You’re on the trail of a werewolf that’s been terrorizing your town. After months of detective work, you’ve narrowed your suspects to one of five people. You’ve invited them to dinner with a simple plan: to slip a square of a rare antidote into each of their dinners. Unfortunately, you only have one square left. Can you divide it into perfect fifths and cure the werewolf? Dan Finkel shows how.
