Can you work out the 8-digit code and unlock the sarcophagus?
28416491
The hieroglyphics here have nothing to do with the password.
As you know from the safety notices on the spiral staircase (pages 88-89) to open the sarcophagus you must use the four missing numbers. The four missing numbers referred to are pages numbers. Throughout the book page numbers are missing from the footer on pages 28, 41, 64 and 91. Put those page numbers in chronological order to give you the code that opens the sarcophagus.
