Shadows in the Moonlight by Robert E. Howard

A swift crashing of horses through the tall reeds; a heavy fall, a despairing cry. From the dying steed there staggered up its rider, a slender girl in sandals and girdled tunic. Her dark hair fell over her white shoulders, her eyes were those of a trapped animal. She did not look at the jungle of reeds that hemmed in the little clearing, nor at the blue waters that lapped the low shore behind her. Her wide-eyed gaze was fixed in agonized intensity on the horseman who pushed through the reedy screen and dismounted before her.

He was a tall man, slender, but hard as steel. From head to heel he was clad in light silvered mesh-mail that fitted his supple form like a glove. From under the dome-shaped, gold-chased helmet his brown eyes regarded her mockingly.
