Ratio Holmes and the Case of the Boston Ball Cap. This item is unavailable.Ratio Holmes and the Case of the Boston Ball Cap

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!

Ratio Holmes is not a detective. That is until Tommy Fist, the tallest, strongest, and most short-tempered boy in school decides that Ratio is. Tommy wants back his Boston Red Sox baseball cap. And Ratio is going to find it, or else. Along with his best friend, now colleague, Jinju, Ratio takes on the case. Not that he has much choice. Figuring out how to be a detective is hard. Trying to stay honest and also unharmed may be even harder. Combining footwork, creative thinking, and intuition, Ratio and Jinju solve the case, return the hat, and leave everyone involved unbruised and unbroken.

Horatio Holmes, author of the Ratio Holmes series, has grown a lot since his days at Longtides Elementary. Since then he learned to play the bugle (badly), worked as a writer of competitive mathematics problems, even acted in Hamlet playing the very character for who he was named. In other ways, he's still the same as he ever was: an avid reader, a pursuer of justice, and someone who likes his hot dogs with mustard.
