n November 10, at 6:55 p.m., a phone rang at the Delhi Fire Services. The panicked caller told an officer that a blast had occurred in a car in front of the Red Fort. Within minutes, the roads near the high security area were chock-a-block with fire tenders, ambulances, and police vans, recalls the officer, who did not want to be named.

The scene, he remembers, was ghastly. There were shattered glass pieces, dismembered body parts, streaks of blood, and broken vehicle parts on Netaji Subhash Marg, the road leading to the Mughal-era sandstone structure.
