“We have to move fast then,” added Jack.

“But what are we going to do?” asked Ken. “What can we do?”

Paul leaned forward and whispered to his companions, “The police!” It struck them all at once that lately they had not thought of the police who might have saved them a lot of trouble and who were the most logical people to tell. Paul continued, “We have to tell the police right away before it is too late.”

“But wait a minute,” remarked Jack. “Do you think they will believe us. They are liable to think that we are inventing it all.”

“We have to convince them, that’s all there is to it.”

“We most surely do,” added Ken. “There is nothing we can do ourselves.”

“Oh, yes, there are lots of things we could do ourselves if we only thought of it,” commented Jack. “I don’t know how wise it is to tell the police. They may just take us for a bunch of crazy kids.”

“As I said,” repeated Paul, “we have to convince them.”

“I wonder how Mr. Grey fits into the situation. I would give a penny to know,” said Jack.
