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 which now shuns them.
The War has, however, stolen Agnes's chance to graduate as a doctor, as well as the fiancé 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 was brought up by dingoes. The child cannot speak and seems deformed. But Agnes is inexplicably drawn to her and believes she can be cured.
The decision to save the child will bring Agnes's lost fiancé into her life again, as well as awaken the love of her husband who finds his voice as the three try to solve the mystery of the 'dingo girl'.
Agnes has put aside her own life and the dreams she once had. But now she has choices, with the main question the hardest: Who is Mrs. Agnes Mulberry?
