A dangerous, escaped hitman! An art teacher who has lost her mind! A naked man covered in seaweed and talking in rhymes! But, what does it all have to do with the criminal mastermind, Mr. Who? It's up to Anna Smudge to find out! But Anna's no ordinary eleven-year-old. She's the top shrink in Manhattan, holding therapy sessions in a cramped storage closet in the lobby of her apartment building. Teaming up with a motley crew of friends, Anna embarks on an adventure that spans the landmarks of New York City. But how do you find a man when no one has ever seen his face? Does Mr. Who even exist? And if so, who is he?
