Murder mysteries are making something of a comeback at the moment, and the latest new addition to the genre is See How They Run, directed by This Country’s Tom George.

The film is set in 1953 against the backdrop of the 100th production of Agatha Christie’s The Mousetrap in London’s West End, and affectionately pokes fun at many of the tropes inherent in the whodunnit genre.

The film also boasts an incredibly starry cast, including Adrien Brody, Sam Rockwell and Saoirse Ronan, while a whole host of British stars such as David Oyelewo and Ruth Wilson serve as potential culprits when the murders begin.

Of course, any murder mystery worth its salt needs a satisfying denouement – and if you need some help recapping the events in the final scenes of See How They Run, you can read on to have the ending explained.

And of course, there are major spoilers for See How They Run below – so tread carefully.

 See How They Run ending explained

After Inspector Stoppard (Rockwell) and Constable Stalker (Ronan) go through a list of various suspects – with Stalker even suspecting Stoppard himself might be behind the killings for a while – the killer is finally revealed when several of the suspects each receive an invitation to the home of none other than Agatha Christie herself.

John Woolf (Reece Shearsmith), Dickie Attenborough (Harris Dickinson), Petula Spencer (Ruth Wilson) and Sheila Sim (Pearl Chandha) are among those to be invited, only when they arrive it turns out Christie actually hadn’t invited them at all, and someone else was in fact behind the invitations.

That person, it turns out, was Dennis the Usher (Charlie Cooper) who soon arrives on the scene and forces them all to gather in the drawing room, armed with a gun.

At this point, Dennis reveals that he was the real boy on whose case The Mousetrap was based and that he couldn’t bear seeing his traumatic story exploited for profit. He’d killed Leo Köpernick in an attempt to stop the production, and when that hadn’t worked out, he killed Mervyn Cocker-Norris as well, disgusted with the changes he’d made for the planned screen version.
