"“Yes, sir, that be the house of Dr. Grimesby Roylott,” remarked the driver...."See in text(The Adventure of the Speckled Band)
Notice the way Doyle uses improper, vernacular grammar here to indicate the driver’s lower social standing. This gives the world of the story some verisimilitude and shows Holmes’s and Watson’s comparatively high level of refinement and education.
"Two days ago some repairs were started in the west wing of the building..."See in text(The Adventure of the Speckled Band)
Though Helen shares this development in the third person, it is clear that Dr. Roylott is responsible for the repairs and for potentially sinister reasons. One wonders whether Doyle uses the passive voice here to throw the readers off Roylott’s trail.
