Anthony Pearson is not a spy. He’s not. We promise. He’s actually a school counselor, a child therapist, and the author of Baby Bear Eats the Night, illustrated by Bonnie Leick. But that didn’t stop him from digging for clues about “Mary Had a Little Lamb.” What he found made him imagine what could have inspired the rhyme: a sheep that is totally, absolutely, 100 percent in control of things . . . or maybe just 95 percent. And squirrels in sunglasses. Oh, and a witch flying a helicopter. But you didn’t hear about the Fairytale Bureau of Investigations from him. Anthony and his family live in deep cover in Georgia.
