Mr. Newton was much excited over what Larry told him next day.

“Are you sure Detectives Jones and Douglass are on the case?” he asked.

Larry told what he had overheard at police headquarters.

“Then I guess they are,” remarked the reporter. “Well, this will be quite a surprise for them. It will kill two birds with one stone.”

“What do you mean?” asked Larry.

“We’ll get a story for the paper out of it and fool the officers besides.”

“It will be a queer story,” said Larry, and Mr. Newton nodded.

For several days after that, the men in the rooms below the Dexter apartment were busily engaged. Larry no longer kept watch of them. Instead he kept a careful lookout on persons who loitered about in the street near the house. One evening at dusk he saw two rather poorly dressed men who walked up and down several times, and then ventured into the hallway of the house.

“I guess they are the detectives in disguise,” thought Larry. “It is almost time to spring the trap.”

In accordance with an arrangement he had made he telephoned to Mr. Newton.
