OK, well I saw her "spelling out with her eyes" elephant (or elejhant or something), but the worRAB "van say" were being spoken in his mind when he saw the garage, and the guys washing the car seemed to be significant.
If it was just down to the elephant, then ok but still, I'm sure there could be other places with depictions of elephants in London (prime suspect of course would be the zoo, but maybe a creche or montessori?), so it seems a little tenuous, without anything else to back it up.
While we're on the subject, did he not think of calling in the location before going (or even while running) after the guy? At least if he failed to catch him, fell or anything his crew would have been around there quickly enough?
OK so far, but I'm finding it a little hard to follow the plot. See how it goes, I guess. How long is it. anyway?
