What is the point of view of the passage? What is the connection between the narrator and
Sherlock Holmes?

Since the passage was not included, let me explain the types of point of view and its advantages. You can answer better by understanding the techniques.

Explanation:

Point of view refers to who is telling or narrating a story. A story can be told in three different ways: first person, second person, and third person. Writers use point of view to express the personal emotions of either themselves or their characters. The point of view of a story is how the writer wants to convey the experience to the reader.

First Person Point of view: With first-person point of view, the character is telling the story. You will see the words "I," "me," or "we" in first-person point of view. This point of view is commonly used for narratives and autobiographies.

Second Person Point of view: When writing in second-person point of view, the writer has the narrator speaking to the reader. The words "you," "your," and "yours" are used in this point of view. Some common uses for second-person point of view are directions, business writing, technical writing, song lyrics, speeches, and advertising.

Third Person Point of view: Third-person point of view has an external narrator telling the story. The words "he," "she," "it," or "they" are used in this point of view. This point of view can either be omniscient where the reader knows what all the characters are doing in the story or it can be limited to having the reader only know what is happening to one specific character.
