My New Year's Eve Among the Mummies, Classics To Go

J. Arbuthnot Wilson (pseudonym of the real author, Grant Wilson) tells this short story of his strange night spent inside "the great unopened Pyramid of Abu Yilla" in Egypt. On New Year's Eve, on the night before his group was to take a guided tour and climb the still sealed pyramid, he set out on his own to walk around the pyramid to relieve his boredom. He happened to find the secret entrance stone, which he pushed open. What he experienced deep inside the pyramid was a once-in-a-thousand-years event. (Amazon)
