The once impoverished medical student Agnes Glock is now the fabulously wealthy Mrs Mulberry. Her estate in the mountains is magnificent, a haven for those too ravaged by the Great War to cope with the society that first condemned them to battle and now shuns them.

The War has, however, stolen Agnes's chance to graduate as a doctor, as well as the fiance she adored. Her husband, Douglas Mulberry, remains shell shocked and unable to speak. Their scandalous marriage is a farce, an act of kindness to keep Douglas's fortune from his uncle's grasp.

A chance visit to a circus brings about a mystery in the form of a fairylike child whose guardians claim she was brought up by dingoes. The child cannot speak and seems deformed.

The decision to save the child will bring Agnes's lost fiance into her life again, as well as the love of her husband, who finds his voice as the three try to solve the mystery of the 'dingo girl'.
