M. T. Krishna / Sanjay

Krishna appears at the Calcutta airport and whisks narrator Robert C. "Bobby" Luczak, his wife Amrita, and their baby Victoria to their hotel. Bobby, on a mission to collect a manuscript from the renowned poet M. Das, had expected an official greeter, but is grateful that anyone would meet them so late. In a high-pitched voice, Krishna claims to have contacts with the U.S. Education Foundation in India, and to have been sent by his boss, Mr. Shah, acting on behalf of Bobby's good friend, Abe Bronstein.
