My only clue was that she used exclusively panama rolling papers for her cigarettes. Things like that may seem insignificant to an untrained observer, but they make an experienced photographic investigator's life much easier… All I had to do was follow the imprint that the smell of the panama papers left everywhere they were used -sometimes for weeks- and wait. As it must be obvious to you by now, a successful photographic investigator must sharpen all of her senses with diligence, discipline and determination with every change she gets so that she is always ready to follow a sensory lead instantly. Of course the objective of my investigation about this particular subject was totally unrelated to the panama papers, but thank god she used them.
