I disagree on that one. If I thought that a murder is going to happen in a given location, and I knew that out of all the possible victims, one of them was constantly getting death threats, my mind would jump to that person immediately. Sure there are a bunch of other possible victims, but I'd at least acknowledge…

When I first watched the Sherlock pilot I was watching it back to back with that Luther episode also with a killer cabbie. It was funny how quickly the police on Luther figured out it was a cabbie in comparison

I didn't really like it because it felt way too sitcom, something I'd see on the big bang theory.
