The Mantis by Kotaro Isaka

The Mantis is a thriller about an assassin who just wants to retire, but knows his family would be under threat if he did. Kabuto works an office job, tries to keep on the good side of his wife, and worries about his son going to college. He also goes to the doctor’s office, but it isn’t any old doctor’s office: he is being given jobs for assassinations. Despite his skill in this world, Kabuto wants to retire, to pay his way out and stick to family life, but the doctor doesn’t want to see him go.

Having enjoyed Bullet Train and the combination of fast-paced thriller and dark assassin comedy, I was hoping for similar from The Mantis, and it didn’t disappoint. The narrative has a great balance of Kabuto in action as an assassin and Kabuto dealing with things like wanting to have a friend and trying to make his wife happy whilst his son sees him as a pushover. There’s some fun twists and turns (though nothing hugely surprising) and cameos/references to the events of Bullet Train, and generally this book is the same kind of good time you get from dark action films like the John Wick films (also with the assassin retirement theme). The pages flew by and as someone who usually prefers watching thrillers to reading them, Kotaro Isaka’s books really give me that experience.
