"Redemption Games" (formerly "Killing Rain" and "One Last Kill") is the fourth novel in Eisler's John Rain series. Rain is a Japanese-American professional assassin, who has lived in both countries and feels at home in both. Formerly of the Japanese Secret Service, he is now operating as a private contractor, often with a partner Dox. Sometimes he works with the CIA or Mossad. Sometimes he is at cross-purposes with these agencies. Although there have been many secret agent and assassin type novels over the years, the Rain series is among the best well-written and the first few novels were filled with an insider's view of Tokyo and the environs that really took the reader inside Japanese culture. These novels also contain numerous passages giving the readers informative tips about how to assess a dangerous situation, what to look for when you walk into a hotel, an airport lounge, a restaurant, how best to quickly dispose of enemy combatants.
This novel takes Rain to Manila, Bangkok, and Hong Kong. He is working with a partner, Dox, an ex-US Army sniper with a good-old boy manner, loud and abrasive, living large every minute, but who somehow, when he goes into sniper mode, disappears into the woodwork. Rain got a referral for this job through his Mossad contact and sometime-lover, the blonde bombshell Delilah and part of the story, particularly after the job goes sour, is whether he can trust her and whether he can ever let down his guard around her. Often, their goals are similar, but she has allegiances that he ultimately does not have.
Rain is not your typical assassin (as if you know what a typical assassin is like). He has morals and ethics and qualms about killing in front of children, but he is deadly as they come, preferring to work close up and there are few professionals in an agency that are of his caliber. "Killing isn't the hard part," he explains. "Getting close to the target, though, that takes some talent." As does making it look natural, his speciality. The hardest part, however, is living with it after.
There are few secret agent type novels (and, although, Rain isn't a secret agent, the stories are part of that genre) that are this well- written and this accessible. Rain isn't casual about what he does as Bond might be. Rather, everything he does has consequences, largely because he is operating on his own and anything he does might offend an agency, seal his death warrant, or screw up a personal relationship for him. The meat of this book is not just bang-bang, shoot-em-up, but Rain's paradoxical difficulties with dealing with what he does and who he can trust. And, it is a book (or series of books) that really stands out in this genre.
