Hall gave him the gist of the letter as he understood it. "But I still think he's a fraud, Pepe. Let's examine the labels on his clothes again."

The labels revealed only what Androtten had already indicated. London, Amsterdam, New Orleans, Rio. He had purchased no clothes in San Hermano.

"Let's get out of here, Pepe."

"Where are you going now?"

"I've got to write a letter in my room. But wait for me. I think we're going to visit Duarte when I've got the letter finished."

His own room, he soon discovered, had also been searched that day. The lock on his traveling bag had been picked, and the stethoscope was missing. He flung the new straw hat in the closet and went to the lobby. Pepe was talking to the day clerk. He grinned at Hall, asked, "So soon?"

"I changed my mind." Then, to the clerk, "Where is Miss Olmstead? At the University laboratory?"

"No, señor. She went to the country with the two doctors."

"Do you know where exactly?"

"No. Only that she went to the country. They will not be back tonight. They left an hour ago."
