It wouldn't be a country house weekend without a little murder. . .Three rival actresses team up to solve a murder at the stately home of Lettice Davenport, the author whose sleuthing creation of the 1930s, Dahlia Lively, had made each of them famous to a new generation. A contemporary mystery with a Golden Age feel, perfect for fans of Agatha Christie and Jessica Fellowes - and Janice Hallett and Richard Osman, of course!

In attendance at Aldermere: the VIP fans, staying at house; the fan club president turned convention organiser; the team behind the newest movie adaptation of Davenport's books; the Davenport family themselves; and the three actresses famous for portraying Dahlia Lively through the decades.

There is national treasure Rosalind King, from the original movies, who's feeling sensitive that she's past her prime, TV Dahlia for thirteen seasons, Caro Hooper, who believes she really IS Dahlia Lively, and ex-child star Posy Starling, fresh out of the fame wilderness (and rehab) to take on the Dahlia mantle for the new movie - but feeling outclassed by her predecessors.

Each actress has her own interpretation of the character and her own secrets to hide - but this English summer weekend they will have to put aside their differences as the crimes at Aldermere turn anything but cosy.When fictional death turns into real bodies, can the three Dahlias find the answers to the murders among the fans, the film crew and the family - or even in Lettice's books themselves?
