England in the Swinging Sixties: At the opening of the will of the wealthy Lady Harriet Hazelwood, a gruesome murder occurs! The suspects are not only the lady's vivacious niece and her arrogant brother, but also their wealthy uncle, who owns a stud farm. Or is there a ruthless murderer hiding behind the façade of the oh-so-puritanical aunt?

Scotland Yard, in the form of an amateurish Bobbie, is completely out of their depth in this case. Luckily, the clever Miss Molly is on hand to help with the investigation. The audience will help her to catch the murderer: Look forward to eccentric suspects and bizarre clues. You may be surprised at the special role played by a fat pug!
