Three mysteries from the case files of Kid Detective, Bobby Easley.Something in the AirA fart was the case that blew Bobby Easley's way. A fart, an air bagel, a squirrely squeaker...Jack the Ripper. Four seventh-grade suspects. Four denials. That was typically the deal with farts. Not a lot of people turned themselves in. With his new partner, lil' sis, Ginger Easley, and her powerful sense of smell, they drill the suspects, recreate the crime scene, analyze the data, crunch the numbers, and cut to who exactly cut the queso.Cookie MonsterAnother cookie has gone missing without a trace. No crumbs. Never any crumbs...The Crumbler. Looks like the perfect job for kid detective and cookie enthusiast, Bobby Easley, but cracking the case of The Crumbler proves to be complicated. Forensic evidence is scarce. A ten year old only has so many resources. Bobby must rely on good ol' fashion gumshoe work in order to taste sweet victory.Aged GroundsLastly, over at a retirement resort some coffee beans have gone missing. Grandpa Frank's beans, to be exact. Kid Detective, Bobby Easley, must navigate the twists and turns and sift through the suspects; mostly a bunch of wrinkly, really old, old people, in order to solve the mystery of the missing coffee grounds and brew a cup of hot justice before the case goes cold.
