Dance reclaims its place in the second piece, inspired by the same novel and sometimes looking like material edited out of the first. Stateless, therefore, emphasises pattern and steps, with six Royal Ballet dancers forming couples who pick up threads of movement from each other or gel into brief unison. They seem like replications of the same couple, like Rachmaninov's accompanying 21 variations on a theme of Chopin. Or, like Jon Bausor's square pieces of foliage that have peeled off the floor and floated up into the distance, as if they were present events turning into memories.The choreography rushes and rolls, balancing on the edge of equilibrium; the spectacular lifts, with splayed limbs, are frozen moments of frenzy The emotional subtext is evident.

We may be inside Sophie's mind, the only territory known to this stateless person. But it is a man, Edward Watson, who closes the piece with a beautiful, textured solo.It is a fitting end to a consummate programme, which received only two performances and deserves a future series of repeats.. Children around the world will need to reinforce their school bags this summer. On 21 June, J K Rowling will finally publish Harry Potter and the Order of the Phoenix.

A late delivery, the tome will be Rowling's biggest brainchild – by a margin of more than 200 pages. But rumours that the author, 37, had suffered writers' block were scotched yesterday when her publisher Bloomsbury revealed the length of the teenage wizard's latest adventures. Order of the Phoenix will weigh in at 768 pages and 255,000 words. Harry Potter and the Goblet of Fire, deemed freakishly long, managed a mere 191,000.The children's literature specialist Nicholas Tucker said confident young readers would absorb the new blockbuster with glee "Children have enormous powers of concentration," he said. "We're often talking about ourselves when we talk about their limited attention span." But he feared the book's bulk would prevent it being read aloud to younger fans. "It will actually eliminate the adult narrator," he said.Goblet of Fire became the fastest-selling book in history on its debut in July 2000. Bloomsbury, which relies on Potter titles for half of its income, will be hoping to break more records.
