There are several places that could be but I bet I know the one you mean.

I was looking at Scott Lynch's FAQ again the other day, and I noticed that the name of the series is "Gentleman Bastard", not "Gentleman Bastards". I really, *really* hope that doesn't mean that Jean has a target on his back. Locke is a fantastic character and I love him, but the books wouldn't be nearly as appealing if it were just him against the world. He needs a team, or at least a teammate. (Plus, Jean is five thousand kinds of awesome on his own.)
