Okay first off, Katataban, you need to edit your post to fix your image link.
Second, Red, I have a few questions:
1) I assume this is set somewhere nice and warm and sunny, like LA? I sort-of hinted at this by having Amber grow up in Hollywood. Can change if you like, or just assume she moved away from there after her last stretch.
2) If this is set any time after the 1950s, and the girls are going to be able to spend their wealth, one must assume that they at least wear some sort of masks over their faces while carrying out the robberies?
