Midsomer Murders 2024: The Debt of Lies — release date, cast, plot and everything we know

The latest episode of Midsomer Murders 2024 is called "The Debt of Lies" and will be shown on ITV1 in July.

If you're a Midsomer fan you need to be Barnaby-like in your detecting skills to track down when each episode is being shown as ITV sprinkles episodes across the year! But luckily we've managed to track down when the next episode of the new series is being shown.

The plot sounds a little bit like Richard Osman's Thursday Murder Club in that it's set at a retirement community. To be exact a police retirement community where a resident is found dead. Being a load of ex-cops they're very keen to crack the case themselves and all eyes are on DCI John Barnaby (Neil Dudgeon).

Annette Badland, who plays pathologist Dr Fleur Perkins, told us she's very excited Tom Conti is among the guest cast. "I have to say, both Fleur and myself got a little hot under the collar! He's such an attractive, charismatic man and a wonderful actor. So I got a bit girlish and shy! But the one bad thing about playing a pathologist is that I don't get to perform with these guest stars unless they're dead, so they're usually lying on a bit of plastic on cold, wet grass or on the mortuary steel!"

Here's everything we know…

Midsomer Murders 2024: The Debt of Lies release date

Midsomer Murders 2024: The Debt of Lies is released on Tuesday, July 16 at 8.15 pm on ITV1. The episode will also be available to watch from that date on ITVX. This episode is already available on BritBox in the US.

What's the plot?

Barnaby and Sarah head to a party to celebrate the retirement of DCS Elaine Bennet. Barnaby doesn't know that Elaine is unwell.

The makers tease: "At the party, Sarah is introduced to Barnaby’s old gaffer — Sebastian Cabot – who informs the pair that Elaine is his new neighbor – she has recently moved into Challis Court. Set up by an independent charity fifteen years ago, Challis is a collection of desirable apartments within a grand estate providing comfortable and secure housing for retired police officers.

"A remark from Sebastian tells Barnaby that Elaine may not be as popular as the turn out suggests — her husband is not even in attendance. Barnaby is further intrigued when he notices Elaine having a heated argument with someone outside the party.

"As the event draws to a close, Barnaby sees that behind the handshakes and smiles, some of the officers are harboring resentment and bitterness. After bidding farewell to her colleagues, Elaine heads home… only to be later found dead in the Bennet’s family car after crashing into a tree.

"Barnaby and Winter arrive at the scene and realise there are no signs of braking, it appears as if Elaine deliberately drove off the road without a seatbelt and died of massive trauma. It is Fleur who corrects the pair and explains that the brake cable has been cut — this was no accident… And as Challis Court is a gated community that means the killer was inside and they are looking for an ex-officer.

"Barnaby and Winter must interview these retired officers who are wise to their line of questioning, and who are keen to offer their expert opinion on the handling of the case. Is an ex-colleague out for revenge? Can Barnaby steer through the lies to catch the killer before it is too late?"
