Edgar Rice Burroughs,
Tarzan and the Jewels of Opar
(1918)
“ The sentry's back was toward the corner of the hut which hid the giant black. The fellow did not see the huge form which silently loomed behind him. The knob-stick swung upward in a curve, and downward again. There was the sound of a dull thud, the crushing of heavy bone, and the sentry slumped into a silent, inanimate lump of clay. A moment later Mugambi was searching the interior of the hut. At first slowly, calling, "Lady!" in a low whisper, and finally with almost frantic haste, until the truth presently dawned upon him — the hut was empty! ”
