In London, before the First World War, where in society love and money predominate, Bertha and Nigel had been inseparable. But then Nigel felt he had to focus on the economics of life, and after all Bertha's family were quite modestly off. Whereas the heiress Mary, also interested in him but not anywhere near so charming, was very well set up. His decision was made.

Though initially heartbroken, Bertha realises quickly that she has escaped from a delusion. Equanimity returns, and she finds in Percy Kellynch a devoted lover, though one a little more sober and less racy. They marry, as do Nigel and Mary, and over time the two become friends again, though now with wise awareness on Bertha's side. Nigel begins to see his error, as Mary's jealousy and her wish to supervise his life take their toll. He finds comfort in simply seeing Bertha initially, but inevitably begins to wish for more. Bertha is not interested, having moved on, but, if noticed, Nigel's attentions could be misconstrued...

In the meantime, Bertha is also looking out for the future of a young friend, Madeline Irwin, who is smitten with Rupert Denison, a young man with rather too much of a penchant for patronising and "educating" young women. Madeline is impulsive, a little inexperienced and quite needy. Her headlong qualities precipitate problems very readily.

As Bertha negotiates several crises arising from Nigel's reviving attachment, she also tries to assist Madeline in avoiding her own self-created disasters. Much depends on Bertha's talent for good management and wise counsel in the perils of both their lives. She is determined to win over adversity, but it will be a strong test of her skills....

Bird of Paradise, Leverson's fifth novel, as radiant with wit and wisdom as those which preceded it, was first published in 1914.
