Silent Assassin
Moving without sound, unseen in his silky black coat, once he had slipped his trademark collar, nothing gave his presence away. That is unless you had a nose for him. Unleashed he left like a wraith, not even Reynard the fox could compete. His only nemesis was water, for faint ripples marked his passing.
Today he had left and returned, his duty done, before his guardian realised whom he had been sheltering.
