You want to use four lights. Set them as spots and position them as follows: Aim two, one on each side, so that they hit the wall behind Vicky. Use white, but set the beam strength for maybe half. Aim the other two on Vickie, but position them so they have a longer throw. Again, one on each side, hitting her at a 45 degree angle from the top. Play with the beam strength, but this should do it.
