Dorlock Holmes and Watkins set out to catch the Shropshire Slasher. Daffy (as Dorlock Holmes) does everything that he can, but it only takes a simple question from Porky (as Watkins) to bring the huge felon to justice. “I want to do what’s right… I do!” says the Slasher. “You always were a good boy, Slasher,” says his old flower-peddling mum. When Porky asks Daffy where he went to school, Daffy gives that classic ending line, “Elementary, my dear Watkins… Elementary!”
