Final answer:
The limited third-person point of view in the passage restricts the reader's knowledge to Utterson and Poole's perspectives, effectively building suspense.
Step-by-step explanation:
The passage in question utilizes a limited third-person point of view, which creates a specific effect on the reader. This perspective allows the reader to understand the events from only certain characters' perspectives, thereby contributing to the literary techniques of suspense and mystery. Specifically, the reader only has access to the thoughts and observations of Mr. Utterson and Poole, thus building suspense as the reader navigates the uncertainties and unknowns alongside the characters.
