There are already three people in Imogen Cameron's marriage - herself, her husband, Alex, and their son, Rufus - and that's just the way she likes it.
But then the Camerons are forced to accept an offer from Eleanor Latimer of a rent-free cottage on her estate. Ordinarily, such an offer is not to be sniffed at but as Eleanor happens to be Alex's beautiful, rich and frankly flirtatious ex, Imogen is very sniffy indeed. And with good reason.
Once installed in Shepherd's Cottage, Imogen's life is suddenly full to bursting with surly locals, psychotic chickens, mountains of manure, visits from the infuriatingly bossy vet, and of course Eleanor; who seems to be permanently at Alex's side. As far as Imogen's concerned, two's a marriage, three's a family and this! well, this is just silly, someone's going to have to go.
