There's one other thing that bothers me about this case - Dewani making contradictory statements was bad enough - but didn't the driver claim at first that he was approached by Dewani at the hotel?
And yet now the story runs that it was organised beforehand.
Also, the driver says he gets the feeling that Dewani has done something like this before. Then why, if this was the case, deal with a new person he doesn't know rather than go to someone - if you'll pardon the phrase - tried and tested?
I mean, think logically - if you've contracted someone to kill a person, and you needed a job done again, are you going to walk up to a complete stranger and blandly ask him to kill someone, or are you going back to the person who did it the last time? I know what I'd do ...
