"There's a key in Muncaster Castle can break That maiden's heart in twain!" "Oh never, oh never, thou lying elf, That maiden's word is spoken: The cup of grace left a traitor's hand, Proud Muncaster's ' Luck ' is broken." Then scornfully grinned that elfin dwarf, And aloud he laughed again: "There's a key in thy castle, Sir Knight, can break That maiden's heart in twain!" The knight he turned him on his steed, And he looked over hill and stream; But he saw not that elfin dwarf again, He had vanished as a dream! The knight came back to his castle hall, And stabled his good grey steed; And he is to his chamber gone, With wild and angry speed.
