It gives me immense pleasure to introduce the Book titled “Unsolved and Mysterious Criminal Cases of India” written by Kislay Tarun. In recent years, specifically in the late 2000s, crimes have taken up a major portion of Indian society. Forge about a decade, or a year, there are numerous criminal offenses that take place just in the span of one month. A few of them get registered as a case if an F.I.R is filed, few of them get solved, few of them always remain hidden and unknown as no one lodged a complaint and lastly a majority of the cases remain unsolved under mysterious circumstances while challenging the judicial mechanisms.
