Although this book appears to be about a female serial killer, that is actually more of a sub plot to the lead detective, Johnny Mann's Triad connections. The book would stand on its own without the serial killer plotline (and we love serial killers. In a totally non-creepy way). In fact, the book would have been better without it because that was our main problem with it. It made the book feel like there were two separate books trying to be merged into one and it didn't fit.
The serial killer, Ruby, was as irritating as nettle rash to the eyeball. She had a room of dolls and would assign her victims as a father to individual dolls. We think the way she talked to the dolls was meant to come across as creepy, but it was childish and annoying. There was also no way to guess who the killer was. In a book that has characters of different nationalities - Chinese, African and Indian - her nationality wasn't given. It just said she 'wasn't Chinese'. And when the killer was revealed, it seemed unbelievable. Serial killers would be our chosen subject on Mastermind (again, in a non-creepy way) so we know that the people closest to them often don't know, and they can appear to be the nicest person in the world, but this felt more like it was done for shock value. Especially as Ruby was so childish and giggly, yet her real identity was completely different.
The rest of the book was interesting, as we don't know much about the Triad or Hong Kong, so it was nice to read a crime book that wasn't set in America or the UK. The scenes with the 49ers (teenagers recruited by the Triad) were chilling and fascinating. Johnny Mann made for an interesting character. He was trying to shake off his father's Triad connections and distance himself from that world, yet was being pressurised by his bosses to exploit those connections and delve deeper into the criminal world. And we loved the fact his weapon of choice were shurikans. That's much better than guns.
So take Ruby out of the book and it's worth a read. But unfortunately, she irritated us too much for us to score it higher.
