Marty Frye is not your ordinary sleuth. Marty Frye is a poet detective--he makes up rhymes as he solves small crimes. When his friend Emma's diary is missing, Marty is on the case. When Katie's flour is nowhere to be found, Marty tracks it down. And when the brand-new Action Chuck figures mysteriously vanish from the toy store, Marty unravels the mystery.
