Who can say how many husbands and wives have toyed with such thoughts as: “My wife? I could kill her ... and no one would know!’ And vice versa.
One author to have explored the subject is Peter James, whose novel The Perfect Murder spent 15 weeks at number one in the book charts.
His Roy Grace series of novels has sold more than 14 million copies and been translated into 36 languages.
Now The Perfect Murder has been adapted for the stage by Shaun McKenna and is playing at the Mill at Sonning from Thursday (January 21) to Saturday, March 12.
Victor and Joan have been married for 20 years. Too long. Victor would rather be with his mistress, Kamila; Joan wants to escape with her new love, Don. Only one answer to this marital crisis presents itself — the perfect murder!
And then young Detective Roy Grace is called in to investigate. It is his very first homicide case and as he delves deeper into the mystery, dark forces intervene.
It soon becomes clear that nothing — in love, marriage or murder — is quite as it seems...
The Perfect Murder stars Andrew Paul as Victor, whose TV roles have included parts in The Bill, EastEnders and Coronation Street.
Ticket prices vary but start from £43.50 (inclusive of car parking, a two-course meal, tea and coffee, the show and a programme).
