The Girl in Room 105

This is the first book I read written by Chetan Bhagat. This is a crime thriller. Zara and Keshav broke up 4 years ago. One day he gets msg from the girl and goes to meet her and finds her dead body and tries to find who is the murder. The story was interesting a tutor in JEE Institue and his friend solves the case. Before he finds the true murder the watchman was jailed. In each chapter, we will think someone likes the suspect and finds he is not. In Climax we will know the story of why the murder killed her and who was the murder and it was predictable at the end of the chapter. I think this will also become a movie soon.
