The winds of change are blowing through Scotland Street. Though Bertie is getting older, he can't resist an adventure to escape his domineering mother, and Bruce, ever the navel-gazer, will have to bring his best self to navigate the complexities of the pas de deux. While Alexander McCall Smith's delightfully warm and witty comedy takes some surprising turns, the improbable adventures of this quirky cast of Scots will affirm the heart and joy in Edinburgh's New Town.

Unusual requests are commonplace at the No. 1 Ladies' Detective Agency, but so are very ordinary ones, such as a plea for money: when a distant cousin calls on Mma Ramotswe to ask for help with another relative's hip operation, tricky questions arise in regard to family responsibility. Mma Makutsi and Mr J. L. B Matekoni are far from convinced of the merits of the request, but it is hard for Mma Ramotswe, with a heart her size, to turn people away.

Life for Bertie seems to be moving at a pace that is rather out of his control. In Drummond Place gardens, it seems that Olive has their future together all planned out. Meanwhile, upstairs at 44 Scotland Street, Bertie’s father, Stuart, is powerless to stop over-bearing Irene and her motion for Bertie to travel to Aberdeen on a three-month secondment. And, further up in the New Town, while Bruce Anderson plots with old-school chums, love blossoms in Big Lou’s Cafe. 

From a small town outside Edinburgh comes the news that a young boy has been recounting vivid recollections of a past life: a perfect description of an island off the coast of Scotland which he couldn't possibly know and a house there where he claims to have spent his former life. When the boy's mother asks Isabel to investigate his claims, she feels she must - of course! - help them learn the truth, and she and her husband, Jamie, set off for the island.

Retired publisher Susan Ryeland is living the good life. She is running a small hotel on a Greek island with her long-term boyfriend, Andreas. It should be everything she's always wanted - but is it? She's exhausted with the responsibilities of making everything work on an island where nothing ever does, and truth be told she's beginning to miss her old life in London.
