“This murder couldn't have happened here,” Cop A reasoned.
“But if not here, where? And by whom?” Cop B wondered.
“Got it!” Cop C proclaimed. “Waldo, in the library, with the globe.”
His companions looked at him. “Waldo? Have you gone mad?”
“Look! There's a red and white striped hat, and rented books, and a portion of Australia. Still think I'm crazy?”
Waldo was located and arrested shortly thereafter.
