Hey Sherlock! — Simon Mason

Amy Roecastle is beautiful. Selfish. And missing.
Vanished without a trace in the middle of the night, she's taken her ferocious dog - and something else, too. Something deadly. Amy's best friend is lying to Inspector Singh, who has no leads and no idea.
Cue Garvie Smith. Teenage slacker. Undeniable crime-solving genius. Garvie's one step ahead of the investigation. But there's nothing simple where Amy is involved. And this time Garvie's about to find himself in way over his head.
