The Mantis is the third book in Kotaro Isaka's Assassins series. I suppose you could call it a blend of crime fiction and black humor.
Review:
Kabuto is a highly skilled assassin who has wanted to retire ever since the birth of his son. Unfortunately for him, his handler, the Doctor, isn't about to let him go, nudging him towards high-risk jobs while hinting at the dire consequences should he decide not to follow through. Kabuto's wife and son, meanwhile, have no idea that he isn't just an ordinary worker at an office supply company.
Kabuto may be fearless while on the job, but around his wife it's another matter. His entire being is attuned to her mood. The one thing he wants to avoid is upsetting her, to the point that even his son has noticed how meek and submissive he is around her. At the same time, it's not that he dislikes being married to her. He does, however, find himself wishing to be properly understood, and so his few friends tend to be much like him, fathers with similar concerns and temperaments.
The book follows Kabuto as he lives his life and tries to figure out how to retire while also debating whether it would even be right/fair for someone like him to be free to live a peaceful life.
