The Murder Case and the Initial Investigation

In the summer of 1860, three-year-old Savile Kent is found dead with his throat slashed at the family's grand house in Wiltshire, England. The local police investigate but fail to find any leads, leading to national outrage. Detective Jack Witcher and his partner from Scotland Yard are called in to solve the case. Witcher suspects that the killer must be someone within the house, as the window used to gain access seems like a decoy. He becomes convinced that Constance Kent, the 16-year-old half-sister of Savile, is the culprit. However, he cannot gather enough evidence to support his theory, and his accusations are met with backlash and skepticism.
