Moonflower Murders plot: What's it about?

"There are lots of surprises in the second book, including something I've never done before in a murder mystery," said Horowitz. "It's going to be great fun."

In season 2, "Susan Ryeland's idyll in Crete", where she's living with her boyfriend Andreas, is "disturbed" when a murder committed eight years ago at a British country hotel rears its head.

"Alan Conway, Susan's prima donna former author, visited the hotel and wrote a novel based on what happened there – a novel that later led Cecily Treherne, who helps run the hotel, to believe that the wrong man is behind bars.

"Now Cecily has disappeared. Can Susan uncover the secret hidden in the book and find Cecily before it's too late?"

"What's coming up in Moonflower is quite unexpected, certainly for Susan," said Lesley Manville. "A couple, the Trehernes, a mother and father of two daughters, come to the hotel in Crete because they know Susan was the publisher of the Atticus Pünd books.

"Their daughter has gone missing and also they own a big plush hotel. They come to see Susan in Crete because not only has their daughter disappeared, but eight years prior on her wedding day, a murder took place in their hotel. A man was found dead.

"Before their daughter disappeared, she read Atticus Pünd Takes the Case, which is one of the novels that Alan Conway wrote, and she knows something about the murder that happened eight years ago that's made her disappear."

Manville went on to say that while "Susan is not a detective, nobody knew Alan Conway's books and the Atticus Pünd series of books like her".

"So they come to her and say, 'Would you come? We'll pay you £10,000 if you'll come to the UK and try and help us with your unique knowledge of the novel,' to help decipher what their daughter could read into the novel that made her realise that the wrong person had been put in prison for the murder eight years ago. And that something else that's made her disappear.

"And I mean Susan says, 'Look, we need the money.' And they do need the money, but really Susan's just kind of going, 'Ooh, yes. I can go back to London. I can dive into the Atticus Pünd books again.' So it's kind of too tempting a proposition for her to say no to."
