Wife E has an extraordinary memory for numbers -- particularly telephone numbers and car / automobile registration numbers. With this in mind, a woman took to vandalising advertising hoarding in Cape Town's Atlantic suburbs. E saw a woman pull up at night in a luxury car to vandalise some hoarding, and kept the registration number in her head. This was the catalyst in solving the crime. The police found their man -- which is, their woman -- on the basis of E's excellent memory. I don't know how the story continued. With a crime like that, I would expect that the woman had a narrow escape. OBSERVATION: I find (I think) that those who did not use much writing in their younger years have an extraordinary memory for numbers -- and an extraordinary sense of time.
