Soham. And Soham was overtook in a minute.
"Why are you chasing me?" Soham asked as if he did not know him. But the shock of recognition had not left his eyes.
"Son! Soham! What are you doing here? Let's go home. Don't run away again."
"Well, dad! I can explain. You see, umm..."
“No ifs and buts! Come home quick.”

Reaching home, the first thing they did was to hug each other, cry, and forgive one another. Both of them had a good laugh on several things
Night time. Arun was busy with his laptop. Arnab was beside him, busy with his mobile. He saw Soham enter his room and close the door.
"Soham. What's the matter?" Arun asked.
“How did that man come here?” Soham asked pointing at Arnab.
“I don’t want my victims to die in surprise. I like to tell them why they were killed. You saw our attack on that girl, and the death of the man, didn’t you, old man?And mr Arun, I am not your long lost son! I am the one who killed that man. I want to finish off my witness.”
Without saying anything Soham took the porcelain vase from the shelf and broke it on Arnab's head. Arnab put a hand on his head and shouted,"Haha! You will be paying for this. Very soon.”
Soham was taken aback. In a moment the police entered the house and arrested him.
Till after dinner, Arnab had hidden himself. He had spoken to the police about this plan of his. During his killer’s speech, he had turned on the recorder and had sent it to the police before his death. The police was ready around his house.
Two days back...
Soham Sen was near his home when he saw few men teasing a girl. Soham stepped forward to stop the men. One man pushed him. Soham, enraged, rushed towards them. One thin man, with black hair, green eyes stabbed him. Arnab was passing by then. He was left out with a warning,"Old man, dare not speak about this incident."
On the day when Arun and Arnab had gone to the club the idea of acting as the man's father suddenly came to his mind. And he implemented it. He had to somehow avenge for his son’s death.
It was Arnab Sen’s son had not come home since the past two days. He has not been heard of. The reason is death.
It was a personal victory for Arun and Arnab.
