The Mystery of the Graffiti Ghoul by Marty Chan

Marty’s life consists of events and people he’d rather avoid - the outlandish clothes his mother insists he wears; the school bullies; teen gangs; mean, slushie drinking Trina and now graffiti painting ghouls. In trying to discover who vandalized and sprayed graffiti on a school building Marty and his best friend Remi get themselves into humourous situations that lead to interesting discoveries. Marty, the self-described brain and Remi, the brawn of the duo, use their detective skills to solve the mystery of the Graffiti Ghoul while discovering friends in unexpected places.
