I do like this, the one flaw I find is that I feel that the mystery might all be revealed if the frame was not clipped at the bottom. The mystery is not ineffable or unknowable, it's simply been cropped out. That feels like a bit of a cheat.
Sorry to disappoint but the mystery has not been cropped out - wherever it is, it's not in the bottom left corner. Actually, it's a mystery to me too because I didn't have time to investigate as I was on the run myself.
