A white she-cat stood on a pebbly shore, serenely gazing over the dark blue water. The moon shown in the indigo sky, casting rays of light on the she-cat's snowy pelt. Stars glimmered in the sky, reflecting on the lake that was rippling with waves.
The she-cat closed her eyes briefly before standing. Her forepaws stretched forward as she arched her back in a long stretch. A voice behind her startled the she-cat into action. Her snowy fur ruffled in surprise, but lay flat a moment later when she spotted a black tom padding toward her. "Moonstripe…" he whispered.
The cats raced to each other, pressing their noses together, twisting their tails together. Each purred at the happy sight of one another. They lay down together in a nest far away from the lake shore. The Black tom fell asleep immediately.
The next night, the two met again. The ritual of pressing their noses together was performed, and then they sat together with the lake water rushing over their paws, then retreating. The black tom leaned his head against Moonstripe's shoulder and emitted a sigh. Abruptly Moonstripe turned on the black tom. She leapt onto his back and clawed at his spine. A furious screech found its way through the black tom's curled lips. Moonstripe turned him over and began to claw paw-fulls of belly fur from his soft underbelly. Then she stretched forth her paws, claws sliding out again. As her claws met with his throat, a small voice was heard from the black tom. "Moonstripe… what is… this?" he mewed deathly quiet.
Moonstripe rose to her paws, proudly watching yet another of her victims breathe its last breath. She slowly put her paws in the water, making sure to clean the blood from her fur. "Why Sparrowheart, I thought you'd never ask!"
Sparrowheart heaved a breath, a gurgling sound accompanying it. "Why…?"
Moonstripe turned back to him, the blood having disappeared. Sparrowheart let out a last sigh as the life left his body. The white she-cat let out a proud snicker. She leaned down close to his ear. "Because I wanted to, leader's son." Moonstripe pulled her white fur from between Sparrowheart's claws.
Moonstripe stalked up the side of the hill, already thinking of her next victim. Hm… I think Hailstorm will do. That RiverClan tom will never know what hit him, she thought as she entered into the ThunderClan camp. She grabbed a meager mouse from the fresh-kill pile, gulped it down, and trod to the warriors den just as the sun peaked over the rim of the stone hollow. She lay down in her nest, curling her tail over her nose and falling asleep with a last thought of, They'll never suspect the deputy would have done it.
