"M. le Roi," continued Barton, "discovered, but kept secret, the tomb of Amenti--another of this particular brotherhood. It appears that he opened the mummy case on the spot--these priests were of royal line, and are buried in the valley of Biban-le-Moluk. His Fellah and Arab servants deserted him for some reason--on seeing the mummy case--and he was found dead, apparently strangled, beside it. The matter was hushed up by the Egyptian Government. Rembold could not explain why. But he begged of me not to open the sarcophagus of Mekara." A silence fell. The strange facts regarding the sudden death of Page le Roi, which I now heard for the first time, had impressed me unpleasantly, coming from a man of Sir Lionel Barton's experience and reputation. "How long had it lain in the docks?" jerked Smith. "For two days, I believe. I am not a superstitious man, Mr. Smith, but neither is Professor Rembold, and now that I know the facts respecting Page le Roi, I can find it in my heart to thank God that I did not see . . . whatever came out of that sarcophagus." Nayland Smith stared him hard in the face. "I am glad you did not, Sir Lionel," he said; "for whatever the priest Mekara has to do with the matter, by means of his sarcophagus, Dr. Fu-Manchu has made his first attempt upon your life. He has failed, but I hope you will accompany me from here to a hotel. He will not fail twice." CHAPTER XII IT was the night following that of the double tragedy at Rowan House. Nayland Smith, with Inspector Weymouth, was engaged in some mysterious inquiry at the docks, and I had remained at home to resume my strange chronicle. And--why should I not confess it?--my memories had frightened me. I was arranging my notes respecting the case of Sir Lionel Barton. They were hopelessly incomplete. For instance, I had jotted down the following queries:--(1) Did any true parallel exist between the death of M. Page le Roi and the death of Kwee, the Chinaman, and of Strozza? (2) What had become of the mummy of Mekara? (3) How had the murderer escaped from a locked room? (4) What was the purpose of the rubber stopper? (5) Why was Kwee hiding in the conservatory? (6) Was the green mist a mere subjective hallucination--a figment of Croxted's imagination--or had he actually seen it? Until these questions were satisfactorily answered, further progress was impossible. Nayland Smith frankly admitted that he was out of his depth. "It looks, on the face of it, more like a case for the Psychical Research people than for a plain Civil Servant, lately of Mandalay," he had said only that morning.
