All is dull and peaceful at Squire Grange. Lady Amelia searches for new ideas for her latest mystery novel as Sir Malcolm sleeps off the excesses of another idle day. Family friend Freddy is persuaded to try and think of new ideas. Meanwhile the hapless Vic Tim arrives and is promptly dispatched by an unknown assailant. Everyone tries hard to discover the murderer before he or she can strike again. The first problem, however, is how to get rid of Vic`s body, not just because he is making an untidy mess on the stage, but also because he has to come back in ACT II as a policeman! Smalls, the butler, and Mabel, the maid, try to assist the inept police (and Sir Malcolm attempts to give the delicious WPC Nunall a hand too) but not in time to prevent the Producer being murdered. There is even a suspicion that someone may have poisoned the audience. Eventually Miss Marbles arrives to reveal, Agatha Christie-style, the culprit, who also happens to be the play`s prompt. Or is there another culprit? This hilarious farce steadfastly refuses to take itself (or anything else) seriously.
