# The Mystery of the Sarcophagus explained — The Insidious Dr. Fu-Manchu > Chapter companion for The Insidious Dr. Fu-Manchu by Sax Rohmer. ## What happens Nayland Smith, Dr. Petrie, and Inspector Weymouth investigate a double murder at Sir Lionel Barton's home. The Italian secretary Strozza and the Chinese servant Kwee are found dead under mysterious circumstances near an opened Egyptian sarcophagus. Smith deduces that Strozza was rifling the mummy case for jewels, while Kwee was hidden in the conservatory, likely as an agent of Fu-Manchu. The deaths are attributed to a strange green mist that emerged from the sarcophagus, which Sir Lionel later reveals was connected to the tomb of Mekara, a magician from the time of Moses. Professor Rembold had warned Sir Lionel not to open the sarcophagus, citing the similar death of Egyptologist M. Page le Roi. ## Themes in this chapter ### Yellow Peril The chapter frames the East as a sinister, intangible force, symbolized by the green mist and Fu-Manchu's hidden agent Kwee. ### Science and Occultism The mysterious green mist from the sarcophagus blends ancient Egyptian magic with a quasi-scientific agent of death. ### East vs. West Smith represents British efficiency and rationality, while Fu-Manchu's influence and the Eastern artifacts embody a threatening, insidious power. ## Character check-ins ### Nayland Smith Investigates the double murder, deduces the roles of Strozza and Kwee, and connects the deaths to Fu-Manchu's schemes. ### Dr. Petrie Assists Smith in examining the bodies and the sarcophagus, and questions the supernatural elements of the case. ### Inspector Weymouth Collaborates with Smith at the crime scene, provides details from witness Croxted, and expresses uncertainty about the green mist. ### Sir Lionel Barton Returns home to find the murders; reveals he was warned by Professor Rembold not to open the sarcophagus of Mekara. ### Kwee Found dead on the conservatory steps; Smith believes he was a concealed agent of Fu-Manchu. ### Strozza The Italian secretary, found dead beside the sarcophagus; he had locked himself in the study to steal jewels. ## Key lines > It was symbolic of the subtle, intangible power manifested in Dr. Fu-Manchu, as Nayland Smith—lean, agile, bronzed with the suns of Burma, was symbolic of the clean British efficiency which sought to combat the insidious enemy.
