A terrified scream echoed through the old, large mansion at midnight, but nobody inside actually responded to the awful noise. In the quiet morning, the housekeeper still found Sir Reginald dead in his study, a sharp knife in his chest. The large study door had always been locked from the inside, and the only window was also firmly, completely shut. Detective Miller slowly examined the scene with a very careful eye, also noting the overturned chair and several scattered papers. Yet the murder weapon was nowhere to be found, which made the whole situation seem utterly perplexing and deeply mysterious.
