He had discovered something
While reading the story, Tommy exclaimed and his mouth dropped open. He couldn’t believe what he was witnessing. He must be hallucinating! He examined the snapshot on his computer screen again and compared it to the book, and there was no doubt. It was a dead ringer!
He needed to confirm it
Tommy couldn’t keep his excitement in check. Is this really happening? He concluded he couldn’t be certain yet since he wanted to find a means to check that this book was exactly what he thought it was. And he knew exactly where to do it!
