“No, none. I suppose it goes to his office.”

“Does he receive any visitors?”

“Very few. There are two men who occasionally come here to see him.”

“Do you know them?”

“No.”

“Where is his office?”

“Less than ten minutes’ walk from here,” said Vernon. “I will look up the number for you.”

“Never mind it, Vernon, at present,” said Patsy, detaining him. “On what floor is Doctor Guelpa’s suite?”

“The fourth.”

“Is it near the stairway, or elevator?”
