Keisuke Matsuoka (松岡 圭祐 Matsuoka Keisuke) exploded onto the literary stage in 1997 with the psycho-thriller Saimin (Hypnosis), which sold over a million copies in short order. Two years later he published Senrigan (Second Sight), with a former Air Self-Defense Force fighter pilot turned clinical psychologist as its heroine. The title has spawned a veritable flood of sequels, which have achieved combined sales of over six and a quarter million books to date (Matsuoka's agency has trademarked the Senrigan name). In 2010, Matsuoka launched the Banno kanteishi Q no jikenbo (Appraisal Case Files of the Omnicompetent Q) series, with nine volumes appearing in the span of a single year. He is known for deftly weaving global political issues and near-future projections into his works.
*sighs* It was a huge mistake to spoil myself with the ending when I was only in the middle part of Detective v.s. Detectives vol.3. Because of my spoiling the ending to my own self, I knew exactly who the arch villain truly is even before the big revealing part arrives, so most of the suspense and air of mystery is spoiled.
Even with the problem mentioned above (a problem which I had brought upon my own self) being put into consideration, I am still not satisfied with the main 'plot twist' of the story and how the heroine (a self proclaimed Anti-Detective) handles the crisis. In the first two novels the heroine had been badass and resourceful, but in this book she fell into obvious traps and I'm like: WHAT?
The writing is still terrific and I still like the dilemma between the heroine and her 18 years old assistant, even the final struggle between the heroine and the arch villain is intensive and exciting, still this revealing of the arch villain's true identity proves to be underwhelming and unconvincing, so 3.5 stars only.
