However there was one error that did take the gloss off slightly. Sherlock Holmes deduces that the flight must be a 747 as it has a seat K on it, as no other plane does. This is wrong; I know for a fact that the Boeing 777 has a 3-4-3 configuration and as it misses the seat I, that means a seat K next to the window on the right side of the plane. The Airbus A340-600 as flown by Lufthansa has a 2-4-2 configuration but that far right seat is also a K.
Picky? Maybe but how can I believe in the infallibility of Sherlock Holmes when he makes such an elementary mistake?
