Edgar Rice Burroughs,
The Master Mind of Mars — Chapter VI: DANGER
(1928)
“ You cannot succeed. When I close my eyes I know that it will be for the last time if my resurrection depends upon the successful outcome of the maddest venture that ever man conceived; yet I am happy, because I know that it is inspired by the greatest friendship with which any mortal woman has ever been blessed."As she talked I had been adjusting the tubes and now I stood beside her with my finger upon the starting button of the motor."Good-bye, Vad Varo," she whispered."Not good-bye, Valla Dia, but only a sweet sleep for what to you will be the briefest instant. ”
