Good deal

When you are not hiring or doing one thing keep this pistol (one pistol forward) with you at all times.

-You are a pistol a...ma..

- No problem. I have the power to give it to you. But give it to me when the job is done.

- Well, can I come today?

- Yes, of course. But be careful.

- Well, okay

Saying this, Rafi Sahib returned to the bungalow. He came home and saw the pistol moving. A loaded pistol. Seeing three bullets in the pistol, his anger erupted. If he had found the murderer of his sister, he would have killed him with these bullets in the same manner as he killed his sister. 
It happened. After seeing the pistol, he put it under the pillow and slept. He woke up when he was feeling sleepy. Every night, that girlish cry and Nupur's humming sound. He took the pistol from under the pillow and ran towards the sound. He shouted who you are. What do you want? 
As he came down, he heard the sound of gunshots and fired three shots towards the sound and was hit by someone. Suddenly he heard the sound of a revolver from behind and looked back. He saw OC Mahfuzur Rahman and some constables firing towards the sound. A little later. 
He told Rafi Sahib

- Are you okay?

- Yes, I'm fine, but you here?

We came to find your sister's killer and hopefully found it
