Just after 8:00 p.m. on a Monday evening, Catherine Russell, senior vice president and director of business development at Western Banking Group, arrived at one of the branches she oversaw to catch up on some work. She saw movement inside the locked building and was taken aback?it was Rachel Dwyer, the branch manager; her son; and her boyfriend. "Why is she?why are they all in the branch after hours?" Russell wondered. This was yet another item on a list of curious situations Russell had encountered at that particular branch in the past several weeks. Maybe it was nothing, she thought, but that little voice inside was not so sure.
