Private tutoring is booming and someones making a killing. An Autumnal Sunday morning, a hungover jogger stumbles across a dead body covered in blood, in Barnes Old Common Cemetery, a long-abandoned Gothic graveyard frequented by druggies and drunkards. The victim has spent the summer working in Italy for the wealthy Rivetti family, who appear have something to hide, as too do his bosses at the high-end Forum Tutorial Agency. And why are his old friends, who he'd been partying with the night before, quite so reticent when questioned? Enter DI Garibaldi, the Met's only non-driving, country music loving detective. His first step, to unravel the complex workings of the private tuition company, the Forum Agency.
