A vague discomfort stole through Bobby's surprise. He had never heard Paredes speak so seriously. In spite of the man's unruffled manner there was nothing of mockery about his words. What, then, was their intention?
Paredes said no more, but for several minutes he paced up and down the hall, glancing often with languid eyes toward the stairs. He had the appearance of one who expects and waits.
Katherine, Graham, and the doctor, Bobby could see, had been made as uneasy as himself by the change in the Panamanian. The doctor cleared his throat. His voice broke the silence tentatively:
"If this house makes you so unhappy, young man, why do you stay?"
Paredes paused in his walk. His thin lips twitched. He indicated Bobby.
"For the sake of my very good friend. What are a man's personal fears and desires if he can help his friends?"
Graham's distaste was evident. Paredes recognized it with a smile. Bobby watched him curiously, realizing more and more that Graham was right to this extent: they must somehow learn the real purpose of the Panamanian's continued presence here.
Paredes resumed his walk. He still had that air of expectancy. He seemed to listen. This feeling of imminence reached Bobby; increased his restlessness. He thought he heard an automobile horn outside. He sprang up, went to the door, opened it, and stood gazing through the damp and narrow court. Yet, he confessed, he listened for a repetition of that unearthly crying through the thicket rather than for the approach of those who would try to condemn him for two murders. Paredes was right. The place was unhealthy. Its dark walls seemed to draw closer. They had a desolate and unfriendly secretiveness. They might hide anything.
The whirring of a motor reached him. Headlights flung gigantic, distorted shadows of trees across the walls of the old wing. Bobby faced the others.
"They're coming," he said, and his voice was sufficiently apprehensive now.
