No, it was a biography of Eric Lang.
OH!!!......the HORROR!!!!
Thankfully that was just a cover story Julia gave [spoiler]Jeff to supposedly explain away why they had Lang's papers. And, of course, that cover went out the window as soon as Jeff figured out the truth.[/spoiler] So, I suspect no one else really believed that or were even told it in the first place.
What is amusing, though, is that even after Julia admitted she was a doctor, she claimed to Liz that she really was writing a book. Funny how that book seems to have never shown up. Something tells me that even Liz figured out eventually that it was all just a bunch of BS.
