Whiz and Joey witness an apparent breaking and entering. They instantly assume the roles of Agent M and Agent K of the Tanner-Dent Detective Agency. The victim doesn't want them investigating, which makes them more curious. They uncover spies, secret identities and the plans for a terrible crime. But nothing is as it appears as they ride for their lives up roads, through woods and cow pastures, until they find themselves on a wobbly swinging bridge. How do all their clues fit together? Can Whiz (uh, I mean, Agent M) find the connection?
• Could there be international spies in the quiet town of Jasper Springs?
• Can a simple breaking and entering-with no robbery-put Agent M and Agent K hot in pursuit of a bomber?
• What's really happening and what's not and how does the new Jasper Springs News intern fit in?
So many questions for Whiz and Joey to answer but time is running out for our young heroes as the Tanner-Dent Detective Agency must track down and analyze all the clues, which point to the biggest crime in the agency's history!
