Plot Summary:Sherlock Holmes is approached by John Mason, a horse trainer who is worried about his employer's recent strange behavior. Sir Robert Norberton and his sister Lady Beatrice Falder live on their estate, Shoscombe Hall. Sir Robert is a keen horseman with stables known locally as Shoscombe Old Place. He has been under a great deal of pressure lately owing primarily to his financial situation. A moneylender, Samuel Brewer, has already visited the manor house once demanding payment but has now disappeared. Other bits of odd behavior have also been apparent. Sir Robert recently gave away his sister's beloved dog and Lady Falder is now only seen once a day when she goes for her carriage ride with her companion. Holmes and Watson are soon on site but it is apparent that Sir Robert is hiding something.
