"Theres been a huge increase in the number of infidelity cases that we are called on to investigate. But the numbers are much higher in Mumbai and Delhi," says Puneet Kumar, vice-president, Global Detective Agency, Bangalore. Dileep Kumar, manager (operations) at Alert Detective Agency in the same city, agrees. Alert has recorded an unprecedented high in the number of teenagers spying on their beaus. He cites a typical case of a south Indian girl in her late teens hiring their services to spy on her north Indian executive boyfriend after a two-year affair. "The girl refused to believe our report on the guy and we had to run a check twice. The third time around, the girl came to us to verify if we were reporting on the right person. We had to show her the man at a traffic signal to prove that we were keeping an eye on her boyfriend."
