Quotation from: The Chessmen of Mars

Written by: Edgar Rice Burroughs

"It is not a lie and I can prove it," retorted I-Gos. "Didst
notice the night that he returned from the chambers of O-Mai and
was boasting of his exploit, that when he would summon slaves to
bring wine he reached for his dagger to strike the gong with its
pommel as is always his custom? Didst note that, any of you? And
that he had no dagger? O-Tar, where is the dagger that you
carried into the chamber of O-Mai? You do not know; but I know.
While you lay in the swoon of terror I took it from your harness
and hid it among the sleeping silks upon the couch of O-Mai.
There it is even now, and if any doubt it let them go thither and
there they will find it and know the cowardice of their jeddak."
