SK Datta, IPS, retired as Director of the CBI in 1993, has written his experiences for the benefit of readers, police personnel, politicians, professionals, journalists and also those in spiritual quest as beginners. In his 34-year career, his thinking mind focused on innovative ways. As SP of a district he saw inhuman treatment to dalits and became a champion for social justice, which he had already imbibed when as college student along with JN Dixit, former Foreign Secretary, he attended Gandhiji"s Wardha Ashram camp and did manual cleaning in Wardha town. He handled and specially deputed a fingerprint expert to lift latent fingerprints of Chopra children as the main evidence in the infamous Billa Ranga case. He wrote in the Statesman in the seventies for launching mass identification programme, which is currently being followed. The gestation period between an idea and its implementation is too long in India. He was assigned to deal with the dreaded gangs of dacoits including Phoolan Devi in Bundelkhand. Each act of bravery and martyrdom of police officers has been focused in the book to keep their memories alive including that of Dhrub Lal Yadav, who sacrificed his life in rescuing three British hostages kept in Saharanpur. In the Central Economic Intelligence Bureau, he devised his own method of detection of large-scale evasion of excise duties. He also observed that public servants were dealt with severely for acquisition of disproportionate assets, while for similar offence classified as "concealed income" under the Income Tax, affluent class received virtually no punishment, because methods of calculation are different. He has noticed how the investigation and prosecution of Syed Modi murder case, Anti-Sikh riots of 1984, Bhopal Gas Tragedy and other cases became difficult due to political interference. The Rajiv Gandhi murder, a blind case initially, carries his own and SIT"s contribution. His last challenging case was to supervise the investigation of the Security Scam cases. The description of all these cases in the book make it very interesting as well as informative.
