[1] A number of Streatfeild's children's novels have undergone similar retitling, linking them to her most successful book, Ballet Shoes.

[2] Wintle's Wonders draws on the author's own acting experience, and revisits the type of theatrical establishment seen in her adult novels The Whicharts and It Pays to be Good.

Rachel's father, George Lennox, was a budding film star, but died just as his career was taking off, when the children were seven.

Rachel is horrified by the type of dancing taught at Mrs Wintle's school, which includes tap, musical comedy, and acrobatics, and remains determined that Hilary will continue with her ballet.

Rachel discovers that when she is fifteen, she may be allowed to train for something else; this excites her, and she vows to send Hilary to the Royal Ballet School as soon as she can.

In the meantime she works hard in her own dancing, but she is still disliked by her aunt as she is not enthusiastic and even her best efforts do not make her, though competent, a good dancer.

Dulcie, meanwhile, gains a license to work as soon as she is twelve and immediately stars in a continuous line of pantomime, television and musicals.

Rachel soon follows, and is very much the opposite; she hates being onstage and is happy to be an understudy, and detests her uncomfortable Wonder uniform.

He is at a loss, as Dulcie is a pretty child and a talented actress, but cannot feel a role, as is required for the film.
