Meet Ratio Holmes! He's not really the great, great grandson of the fictional character Sherlock Holmes, but all the other kids seem to think he is. Now he's a detective whether he likes it or not. Still, he's creative, good at thinking through facts, and has a wicked smart best friend, Jinju. Together, they might make great detectives after all!

B. Hanfell is the fourth grade bully and really likes Ratio's newly detailed bike. But when Ratio keeps B. B. from getting the bike, the bully finds another avenue to get back at Ratio. Can Ratio and Jinju find a way to recover stolen property without causing any more of what Jinju might call altercations and Ratio might call fights?
