Stroll on the Wild Side part 2 - S5-E8
Revealing mistake: Towards the end of the episode, when Murdoch attacks Falcone, look closely: the first punch - which knocks the mob boss down - looks convincing but the second time Murdoch "hits" him, he punches nothing but the ground. Falcone is facing right while the detective strikes his left side, at least an inch away from his head.
Suggested correction: The show is set in the early 1900's, which is the early 20th century. By the time this event transpired, SOS would have been established as a universal distress signal.
The show starts in 1895 and by season 2, it was still the 19th century and before Germany adopted SOS in 1905.
