By Helen Fear | Wed Nov 13 2024

Moonflower Murders sees the very welcome return of Lesley Manville's amateur sleuth Susan Ryeland, in the sequel to Magpie Murders on BBC One.

Let's be frank, Lesley is always immensely watchable in anything she does, whether it's Sherwood or a film like The Critic. But combine her performance with a murder mystery and we're totally sold.

The detective drama catches up with Susan after the events of Magpie Murders, and she is living a very different life in Crete.

However, her new life is disturbed by a baffling unsolved murder from the past. And she must uncover the secret hidden in plain sight...

Here's everything you need to know about Moonflower Murders on BBC One and iPlayer, including plot, cast, and start date.

Is Moonflower Murders a sequel to Magpie Murders?

Moonflower Murders is indeed a sequel to the series Magpie Murders, which first aired in 2022.

In Magpie Murders, we met publishing editor Susan Ryeland for the first time when she received Alan Conway's unfinished manuscript of an Atticus Pünd mystery - and got drawn into a web of intrigue and murder.

Now she's back in this 2024 sequel. The Magpie Murders book series is written by acclaimed author Anthony Horowitz. He's written more than 50 books, including the bestselling teen spy series Alex Rider.

What is the plot of Moonflower Murders?

In Moonflower Murders, Susan has left publishing behind and is now running a hotel in Crete with her long-time boyfriend, Andreas.

However, it's not as idyllic as it sounds and Susan eagerly takes up the chance to solve the puzzle of a missing woman whose parents have flown over from England. They insist that the answer to her disappearance is hidden away in one of Alan Conway's books.

Susan investigates a murder committed at a British country hotel eight years ago. At that time, author Alan Conway visited the hotel and wrote a novel based on what happened there. Cecily Treherne, the young woman who helps run the hotel, read the book and believed the wrong man had been arrested. Now she has disappeared...

Susan must return to London in an attempt to uncover the secret hidden in the book. Can she find Cecily before it's too late?

Is Magpie Murders and Moonflower Murders based on a book?

The TV series Magpie Murders is based on the 2016 mystery novel by British author Anthony Horowitz. It's the first novel in the Susan Ryeland series.

The story focuses on the murder of a mystery author and uses a story within a story format.

Moonflower Murders is based on the second novel in the Susan Ryeland series, which was published in 2020.

Is there a series 3 of Magpie Murders?

Although the Beeb has not yet confirmed a series 3 of Magpie Murders and its subsequent spin-offs, there is a third novel coming soon.

The third in the Susan Ryeland books, Marble Hall Murders, is due to be published in 2025. That means it's more than likely that a TV adaptation will follow shortly afterwards. Watch this space for more news.
