Watson’s eye-level perspective after getting out of the cab and stopping where Sherlock tells him to stay while on the roof at St. Bart’s (using Google Earth, and street view). There is a short 1- story building between where Watson gets out of the cab and is looking up at the St. Bart’s roof where Sherlock is talking to him on the phone. The screen caps demonstrate how the actual street landing itself would have been further shielded from Watson’s perspective.
