But nowadays there are so many detective series on television people have got very blasé about murder. This has made it difficult for theatres to find good thrillers to keep the audience interested for two hours.

But this week Eastbourne has succeeded with Richard Harris' psychological thriller The Business of Murder.

Although this three-hander was a bit slow at the start, the tension built up and the unexpected twist at the end took everyone by surprise.

Todd Carty, best known as Mark Fowler in EastEnders, is well cast as DI Hallett who is summoned by the mysterious Mr Stone to help him sort out his son who is allegedly dealing drugs and in serious trouble.

Nick Waring, who played Robert Smith in London's Burning and Hugh Manning in Doctors, is superbly creepy as the mysterious character. The third member of the cast is Dee, a successful playwright who has been invited by Stone to discuss a play his wife has written.

Jacqueline Roberts fills this role and is as confused as the audience about her host's intentions.

The play is directed by Ian Masters and Ian Dickens and the timing is just right. Despite the twist which you visibly see the evening does leave you asking questions which may never be answered. You just have to draw your own conclusions.
