Quotation from: The Chessmen of Mars

Written by: Edgar Rice Burroughs

"I saw the dead O-Mai lying upon the floor of his sleeping
chamber with one foot tangled in the sleeping silks and furs upon
his couch. I heard horrid moans and frightful screams."

"And you are not afraid to go there again?" demanded several.

"The dead cannot harm me," said I-Gos. "He has lain thus for five
thousand years. Nor can a sound harm me. I heard it once and
live--I can hear it again. It came from almost at my side where I
hid behind the hangings and watched the slave Turan before I
snatched the woman away from him."
