Posthorn Gallop by Derek Benfield

In this sequel to 'Wild Goose Chase', Chester Dreadnought and his wife, Patricia, arrive at the ancestral home of Lord and Lady Elrood hoping for a quiet weekend, little suspecting that two villains, his old enemies Capone and Wedgewood , are hot on his trail.

War crazy Lord Elrood lurks in the flowerbed with his shotgun ready to repel attacks by the butcher's boy, the postman and other desperate characters.

Through the ancestral living-room wander Maggie and Bert, come for a two-an-sixpence worth of gawp and are suitably awestruck by the goings-on of the country house set.

Add a man-mad maid, vague Lady Elrood, an eccentric guide, and a scout master and you have a mad, hilarious and funny play.
