The man Jule was watching so closely seemed to understand that he was under suspicion, and, seizing his companion by the arm, the two passed on together, turning their heads now and then to watch the progress of the boys down the street.
“Did you see that?” asked Jule as the boys stepped along.
“Did I see what?” asked Clay. “I heard a voice, that’s all!”
“That was Sherlock Holmes in disguise. Did you catch on?”
“Not than I am aware of!” laughed Clay. “What about it?”
Jule explained what he had observed in the man against whom the pressure of the crowd had brought him, and Clay agreed that the man he had heard speak in a remarkably pleasant tone had not been following them by accident.
“Those two men,” he said, “are the fellows the policeman referred to.”
“But why should men like those be following us?” asked Jule. “Why, he looked like a banker, or a lawyer, or a preacher. And what did he have that kind of a rig on for? It’s mighty funny.”
“You may search me,” Clay answered. “The incident only confirms the opinion expressed not long ago that we ought to get out of this city immediately. Alex and Case can take their outing in some other town.”
The boys walked swiftly down the street for a couple of blocks, turned into a side thoroughfare, called a taxi, and were driven swiftly back along a parallel street for two blocks.
