Read the following selection from the story.
"He investigated the case with great
care, for Dr. Roylott's conduct had
long been notorious in the county, but
he was unable to find any satisfactory
cause of death. My evidence showed
that the door had been fastened upon
the inner side, and the windows were
blocked by old-fashioned shutters
with broad iron bars, which were
secured every night. The walls were
carefully sounded, and were shown to
be quite solid all round, and the
flooring was also thoroughly
examined, with the same result. The
chimney is wide, but is barred up by
four large staples. It is certain,
therefore, that my sister was quite
alone when she met her end. Besides,
there were no marks of any violence
upon her."

selection?
