The 39 Steps is a wonderfully British play and Paul Snook’s production at The Wharf is one not to be missed.

An adaptation of John Buchan’s novel, this is very clever and inventive play. Set in the 1930s, this gripping tale of murder is a laugh-a-minute and the script was perfectly executed by the cast of seven.

The play tells the story of stiff upper lip hero Richard Hannay, played by Chris Underwood, who was very comfortable in the role. He is forced to go on the run after the mysterious Annabella, played by Rocky Appleby-Dymond, is murdered in his London flat, and begins a journey to Scotland.

As he flees he met by the policemen, a farmer, a professor and B&B owners, all played by clowns Chris Smith, Kevin Smith, Martin Turner and Claire Warren.

They were fantastic, taking on numerous roles with ease. Changing accents, often within one breath, is no easy feat but timings were impeccable and the quick switches added to the humour. A special nod to Kevin Smith for his portrayals in wig and a dress.

The alluring Rocky also returns as shy but helpful farmer’s wife and a femme fatale.

It was truly impressive just how much was done with such a minimal set, little more than a window, a door and some chairs.

Comic timing is the key to a successful production of this play and the cast certainly nailed it.

At times it felt as though scenes were dragging on a little and could have been cut without impacting on the plot but the slapstick side mellowed out in the second act and the pace picked up.

A rollercoaster ride of murder, spies and slapstick, you can hardly ask for more form a production. This was a tantalising and thoroughly enjoyable performance.

The 39 Steps is at Wharf Theatre, Devizes, until Saturday.
