Numb3rs Fanfic Finders

Hey everyone! This is a great group you've got here. I've been looking for a particular Numb3rs fic for weeks now, and I just happened to stumble across this site. I'm hoping maybe y'all can help me out?

I'm looking for a fic where Don and Charlie go to the bank, only to stumble upon a robbery.  I believe Charlie gets shot by one of the robbers, although it may have been Don?

Also, I'm not sure if it is the same fic, or if I'm actually looking for two seperate stories, but I'm looking for a bank robbery fic where at one point Don is in the bank and Charlie is waiting outside in the car. Don sends one of the robbers out with a false name, so Charlie will know something is up.

Sorry to be so vague in my descriptions, but it's been a while since I've read them.
Thanks!
