Mr clue and the lost princess

Previously

…But for now, Pippa was content to lose herself in the shimmering, ever-changing puzzle of the box. The kingdom slept soundly, bathed in the gentle glow of the restored Lullaby.

The world, she knew, was full of such delightful, perplexing puzzles, and she was always ready for the next one. The narrator, watching from the wings, smiled.

The universe, after all, had a rather inexhaustible supply of misplaced melodies and mysteriously carved boxes.
