Armed with a pair of purple rollerskates and a brain with as many connections as there are stars in the universe, eleven-year-old Sesame Seade is more than qualified to be Cambridge's number one self-made supersleuth. All she needs now is a mission. So when a student ballerina and aspiring journalist vanishes into thin air, some serious sleuthing begins. Very much against her parents' wishes, but with help from her friends Toby and Gemma and a conspiratorial duck, Sesame slips into the wings and solves the mystery of the missing dancer.
