DCI Deepak Sharma

DCI Deepak Sharma is one of the detectives drawn into the investigation after a bomb plot rocks the Home Secretary's world. Methodical and quietly persistent, he digs through evidence and testimony with the patience of a man who trusts procedure over instinct, even as the case around him grows murkier and more political by the day.

Ash Tandon plays him as the show's ballast — a working detective in a drama full of operators and liars, someone whose diligence quietly needles at the audience's paranoia. He doesn't showboat; he just keeps asking the next logical question, which in this world of hidden agendas turns out to be its own kind of quiet heroism.
