Got it!
From AKA Superman...
By Penny Barnes
By using modern criminology techniques. First, I've constructed a psychological profile of The Man Of Steel. I've taken that profile and factored in my theory of a secret identity. He's early to mid-twenties. Possibly thirties.
Probably a professional connected to mass communication. I've fed all this information into the computer, cross referenced with everything we know about Superman. At this point, it becomes simply about numbers. The computer takes over, digests the information and arrives at the most likely result.
