Who was Mcmurdo

During this “story within a story," we learn that Douglas once bore the name “Jack McMurdo," and that he was part of a notorious gang in the United States, which was not unlike the Mafia. At the end of Part II, however, we learn that “McMurdo” is really a Pinkerton detective named “Birdy Edwards." Throughout all three of his “identities," Douglas is described as fearless, intelligent, and good-humored. Douglas is an example of Conan Doyle’s skill as a writer, in that the reader is able to accept with little difficulty the composition of the “three-in-one” character.

Douglas also known as mc murdo and birdy edwards now th story itself has two parts continiously going on,one part of vermissa valley in 1875; one in which holnes investigates the dead body claimed to be one of douglas but in reality it was baldwin whom he killed in self defense and laid in his position, the problem of baldwin related to as in Scene 10 when mc murdo betrayed the lodge and got them all arrested now relating to the present date of 1895 ( even though we are in 2024 we will consider 1895 present date) Baldwin returns to kill mcmurdo but instead dies himself.
