Perfect for you if...

  • You love crime capers that are genuinely funny, with banter and chaos that feels earned rather than forced.
  • You're invested in Stephanie's love triangle with Morelli and Ranger, and want to see where things actually go after 30 books.
  • You appreciate ensemble casts where the supporting characters (Grandma Mazur, her mum, Lula) are as entertaining as the lead.

Maybe not for you if...

  • You want gritty, procedural crime fiction where the stakes feel genuinely dangerous throughout.
  • You're starting the series here. You'll be lost without the relationship history and character context from earlier books.
  • You prefer your mysteries solved through detective work rather than stumbling into answers while things fall apart around you.

About this book

Stephanie Plum, a bounty hunter in Trenton, takes on an assignment to locate Andy Manley (also known as Nutsy), a former security guard accused of stealing diamonds from jeweler Martin Rabner's safe. She is simultaneously searching for Duncan Dugan, a fugitive arrested for robbing the same jewelry store on the same day. With her boyfriend Morelli away in Miami on police business, Stephanie cares for Bob, his large orange dog with a tendency to eat anything in sight. During Morelli's absence, security expert Ranger becomes increasingly present in her life. Meanwhile, Stephanie's best friend believes she is being stalked by a mythological demon intent on stealing her clothes. An overnight stakeout involving Stephanie, her mother, and her grandmother Mazur showcases three generations of determined women with exceptional driving abilities. As the body count increases and witnesses vanish, Stephanie must navigate a situation where everyone around her is acting dishonestly. She proves willing to bend her own rules to solve the case.
