Although I have to admit I think of "Master of Disguise" as more of a Fall of the House of Luthor fic.
I was just about to point out that exact thought, John. It's a great story, but since it has more to do with Lois marrying Lex and the death of the DP, it belongs over at HoL.
You're right, of course. I just wanted to recommend it one more time.
Another story on this theme (Clark comes to Metropolis late, after Lois has already married Lex) is Sheila Harper's
In The Beginning . Another good read.
