Numb3rs Fanfic Finders

I'm looking for a fic I read a while ago, but I can't recall exactly where. Charlie and Marshal Penfield are both consulting on a case, and they get in a car accident or something in the forest (they may have been run off the road...) and Penfield breaks his ankle I think. Anyway, I'd really like to read it again, but I can't seem to find it. If anyone knows what I'm talking about I'd be eternally grateful. :)
