Caro Swanson has taken a job in a remote part of Scotland.
She's answered an ad in The Lady: being a companion to an elderly gentleman who lives in a country estate could be perfect! Surely it's time to make a change and do something different for a while?
The fact that she may also see Alec, the young man who she met some years previously and who she has always thought of as her 'one who got away', is of course purely incidental.
Soon Caro is falling in love - not only with Alec but with the stunning country house she's now living in. But the estate is in financial difficulties, and Caro soon realises there's only one way to rescue it.
So begins a magical romantic summer, one that will take Caro from Scotland to London and the south of France, in search of a classic lost perfume that might just restore all their fortunes.
