Loved the episode but noticed one glaring mistake.
Holmes is British and only recenly arrived in New York, so the list of deaths on the blackboard was wrong, as far as dates is concerned.
The dates were shown in American format as month/day/year. As a Brit, Holmes would have written them as day/month/year.
A silly point, I know, but it just leapt off the screen at me.
