BRIAN CLEMENS is probably best known for his TV creations which include The Avengers and The Professionals, both hugely popular and not entirely based on real life.

Inside Job continues in the same vein. The plot has so many twists and turns that there’s an almost audible creaking as audience credibility is stretched to its limit.

During the interval we were trying to figure out why Clemens set the play in Marbella, on the Costa del Crime. One reviewer felt it would have played just as well in Milton Keynes. But in the second half all is revealed, and it has to do with over-zealous armed police, not normally found in Buckinghamshire.

Case closed.

Pretty young wife Suzy (Michelle Morris) chats up Larry, a jack-the-lad fugitive from British justice, and persuades him to help her leave her violent husband, Alex.

Matt Healy gives Larry a certain appeal, coming over as an engaging character down on his luck. Christopher Villiers, as Alex, seems jovial enough but has a violent temper aggravated by drink.

These three are actors of talent and experience, and give the appearance of being able to do this play in their sleep.

Their expertise keeps the audience interested through the laborious labyrinth of the plot, even managing to inject some humour.

As always, all is not as it first seems and a confusing amount is revealed in a couple of unwieldy speeches at the end. But I can’t fault the cast: Michelle, Matt, Christopher – you were great.
