Возм. скрытая цитата из La Chatte Blanche by Comtesse d'Aulnoy, в русск. переводе Мадам д’Онуа "Принцесса-кошка", но там руки просто "невидимые". англ версия "After passing through sixty rooms the hands that conducted him stopped, and the Prince saw a most comfortable-looking arm-chair drawn up close to the chimney-corner; at the same moment the fire lighted itself, and the pretty, soft, clever hands took off the Prince's wet, muddy clothes, and presented him with fresh ones made of the richest stuffs"
