"You are certain those folks on the other boat are thieves?" demanded Sergeant Brown. "Carter and I don't want to go off on any wild goose chase."
"They are not only thieves, but abductors," said Dick. "We can easily prove it. They must be caught if it is possible to do so."
"All right then, we'll go with you. Come, Carter," and the two officers hopped on board. Soon the mainsail was set, followed by all the other available canvas, and the Searchlight was continuing the chase which had been so curiously broken off.
Martin Harris was in the dark so far as knowing what course the Flyaway had taken, and had to trust to luck to fall in with the fleeing craft.
"If she's going outside of Staten Island, I reckon I can spot her before long," he said.
"It looks to me as if the clouds were blowing away," said Tom.
"If they do, the starlight will help us a good deal."
As the yacht tore along through the water, the two police officers listened with close attention to what the boys had to tell them.
"If they are the men who robbed Rush & Wilder it will make a fine haul to capture them," said Sergeant Brown.
"We want to save Dora Stanhope as much as we want to catch those thieves," returned Dick. "I wonder if her disappearance has been reported to the police?"
"I can't say. You see, Carter and I have been out all day looking for a pair of harbor thieves who stole some clothing from a pleasure yacht lying off the Staten Island shore."
