Stephen Black is found murdered on a tour bus visiting Crevecoeur Hall, where Hathaway's father was once estate manager so the sergeant knows the family. The murder weapon,a candlestick,is found in the family chapel and the priest once knew the victim,who was seen in the grounds a week earlier by Hopkiss the butler and Lord Mortmaigne's nephew Philip. Then the current estate manager dies,an apparent suicide,and Black seems to have known his wife Linda,who left him six years earlier. Whilst Lewis fears Hathaway's friendship with the family -especially daughter Scarlett,making a wealthy marriage to save family fortunes - makes him partial and gives him leave Black's colleague Frances Woodville tells Lewis that Black was after alleged buried treasure,dating from the Civil War, at Crevecoeur Hall. No treasure is unearthed but dark family secrets are,relating to the actual fate of Linda and the reason for Black's death.
