OFFICIALLY, THE SAHAR police precinct was among the safest places in Greater Mumbai. In two years, only two murders had been recorded in the whole precinct, which included the airport, hotels, office buildings, and dozens of construction-site camps and slums. Both murders had been promptly solved. “All murders we detect, 100 percent success,” was how Senior Inspector Patil, who ran the Sahar station, liked to put it. But perhaps there was a trick to this success rate: not detecting the murders of inconsequential people.
