The production will precede a U.K. tour that is currently booking to the end of April, culminating in a run at Richmond Theatre in South West London April 25-30.

The cast is led by Dawn Steele, best known for playing Lexie MacDonald in the BBC drama "Monarch of the Glen" and Alice Collins in the ITV series "Wild at Heart." She is joined by Robert Duncan (Gus Hedges in TV's "Drop the Dead Donkey"), Ali Bastian (Becca Dean in "Hollyoaks" and PC Sally Armstrong in "The Bill" and a semi-finalist in "Strictly Come Dancing" in 2009), Peter Byrne ("Dixon of Dock Green"), Matthew Lewis (Neville Longbottom in the "Harry Potter" film series), Elizabeth Power ("EastEnders") and 60’s pop star Mark Wynter.

The play is produced by Bill Kenwright by special arrangement with Agatha Christie Ltd, and directed by Joe Harmston and designed by Simon Scullion.

According to press materials, the play revolves around a brilliant, idealistic Professor Karl Hendryk, who has been forced to flee persecution in his home country. But his world is turned upside-down when the prospect of life-saving treatment for his invalid wife persuades him to take on a new pupil against his better judgement; the spoilt, conniving Helen who will stop at nothing to get her way. With murderous intentions afoot, it only remains to be seen what verdict will be delivered, and if justice will prevail.
