Sax Rohmer,
The Mysterious Mummy
(1903)
“ A man, gagged and bound, was imprisoned behind a great mummy case! Eager hands set to work to release him, and restoratives were applied, as he seemed to be in a very weak condition. He was but partially dressed, and breathed heavily through his nose, like a man in a drunken slumber. All waited breathlessly for his return to consciousness; for certainly he, if anyone, should be in a position to furnish some clue to the deep mystery. On regaining his senses, he had disappointingly little to tell. He was Constable Smith, who had been on night-duty in the Egyptian room. ”
