This is typical James Patterson and co-author. We have bodiless heads ,victims associated with hoodlums. What a start.Wealthy Chaz Smith murdered, linked to a criminal fraternity. The weapon has it's mysteries. His own family are not safe. Lindsay Boxer is perplexed as she arrives with partner Rich Conklin. Lindsay is pregnant but not shy of continuing her detective work and marriage to ex-FBI Joe. More deaths and heads follow. Emotional and professional conflicts do not interefere. Her longstanding colleagues are involved again. Claire the pathologist,Cindy the news reporter and Yuki the attorney. They add to the familiarity, continuity and the spice. Even these close friends are under scrutiny. The narrative is typically Patterson. Short paragraphs and chapters. The story keeps our attention and is not a lengthy read, but interesting. Easy to be critical of the formula but it still makes a grand read. The finale is as unpredictably as expected. Nothing particularly different as the formula works, but still quality and enyoyable. We may look forward to a different composition in the future but the ratings tell the publishers the success stories. This is another one.
