"The fake detective!" exclaimed Bob. "Was that who it was?"
"The description fits him, doesn't it?"
"Yes," agreed Hugh, "but he was out at the old house this afternoon. How could he be on the river at the same time?"
"He was out at the old house early this afternoon," said Mr. Cook. "This episode at the bridge happened only about an hour ago."
"He must have hurried right down there," exclaimed Bob. "When he realized that the police were on his trail he probably decided he had no time to lose, and that's why he dared try such a thing in broad daylight."
"Where did you hear about it, Mr. Cook?" inquired Hugh.
"Sergeant Riley just told me over the telephone; I had called him up to inquire how Mr. Wernberg was getting along."
"How is he?" asked Bob.
"Pretty bad yet; once in a while he recovers consciousness, but only for a few minutes. Besides he suffers so from his burns he can't do any talking."
"And meanwhile his gang keeps on working," said Hugh.
