“Do you have any suggestion?” asked Jack.
“My opinion is that we ought to keep away for a couple of days. That would make them think that they have scared us away. It will also make them a little careless and things will be easier for us to accomplish.”
“All right. Now suppose we do play dead, so to speak, for two days; then what?” asked Ken.
“Well, we still have to go down to the cellar for a second time and establish definitely what’s going on there.”
“And we still have to locate the exact position of their secret tunnel—for it must be that,” added Jack.
Paul nodded. “Yes,” he said. “It would be a simple thing to bore a tunnel connecting the two cellars.”
“But how are we going to determine how the fires and the robbery at Professor Link’s fit into the picture?” asked Ken.
“For that we will have to wait and see how things turn out,” explained Paul. “It may be very possible that those incidents have nothing to do with it all.”
“But those were the very things that we began to investigate,” insisted Ken.
“Yes, and now look what it got us into,” remarked Jack.
