Once upon a time the Prince of Felicitas had occasion to set forth on a journey. It was a late autumn evening with few pale stars and a moon no larger than the paring of a finger-nail. And as he rode through the purlieus of his city, the white mane of his amber-coloured steed was all that he could clearly see in the dusk of the high streets. His way led through a quarter but little known to him, and he was surprised to find that his horse, instead of ambling forward with his customary gentle vigour, stepped carefully from side to side, stopping now and then to curve his neck and prick his ears—as though at some thing of fear unseen in the darkness; while on either hand creatures could be heard rustling and scuttling, and little cold draughts as of wings fanned the rider's cheeks.
