The Case of the Pen Gone Missing / El Caso de la Pluma Perdida

When Toots Rodríguez approaches Mickey on the playground, he knows something is up. Toots, the prettiest girl in the fifth grade, never talks to Mickey, not even when they're assigned to work together on a class project. But Toots has come to Mickey because she's in trouble, and he's a detective. The real deal. He has a badge and a certificate after completing an online course two years ago.

"You have to believe me, Mickey. I didn't take that pen. I didn't." When Toots shines her big green eyes on him and insists repeatedly that she's innocent, Mickey's intuition tells him to run fast—in the opposite direction. But he's a sucker for a pretty girl, so he takes on the case of the missing pen.

Rumor has it that Toots stole Eddy's pen. It's not just any old pen; it's his dad's pen. It has the White House logo on it. Eddy's father, a senator from South Texas, got the pen from the President of the United States when he visited the White House last year. As Mickey begins his investigation, though, all the clues point to Toots and her newly ex-boyfriend as the primary suspects.
