Holmes and Watson learn about a series of mysterious deaths of three men who were part of an archeology trip to Egypt. Each man was found strangled with a sheath of a mummy's wrapping present at each murder. The London Times believes the deaths were caused by an ancient mummy, creating public hysteria. Holmes and Watson decide take on the case to find the real culprit but they face a challenge since only one murder was in London while another was in Egypt and another was at sea.
