It can be a knock at midnight, a despairing phonecall, a letter, even a mere slip of paper bearing his name. "Please help my friend," writes a desperate S. Qamaruddin from Jeddah. "He has elephantiasis." The Saudi Arabian embassy requests him to arrange for a Jaipur foot. In cases such as the latter, he charges five per cent of the agency's expenses, but attends all calls from Mumbai for free. "Till date I haven't bought him a cup of chai," says a grateful G. Verghese (name changed), whom Gopalakrishnan had helped through his second heart attack. "My wife, who knew him at work, just rang him the minute I experienced the attack. He arranged immediately for a doctor, organised a hospital bed. I suffered a third attack. He was with us throughout. When my wife told him we couldn't afford the lakhs of rupees needed, he arranged for Dr Lekha Pathak to do both the angiography and the angioplasty for just Rs 20,000," says the misty-eyed chartered accountant.
