The Road to Gundagai — Jackie French

Blue Lawrence has escaped the prison of her aunt's mansion to join The Magnifico Family Circus, a travelling troupe that brings glamour and laughter to country towns gripped by the Depression. Blue hides her crippled legs and scars behind the sparkle of a mermaid's costume; but she's not the only member of the circus hiding a dark secret. The unquenchable Madame Zlosky creates as well as foresees futures. The bearded lady is a young man with laughing eyes. A headless skeleton dangles in the House of Horrors.

And somewhere a murderer is waiting ... to strike again.

This third book in the Waltz for Matilda saga is set in 1932, at the height of the Depression. Miss Matilda is still running Drinkwater Station, but has put aside her own tragedy to help those suffering in tough economic times and Joey, from The Girl from Snowy River, uses his new medical skills to solve a mystery.
