Lying in front of Harrison Opuku is a body, the body of one of his classmates, a boy known for his crazy basketball skills, who seems to have been murdered for his dinner. Armed with a pair of camouflage binoculars and detective techniques absorbed from television shows like CSI, Harri and his best friend, Dean, plot to bring the perpetrator to justice. They gather evidence--fingerprints lifted from windows with tape, a wallet stained with blood--and lay traps to flush out the murderer. But nothing can prepare them for what happens when a criminal feels you closing in on him. Recently emigrated from Ghana with his sister and mother to London's enormous housing projects, Harri is pure curiosity and ebullience--obsessed with gummy candy, a friend to the pigeon who visits his balcony, quite possibly the fastest runner in his school, and clearly also fast on the trail of a murderer.
