Chelo Gómez is a smart young girl in fourth grade who wants to emulate her hero, the immortal Sherlock Holmes who solved cases by grinding them up in his mind. Her cases are just as tricky as his: Are there really ghosts in the haunted mansion? Who stole Medardo’s journals? While the adults squeeze their brains, ideas ignite like bulbs in Chelo’s restless head. She’s not always right at the beginning, but the criminals always end up in her clutches. Each case is an adventure full of surprises that readers will enjoy well past the final word.
