When an elderly German professor arrives at a Yorkshire Inn asking for a room and saying he knows the identity of the other guests, a premise which, after cancellations proves to be correct, you know you are in for an interesting evening.

There are several incidences of déjà vu – an unsettling concept which intrigued author J B Priestly – in this intriguing play which is set over the Whitsuntide weekend of 1937.

Mitch Capaldi is in all five – yes all five – of the plays by this talented group, and he injects plenty of mystery as the German Dr Gortler.

It is the fourth play for Al Wadlan as Sam, the landlord, and for Victoria Porter, his daughter Sally, and both get under the skin of their characters; he as the kindly philosophical father and she as the tougher daughter – with both trying to please their difficult guests.

Neil James, also in his fourth appearance, has proved his talent for complex characters who appear to be hugely confident and successful, but are on the verge of breakdown, more than a little stimulated by alcohol!

He plays influential businessman Walter Ormund, and it is clear from the outset that all is not well with his wife Janet, played with sympathy by Jessica Olim.

Richie Bratby had been set to play schoolmaster Oliver Farrant, but he was called away for a TV role and so Moses Lutfi took over the role embodying a troubled soul with underlying feelings of doubt.

An intriguing play – and I doubt if you will guess the end. It runs until Saturday with tickets available from the Tivoli box office.

There is just one more play in the season – Abigail’s party from Tuesday 23 – Thursday 25 August.
