Every time I had to put it down, I cried a little inside. This book was entrancing from start to finish. While some readers may guess the killer's identity early on, this is still a quick-moving mystery distinguished by clear writing, memorable imagery, and some keen insights into human fragility. The chemistry between the protagonists is at the heart of the story, and their sparring relationship predictably, but enjoyably, develops into romance. Lock and Mori initially promise to keep no secrets from each other, but when Mori suspects her mother may have been involved with this and other murders, she withholds information, putting both teens in harm's way. The teens are both unmoored: Lock's mother is ill, and Mori's father has been abusing Mori and her brothers ever since their mother died six months ago. They are both curious, analytical observers, so when they learn of a bizarre murder, in which a man is found stabbed with his hands in his pockets, they decide to investigate. The narrator, James "Mori" Moriarty, meets the absent-minded, egotistical, and truth-obsessed "Lock" at school. Read at your own peril - nothing is more electrifying than the hunt for truth.Petty debuts with a suspenseful, sure-footed mystery, set in present-day London and starring a teenage Holmes and Moriarty. "True to canon, this sleuthing tale is rife with intrigues, puzzles, and vivid danger. Petty is a force to be reckoned with."-Ellen Hopkins, author of CRANK, TRICKS, AND TRAFFICK "A unique spin on a familiar tale makes Lock & Mori wise, witty and engaging.
