It's a tiny thing in the Making Of The Private Eye digital download. One of a number of emails between Bryan K Vaughan and Marcos Martin. But this one had a curious title…
What the hell was that?
Oh yes… it must have been this article. I'd sent an e-mail to Bryan K Vaughan asking about the rumour that he was working with Marcos Martin on a second Image book to accompany Saga. Well, at the time I thought it was Image, though as the e-mails state, it was already planned as a digital first comic. I got no reply, though it seems Bryan and Marcos Martin discussed it a little, hence the e-mail above.
I also said "The title is also unknown. Well, I mean, they already know it, obviously. It's just that I don't have a clue."
Well, it seems they weren't that fixed on it either… it would be Masks at some point too.
