The final curtain closed on David Suchet's long-running television version of Poirot at the end of 2013, so it was always going to be hard for any actor to slip into the shoes of the well-loved Belgian detective.
Putting his 1930s hat in the ring for this theatre production is a well-known face and television regular, actor Robert Powell. Some may remember him from his comedy series The Detectives with Jasper Carrott.
The stage is superbly set in an extremely lavish art deco country manor house. Murder is quickly revealed as the head of the household, scientist Sir Claud Amory, is killed off with a cup of black coffee.
Murder mystery fans will enjoy the formulaic set-up, following every clue closely. There's the usual list of suspects played with enthusiasm by familiar faces including Liza Goddard (formerly of Bergerac), Gary Mavers (Peak Practice) and Ben Nealon (Soldier Soldier), but the highlight is actor Robin McCallum as Poirot's loveable sidekick Captain Hastings. He is a refreshingly funny stooge to Poirot's one-liners.

I don't want to give anything away, but there are plenty of motives, red herrings and twists that will keep you guessing right through to the end.
When it comes to the acting, Powell's performance is enjoyable enough, but he's just not managed to nail the finer details of Poirot, which we have come to expect from Suchet's portrayal.
This Poirot in comparison seems a bit too sprightly - he hasn't got the quirks that make him such a small and dandy figure of fun in the novels, and he even punches a suspect at one stage.

The accent is somewhat dubious at times and changes between Belgian and other European regions - even a little of Italian when he chats with a suspect from Italy.
Powell is not the worst culprit for this by far. There's an odd job of foreign accents from Gary Mavers and Olivia Mace, who are supposed to be Italian but occasionally lapse into something far different.
The accents don't impact on the overall effect and this is a pleasant affair to test the little grey cells. It also provides a welcome return of beloved Poirot to those who have been grieving since his television demise.
The show is around 2 hours and 15 minutess and includes two 10 minute intervals.
