Under all other circumstances imaginable? No, probably not. I’m barely suited for undercover work, otherwise.
Maintaining the guise of a used car salesman for a matter of a few days seemed to pose quite a bit of difficulty (maybe more than a bit if you were to ask Ray), and that was a lot less high-risk than the sort of thing that I would imagine any serious espionage would be required for.
I’m not a very good liar when the stakes are relatively low, never mind when they're through the roof, hence being expected to speak potentially giving way to effectively shattering the illusion and therefore ruining any ruse meant to be maintained altogether.
In short, it’s probably for the best if I’m never approached to do any such thing.
