Uproar in the House

So Mr. Lockwood, the unfortunate builder of this modern monstrosity,
gets his Sales Manager, Nigel Pitt, to pretend to be the current owner in
order to make a more effective 'sell' to the first prospective buyers in
years. To give an additional touch of authenticity he engages an actress
to play the part of Nigel's wife, just while Sir Lindsay and Lady Cooper
have their look round. But the real complications start when the Coopers
are fogbound and have to stay the night-and turn out not to be husband
and wife at all. From here on the permutations become so intricate that it
seems impossible the authors can ever sort them out. But miraculously
they do, so hilariously that one can easily understand why audiences kept
rolling up to the Whitehall to see this play for such a long time.
