What does it take to solve a crime? Inquiring kids want to know, so the super-sleuths at the Pinkerton Detective Agency have invited detectives-in-training to join them in unraveling a mystery. Along with the great story comes plenty of interesting projects, activities, and tasks. Imaginative watercolor illustrations feature visual clues just waiting to be found. Coded messages require deciphering. And to do their part, readers can start a case file, complete with paperwork, photos, a crime scene sketch, and other pertinent details.
