"I know. Well," declared Barma Shah, "whether that man last night was a petty thief or a thug playing a lone hand to deceive us, we won't take more chances."

Barma Shah's method was simple. They drove on to Delhi and pulled into the old city after dark. There, Barma Shah let the boys off on a quiet street and continued on alone in the jeep toward Simla. He had given them an address where they could find him.

Only a block from where they were dropped off, the boys came to a rooming house that Barma Shah had mentioned. They stayed there overnight and began planning their next step, which was to reach the American Embassy without attracting special notice.

"See what you can find out, Chandra," suggested Biff. "Say that you're a student who would like to know about the United States. Remember, there are a lot of American nations, so be sure to specify the United States. Maybe we can slide you in there to pave the way for me."

All this was in keeping with advice from Diwan Chand in Calcutta, which Barma Shah in his turn had stressed even more; namely, that spies might be watching every move that Biff made. Events along the line had definitely underlined the need for caution. So Chandra, still wearing his European clothes, set out on a hired bicycle, the most popular type of transportation in India's capital city of New Delhi, which adjoined the old Mogul capital of Delhi.

A few hours later, Chandra rejoined the other boys in a colorful bazaar where he had left them.

"I have good news," he exclaimed. "Every week, students go by special bus to meet and talk with ambassadors from other countries."

"That sounds like a United Nations proposition," commented Biff.

"No, no," returned Chandra. "I checked that. They go to a different country's embassy every week. So I look at the list, and what do you think is next? United States! Tomorrow!"

"Nice work," approved Biff. "That sounds like our ticket, all right."
