Kull with a single mighty leap hurled himself into the room. Tu spun, but the blinding, tigerish speed of the attack gave him no chance for defense or counter-attack. Sword steel flashed in the dim light and grated on bone as Tu toppled backward, Kull's sword standing out between his shoulders.
Kull leaned above him, teeth bared in the killer's snarl, heavy brows a-scowl above eyes that were like the gray ice of the cold sea. Then he released the hilt and recoiled, shaken, dizzy, the hand of death at his spine.
