Who Robbed the Baboon?

Overview

A criminal has emptied the Baboon's cash register. The Baboon runs the zoo's bar. Whoever did it must be one of the monkey's employees. The Turtle, Gorilla or Lynx? Who could it be? Hermione begs Sherlock not to say "by all the dris and all the dzos" anymore. Sherlock thought this would be simple, but it's not as easy as he thought.
