You can always enjoy a breath of fresh air in the Scottish Highlands, and the Theatre In The Hills allows you to experience some great drama at the same time.

This latest adaptation heaps even more fun and spoofery on to the original two actor concept by Simon Corble and Nobby Dimon.

Here there are four actors, playing a plethora of roles. Dougal Lee shows great comic timing as Richard Hannay and takes up almost a permanent residence on the stage, despite not playing any other characters. The other three tackle a host of parts - sometimes two or three at the same time - from German spies, variety artistes, policemen, Scottish yokels, landladies (and that’s just the male cast). The train journey in particular is a comic gem, with George Docherty and David Delve (appropriately listed as clown 1 and clown 2) in hilarious form. They are masters of so many quick changes of hats and accents.

Kathryn Ritchie joins in the fun with great gusto - from German beauty to dowdy wife with a few more in between.

Ken Harrison’s set is a triumph - the transformations from a London flat, to a train, the Forth Bridge, etc, are rapid and convincing.

Richard Baron has ensured this version cracks along at breakneck speed. This was a thoroughly enjoyable evening.
