Solomon Kane overpowers one Harpy and snaps another's neck

 But Kane dropped his rapier and with the bound of a blood-mad panther caught the demon's throat and locked his iron legs about its lower body.

Once again he found himself battling in mid-air, but this time close above the hut roofs. Terror had entered the cold brain of the harpy. He did not fight to hold and slay; he wished only to be rid of this silent, clinging thing that stabbed so savagely for his life. He floundered wildly, screaming abhorrently and thrashing with his wings, then as Kane's dirk bit deeper, dipped suddenly sidewise and fell headlong.

The thatch of a hut broke their fall, and Kane and the dying harpy crashed through to land on a writhing mass on the hut floor. In the lurid flickering of the burning hut outside that vaguely lighted the hut into which he had fallen, Kane saw a deed of brain-shaking horror being enacted—red-dripping fangs in a yawning gash of a mouth, and a crimson travesty of a human form that still writhed with agonized life. Then, in the maze of madness that held him, his steel fingers closed on the fiend's throat in a grip that no tearing of talons or hammering of wings could loosen, until he felt the horrid life flow out from under his fingers and the bony neck hung broken.
