“There are also a couple of more things that we have to check up on. For example, we still don’t know how Mr. Grey fits into the picture and—”
“Oh, I forgot to tell you,” interrupted Paul. “Following the grocery man, he and Mr. Grey passed each other and nodded. Whatever that meant I don’t know, but it establishes beyond a doubt that they know each other and that Mr. Grey is in with the crowd.”
“That’s very interesting to know,” said Jack enthusiastically. “But in that case, how are we going to explain his past behavior?”
“I don’t know,” answered Paul. “But there is no doubt that there is some connection between his past behavior and what we are up against now.”
“Yes,” muttered Jack, “I’d give a penny to know exactly how those fires and the robbery fit into the puzzle.”
“Eventually, we will solve that,” remarked Paul. “I have a notion how they fit in but—”
“Tell us!” exclaimed Ken.
“I would rather not; it sounds foolish and I may be mistaken. Besides, I couldn’t very well substantiate my argument. But what we have to decide now, is what we are going to do next, what our plan of action is going to be.”
