drug overdose case?

I came home from office. Leena is going towards the lift from her house. I came out of the lift. Leena is walking limping with the support of the wall. Her cheek is swollen and she has an injury on her head. I am shocked to see her in this condition. I could not say anything to her. Leena went to the ground floor by lift. Leena came back late at night like every day. I heard the sound of her house door closing. In the morning I got ready to go to office. I got a call from one of my colleagues. He said that we have to go to the police station with a client, you also come along. My friend is a criminal lawyer. He has been working on a drug overdose case for a few days.The case on which he has been working for the last few days is our good client. Our law firm handles all their corporate contracts and legal advice related work. My friend asked me to take a document from the office. I reached the police station with the document. My colleague is standing outside the police station. I gave him the document. He said I don't know how many more times I will have to work for this client. Sami, what if he is happy with you like last time, then you will get more money this time. You will become richer than me. Colleague, leave it, let's go inside. Sami, no, I have to go to the office. Colleague, come, I will show you the police station. He laughs. And putting his hand on Sami's shoulder, he takes him inside the police station. Sami, what is this case? The client's son takes drug overdose. Someone gave him a new type of drug. This happened after a party, which you had gone to that day. They have a suspicion on a girl.

Sami, but why? Is there any proof against the girl?

Colleague, no.

a girl comes there and goes towards the police officer's office. That girl is Leena.
