The Sawdust Ring.

Janet sets out to find her circus ringleader father, who her mother abandoned believing him to be unfaithful. Along the way, Janet and her friend Peter join Colonel Simmonds's circus, she as a trick horse rider and he as a clown, but Janet cannot help but wonder why she finds Simmonds so familiar. The original, feature-length release of "The Sawdust Ring" is not known to survive.
