When a sarcastic and unpopular ringmaster is murdered by an acrobat wearing a face mask and a Ninja-like costume, Stottlemeyer suspects an animal trainer who not only has a motive but also owns the murder weapon. Monk, however, suspects the ringmaster’s ex-wife, a trapeze artist billed as The Queen of the Sky who is also a sharpshooter. Meanwhile, the Monk alienates Sharona by telling her that her fear of elephants is irrational and advising her to suck it up.
