Question

Miss Morstan received a pearl every year. Give reason.

Answer 1

Based on Holmes’ deduction, the pearls were being sent to Miss Morstan as compensation for being deprived of her father. Since Miss Morstan started receiving the pearls shortly after Major Sholto’s death, Holmes had reason to believe that Sholto’s heir knew something about Miss Morstan’s father’s disappearance and was thus trying to compensate for the “wrong” that had been done to her all those years ago.
