Blue Rose with a Ted Nugent style pregen PC and an introductory adventure named "Magic Venison…"That or True20/Blue Rose seems like a good fit for a one player game.

I'd be tempted to run Trail of Cthulhu or Fear Itself for a one-on-one game. (Probably because my interest in GUMSHOE is high, at the moment, and I've had good results with one-on-one Cthulhu games in the past.)
