Wicked Gang revolves around a narrator whose older sister was raped and murdered from years ago. A decade after his sister's murder, the young man now works for a small private eye company and his boss came up with the idea of helping victims of violent crime (or the victims' own families) to track down the whereabouts of the released-criminals.
Reluctant to take these cases, our narrator encounters family members of the victims: some of the victims were killed, some raped, some tricked out of their entire fortune, in one case a man was left by his irresponsible mother for death years ago and he wants to know where she is now; and the narrator also tracks down the criminals who had wronged those victims.
As the narrator works on his cases one by one, he comes to discover more clues about his sister's murderers (who had long been released from prison after serving no more than 10 years of jail time due to their young age). Burnt with a strong desire for revenge, what action will the young man take in the end?
The idea of the victims' families tracking down former criminals is an intriguing one. Once again Gaku Yakumaru brings up the questions of guilt, crime and punishment, redemption and forgiveness, good and evil through his writing, and I like how Mr. Yakumaru never gives you a simple black and white answer. In his stories, the difference between good and evil, guilty or not guilty is always shrouded with a lot of grey.
It is a thoughtful, fast paced and entertaining novel with a surprising ending at the very end. I strongly recommend you to read it.
