chunk: Weeks later, Holmes provides Watson with additional details about the case. Stapleton was in fact Rodger Baskerville's son, also named Rodger. His now-widow is a South American woman, the former Beryl Garcia. He supported himself through crime for many years, before learning that he could inherit a fortune by murdering his uncle and cousin. Stapleton had taken Sir Henry's old boot because the new, unworn boot lacked his scent. The hound had pursued Selden to his death because of the scent on Sir Henry's old clothes. Mrs. Stapleton had disavowed her husband's plot, so he had imprisoned her to prevent her from interfering.
  The story ends with Holmes and Watson leaving to see the opera Les Huguenots starring Jean de Reszke.
