I do like your story, it's laid out differently than I am used to. I wished you would expand your story summary more than that short sentence. It might help with bringing more attention to the story.
And instead of adding a subtitle to the paragraph like "AFTER TWO WEEKS", it could be implemented into the paragraph like "The morning, two weeks later, Vijay..." I think you have a good basis, just some rearranging.
Like I'm reading a screenplay or script than a novel/story. For example 'Amar: "What are you saying?"' can be changed to "What are you saying?" Amar asked in a desperate voice.'
Your main paragraphs are great, it's just the dialogue is a little awkward but a super easy fix.
I meant it when I said it was a good mystery and thriller. There's a book you can get on kindle for like $2 I think will help you finase those details, since you have a good basis (How to Write Action Adventure Novels (Classic Wisdom on Writing Series) by Michael Newton). The onw that helped me the most is a series called "On Writing and Worldbuilding" by Timothy Hickson. Hope that helps! Keep up the great story!!!
