The professor has always been an odd duck, but lately his behavior has been positively bizarre. He’s been talking to himself and stalking down the street with his collar turned up and his hat over his eyes, and now he won’t return Johnny’s calls. Johnny’s afraid that the professor’s old age is starting to get to him, but he will soon find it’s something far more amazing—and far more dangerous.
