Description

Hey Sherlock!

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.
